Numbers

Compound ideograph: 八 (split / eight, the original "dividing" character from earlier) + 刀 (knife) = to divide. The picture is direct: a knife cleaving something in two. The minute of time (1 minute = one 60th of an hour) gets its name from the same character because a minute is "a divided portion" of an hour. Identical across 繁體 / 新字体 / 简体.

Mandarin has TWO tones for 分 — another 破音字: — fēn (level 1st tone): verb "to divide" + the noun "minute / part / penny". 分 (divide), 分钟 (fēnzhōng, minute), 分手 (fēnshǒu, to break up — "divide hands"), 分类 (fēnlèi, classify), 三分 (sān fēn, three minutes / three points / three cents). — fèn (falling 4th tone): noun "share / portion / quality". 身份 (shēnfèn, identity / status), 部分 (bùfèn, part), 充分 (chōngfèn, sufficient).

Japanese has THREE on-readings — possibly the messiest pronunciation table in the entire script: — ブン (bun): 分析 (bunseki, analysis), 部分 (bubun, part), 自分 (jibun, oneself). — フン (fun) / プン (pun): time-counting suffix. 三分 (sanpun — note the rendaku), 五分 (gofun, five minutes), 何分 (nanpun, how many minutes). The voicing/devoicing depends on the preceding number — pure memorization. — ブ (bu): fractions and percentages. 三分の一 (sanbun no ichi, one-third). Kun-reading わ.ける (wa.keru, to divide) and わ.かる (wa.karu, to understand) come from the same root — "what is divided becomes clear".

何分 (nanpun) — "how many minutes?" — is one of the first questions a Japanese learner masters at the train station.

Memory aid: knife splitting a thing in eight — the original picture of "divide".

Traditional 萬 originally pictured a scorpion — early Chinese scribes associated the abundant egg-laying of certain insects with "countless / myriad". The character was then specialized to mean exactly 10,000. Both Japan and Mainland China independently simplified to the same form 万 — a rare convergent simplification. So: 繁體 萬 / 新字体 万 / 简体 万.

Critical numeric system difference: East Asian languages count by powers of 10,000, NOT thousands. Where English uses million (1,000,000) and billion (1,000,000,000), CJK languages use 万 (10,000) and 億 / 亿 (100,000,000). So one million in English = 100万 (hyaku-man, "100 ten-thousands") in Japanese/Chinese. This counting-convention difference is one of the most disorienting things for English speakers learning CJK numbers — and vice versa.

Mandarin: wàn, falling 4th tone (simplified 万). 一万 (yīwàn, 10,000), 万岁 (wànsuì, "ten thousand years!" — the traditional cheer for emperors, modernized to political slogans), 百万 (bǎiwàn, million — "hundred ten-thousands"), 千万 (qiānwàn, ten million OR adverb "by all means"), 万一 (wànyī, "in case / if by chance" — literally "one in ten thousand"), 万事 (wànshì, all matters).

Japanese: TWO on-readings. マン (man) is dominant — 一万 (ichiman, 10,000), 一万円 (ichiman'en, 10,000 yen — the largest common Japanese banknote, with Fukuzawa Yukichi on it), 万年筆 (mannenhitsu, fountain pen — "ten-thousand-year pen"). バン (ban) appears in 万歳 (banzai, "Long live!" / cheer of joy — the Japanese WWII-era cheer that English borrowed). Kun-reading よろず (yorozu) means "all kinds / myriad" in poetic and traditional contexts — 八百万の神 (yaoyorozu no kami, "the eight million gods" of Shinto) describes the countless deities of Japanese folk religion.

Memory aid: a scorpion abstracted into the largest cardinal number — many beyond counting.

代 is a phono-semantic character: 人 (亻, person) for meaning and 弋 (a stake / arrow) for sound. One person "substituting for, replacing" another is its core sense. From people taking turns and succeeding one another grew "generation, era, an age."

Korean hanja-sound "dae": 代身 (daesin, instead), 時代 (sidae, era), 世代 (sedae, generation), 代表 (daepyo, representative), 交代 (gyodae, shift / taking turns), 代理 (daeri, proxy), 現代 (hyeondae, modern times). It is a counter for the "reigns (代)" of a dynasty, and also marks age brackets (20代, 30代).

Mandarin: dài, 4th tone. 代表 (dàibiǎo, representative), 时代 (shídài, era), 现代 (xiàndài, modern), 代替 (dàitì, to replace), 古代 (gǔdài, antiquity), 交代 (jiāodài, to hand over / explain). Used in historical periodization, as in 朝代 (cháodài, dynasty).

Japanese: on-readings ダイ (dai) and タイ (tai), kun か.わる (kawaru), よ (yo), しろ (shiro). 時代 (jidai, era), 代表 (daihyō, representative), 交代 (kōtai, taking turns — a タイ reading), 身代わり (migawari, a substitute), 千代 (chiyo, a thousand ages). Japanese 千代 (chiyo) means "a thousand generations = eternity," appearing in 君が代 (the national anthem).

Memory aid: a person (亻) standing in for another — generations taking turns and succeeding.

全 is read as 入 (to enter) over 玉 (the 王-shape, jade) — possessing a flawless jade (玉) under a roof (入), hence "whole, complete, all." It points to a state fully provided, like an unblemished jade with nothing missing.

Korean hanja-sound "jeon": 全體 (jeonche, the whole), 完全 (wanjeon, complete), 安全 (anjeon, safety), 全部 (jeonbu, all), 全國 (jeon-guk, the whole country), 健全 (geonjeon, sound). It is the commonest character for "wholly, all."

Mandarin: quán, 2nd tone. 全部 (quánbù, all), 安全 (ānquán, safety), 完全 (wánquán, completely), 全国 (quánguó, the whole country), 全家 (quánjiā, the whole family). Japanese: on-reading ゼン (zen), kun まった.く (mattaku) and すべ.て (subete). 全部 (zenbu, all), 全体 (zentai, the whole), 安全 (anzen, safety), 全国 (zenkoku, nationwide), 全て (subete, all). Used daily as 全て (subete) and 全く (mattaku).

Memory aid: a flawless jade (玉) kept whole under a roof (入) — all, with nothing missing.

體 originally added 豊 (ritual vessel) to 骨 (bone) — a body furnished with bone and flesh (23 strokes). The shinjitai and simplified scripts cut it down to 体, 人 (亻, person) plus 本 (root) — and "the root of a person is the body" fits the new shape beautifully.

So the form splits: traditional (ko/en/es) is 體, shinjitai (ja) and simplified (zh) are 体 — a sharp difference in stroke count (體 23 vs 体 7).

Korean hanja-sound "che": 身體 (sinche, body), 體育 (cheyuk, physical education), 全體 (jeonche, the whole), 物體 (mulche, object), 體驗 (cheheom, experience). Korea uses the traditional 體.

Mandarin: tǐ, 3rd tone. 身体 (shēntǐ, body), 体育 (tǐyù, sports), 体验 (tǐyàn, to experience), 具体 (jùtǐ, concrete), 体重 (tǐzhòng, body weight). Japanese: on-readings タイ (tai) and テイ (tei), kun からだ (karada). 体 (karada, body), 身体 (shintai, body), 全体 (zentai, the whole), 体育 (taiiku, physical education), 体裁 (teisai, form / appearance — a テイ reading). In Japanese 物体 geminates to buttai.

Memory aid: a person (亻) whose root (本) is the body — traditional with bone (骨), shinjitai as a person's root.

Pictograph: animal footprints (the upper element) imprinted on a field (田) below. The encoded meaning: "tracks left in sequence" → "turn / order / sequence number". Identical across 繁體 / 新字体 / 简体.

番 functions as both an ordinal counter ("turn N") AND a noun "turn / sequence". It appears constantly in everyday CJK vocabulary.

Mandarin: fān, level 1st tone. 番 in modern Mandarin has shifted somewhat — it tends to mean "(coming from) foreign / barbarian" in older compounds: 番茄 (fānqié, tomato — "foreign eggplant"), 番邦 (fānbāng, foreign country, archaic). For "turn / time", Mandarin prefers 次 (cì): 一次 (yī cì, once). However 一番 (yīfān) survives meaning "a thoroughgoing / a stretch": 一番功夫 = "considerable effort". Also 番号 (fānhào, number — military / serial).

Japanese: on-reading バン (ban) is dominant and extremely high-frequency — 一番 (ichiban, "the first / number one / the most" — one of the most-used Japanese words: 一番好き = "I like X most"), 番号 (bangō, number), 当番 (tōban, on-duty turn), 順番 (junban, order / sequence), 留守番 (rusuban, house-sitter / answering machine — "keeping watch while away"), 交番 (kōban, neighborhood police box — "alternating posts", a Japanese institutional institution), 番組 (bangumi, TV/radio program — "program turn").

一番 (ichiban) is among the all-time most useful Japanese words for learners — meaning "the most" or "number one", it functions both as superlative ("the most beautiful": 一番美しい) and as ordinal ("first / #1"). 交番 (kōban, the small police kiosks scattered throughout Japanese neighborhoods) is a Japanese cultural institution worth knowing — they're where lost tourists ask for directions.

Memory aid: footprints in a field — sequential tracks → "turn" / "number".

Compound with debated etymology: 一 (one) + 白 (white). The character meant "many / numerous" in the most ancient layer, before being assigned to the specific number 100. To early speakers, 100 felt like "the largest reasonably-countable number" — the threshold beyond which counting becomes "many". Identical across 繁體 / 新字体 / 简体.

Like the smaller numbers, 百 carries a lingering "abundance / variety" sense alongside its precise numerical value. Compounds like 百姓 (common people — "the hundred surnames"), 百花 (every kind of flower), 百貨 (every kind of merchandise) all use 百 to mean "all sorts" rather than literally 100.

Mandarin: bǎi, dipping 3rd tone. 一百 (yībǎi, one hundred), 百分之 (bǎifēn zhī, "X out of 100" → percent: 百分之五十 = 50%), 百万 (bǎiwàn, million — "hundred ten-thousands"), 百货 (bǎihuò, general merchandise / department store), 老百姓 (lǎobǎixìng, "the old hundred surnames" = ordinary people / commoners — central social vocabulary), 百闻不如一见 (bǎiwén bùrú yījiàn, "hearing a hundred times is not as good as seeing once" — classic idiom).

Japanese: TWO on-readings. ヒャク (hyaku) is dominant — 百 (hyaku, 100), 百年 (hyakunen, century), 百貨店 (hyakkaten, department store — note geminate "kk"). ビャク (byaku) appears with rendaku in compounds like 三百 (sanbyaku, 300 — note voicing), 八百 (happyaku, 800 — irregular). Counting 100s in Japanese involves multiple irregular phonetic shifts: 百 hyaku, 二百 nihyaku, 三百 sanbyaku, 六百 roppyaku, 八百 happyaku — pure memorization required.

The Japanese 八百屋 (yaoya, vegetable shop) literally means "eight hundred shop" — referring to the variety of produce sold, not actual quantity.

Memory aid: 一 + 白 = the ancient symbol for "very many" → fixed at 100.

和 is a phono-semantic character: 禾 (grain) for sound and 口 (mouth) for meaning. Originally the sounds from many mouths (口) blending well — from which grew "to harmonize, to be on good terms, even, peace." It began from many voices forming an even chord.

Korean hanja-sound "hwa": 平和 (pyeonghwa, peace), 調和 (johwa, harmony), 和睦 (hwamok, concord), 和解 (hwahae, reconciliation), 溫和 (onhwa, gentle), 共和國 (gonghwaguk, republic). In East Asian thought 和 is a core value meaning concord without conflict.

Mandarin: hé, 2nd tone (to harmonize, and) / huo, neutral (to knead, warm). 和平 (hépíng, peace), 和谐 (héxié, harmony), 温和 (wēnhé, mild) / 我和你 (wǒ hé nǐ, you and I — the conjunction "and"). In modern Chinese 和 is used daily as the conjunction "and."

Japanese: on-readings ワ (wa) and オ (o), kun やわ.らぐ (yawaragu) and なご.む (nagomu). 平和 (heiwa, peace), 調和 (chōwa, harmony), 和風 (wafū, Japanese style), 和食 (washoku, Japanese cuisine), 昭和 (Shōwa). In Japan 和 (wa) came to mean "Japan itself" — 和服 (wafuku, kimono), 和室 (washitsu, a tatami room), 大和 (Yamato). 和 came to stand for Japan from rewriting the old name 倭 (Wa) with the auspicious 和.

Memory aid: the sounds of many mouths (口) blending evenly like grain (禾) — concord and peace.

世 most likely comes from three 十 (ten) joined — three tens make thirty, and reckoning one 世代 (generation) at about thirty years gave "generation, an age, the world, an era." The span of a generation passing is the world itself.

Korean hanja-sound "se": 世界 (segye, world), 世上 (sesang, the world), 世代 (sedae, generation), 世紀 (segi, century), 出世 (chulse, success in life), 別世 (byeolse, passing away), 亂世 (nanse, troubled times). With 代 seen earlier it forms 世代 (generation).

Mandarin: shì, 4th tone. 世界 (shìjiè, world), 世纪 (shìjì, century), 世代 (shìdài, generation), 去世 (qùshì, to pass away), 世故 (shìgù, worldly-wise). 世界 (shìjiè, world) is one of the most frequent everyday Mandarin words.

Japanese: on-readings セイ (sei) and セ (se), kun よ (yo). 世界 (sekai, world — a セ reading), 世紀 (seiki, century), 世間 (seken, society / the world), 出世 (shusse, success in life), 世の中 (yo no naka, the world). Japanese says 世の中 (yo no naka) and 世間 (seken) for "the world."

Memory aid: three tens (十) joined into thirty years, one generation — generations passing become the world.

Phonetic-semantic compound: 亻 (person) + 固 (firm / individual unit, providing phonetic value). The encoded meaning: "an individual unit / one by one". Three forms: 繁體 個 / 新字体 個 / 简体 个 — Mainland China simplified to a radical reduction stripping the entire left side, leaving just the bottom of 固.

Mandarin's most important measure word. 个 (gè) is the universal Mandarin classifier — when in doubt about which measure word to use for any noun, 个 works for nearly everything. This is a foundational fact every Mandarin learner must internalize on day one. It pairs with numbers and demonstratives: — 一个人 (yīgè rén, one person) — 这个 (zhège, this one — neutral final tone) — 那个 (nàge, that one) — 几个 (jǐge, how many) — 哪个 (nǎge, which one) Mandarin uses very specific measure words for many noun categories (条 for long things, 张 for flat things, 只 for animals, etc.), but 个 is the fallback that always works.

Japanese: on-reading コ (ko) — 一個 (ikko, one item — note geminate "kk"), 二個 (niko, two items), 個人 (kojin, individual person), 個性 (kosei, individuality / character), 個別 (kobetsu, individual / separate), 個数 (kosū, number of items). Japanese counting uses 個 for small round-ish objects (apples, balls, eggs); other counters apply for other shapes (枚 for flat, 本 for cylindrical, 匹 for animals, 人 for people). The Japanese counter system is famously complex — 個 covers the "default round object" category.

Note that 個人 (kojin/gèrén/個人) — "individual / private person" — is a foundational modern social-science vocabulary across CJK languages.

Memory aid: a person + something firm = an individual countable unit.

數 (traditional) is a phono-semantic character: 攴 (to tap, a hand holding a stick) for meaning and 婁 (a star name) for sound. From the action of tallying one by one came "to count, a count, number." The shinjitai and simplified reduce the left side to write 数.

So the form splits: traditional (ko/en/es) is 數, shinjitai (ja) and simplified (zh) are 数.

Korean hanja-sound "su": 數學 (suhak, mathematics), 數字 (sutja, digit), 點數 (jeomsu, score), 複數 (boksu, plural), 無數 (musu, countless), 運數 (unsu, fortune / fate). 數 also means "fate / luck" — "the 數 has run out" means one's luck is gone.

Mandarin: shù, 4th tone (number) / shǔ, 3rd tone (to count) / shuò, 4th tone (frequently). 数字 (shùzì, digit), 数学 (shùxué, mathematics), 数据 (shùjù, data), 数一数 (shǔ yī shǔ, to count). A one-character, three-sound case — "to count" is shǔ (3rd), "number" is shù (4th).

Japanese: on-readings スウ (sū) and ス (su), kun かず (kazu) and かぞ.える (kazoeru). 数 (kazu, number), 数学 (sūgaku, mathematics), 数字 (sūji, digit), 人数 (ninzū, number of people), 手数 (tesū, trouble / effort). It is the 数 you use to count pieces of sushi.

Memory aid: a hand with a stick (攴) tallying one by one — number comes from the act of counting.

記 is a phono-semantic character: 言 (speech) for meaning and 己 (self) for sound. To set speech (言) down in writing and keep it — "to record, to write down, to remember." 己 lends the sound "ji/gi."

The simplified form is 记, with 言 reduced to the speech radical 讠 — the form splits by mode.

Korean hanja-sound "gi": 記錄 (girok, record), 記憶 (gieok, memory), 日記 (ilgi, diary), 記者 (gija, reporter), 暗記 (amgi, memorization), 登記 (deunggi, registration). It is the character in a newspaper 記事 (article).

Mandarin: jì, 4th tone. 记录 (jìlù, record), 记忆 (jìyì, memory), 日记 (rìjì, diary), 记者 (jìzhě, journalist), 记得 (jìde, to remember), 笔记 (bǐjì, notes). Used constantly in daily life, as in 记不住 (jìbuzhù, can't remember).

Japanese: on-reading キ (ki), kun しる.す (shirusu). 記録 (kiroku, record), 記憶 (kioku, memory), 日記 (nikki, diary), 記者 (kisha, reporter), 暗記 (anki, memorization). It is the 記 of 古事記 (Kojiki, Japan's oldest chronicle).

Memory aid: speech (言) written down by one's own (己) hand — recording in writing what was spoken.

Compound character: 一 (one) layered on 人 (person). The encoded image: "many people, multiplied" — originally meant "a great mass of people / a thousand people in army formation", later fixed to the precise number 1,000. Identical across 繁體 / 新字体 / 简体. Like 百 (100), 千 retains a "vast quantity" sense in some compounds.

Mandarin: qiān, level 1st tone. 千 (qiān, thousand), 一千 (yīqiān, one thousand), 千万 (qiānwàn, "thousand-myriads" = ten million; also adverbial "by all means / definitely not" depending on context), 千克 (qiānkè, kilogram — "thousand grams"), 千米 (qiānmǐ, kilometer — "thousand meters"), 成千上万 (chéngqiān shàngwàn, "in their thousands and tens of thousands" — countless). Metric units in modern Mandarin uniformly use 千 as the SI thousand-prefix.

Japanese: on-reading セン (sen) — 千 (sen, 1000), 千円 (sen-en, 1000 yen — the most common Japanese banknote denomination, with Noguchi Hideyo on the front), 千年 (sennen, 1000 years / millennium), 数千 (sūsen, several thousand). Kun-reading ち (chi) appears in poetic compounds — 千鳥 (chidori, plover bird — "thousand-bird", a common motif in Japanese pottery and design), 千歳 (chitose, "thousand years" — common name and the name of the 千歳飴 chitose-ame candy given to children at 七五三 Shichi-Go-San coming-of-age festivals), 千葉 (Chiba, prefecture name — "thousand leaves"). The poetic ち reading carries elegant longevity-wishes.

Financial form: 仟 prevents alteration on contracts.

Memory aid: 一 stroke + 人 = a thousand multiplied from one person.

向 draws a window (口) in the wall of a house (宀) — originally a north-facing skylight. From which way the window faced grew "to face, direction, side." The direction of a window opened in a house is 向.

Korean hanja-sound "hyang": 方向 (banghyang, direction), 向上 (hyangsang, improvement), 傾向 (gyeonghyang, tendency), 趣向 (chwihyang, taste), 意向 (uihyang, intention), 動向 (donghyang, trend). With 方 (direction) seen earlier it forms 方向 (direction).

Mandarin: xiàng, 4th tone. 方向 (fāngxiàng, direction), 向前 (xiàngqián, forward), 一向 (yíxiàng, all along), 向往 (xiàngwǎng, to yearn for), 偏向 (piānxiàng, bias). It also works as a preposition "toward, to" — 向他学习 (to learn from him).

Japanese: on-reading コウ (kō), kun む.く (muku), む.かう (mukau), む.こう (mukō). 方向 (hōkō, direction), 向上 (kōjō, improvement), 傾向 (keikō, tendency), 向く (muku, to face), 向こう (mukō, the other side). 向かう (mukau, to head toward) is a daily Japanese essential.

Memory aid: a window (口) opened in a house (宀) and the way it faces — the direction the window points.

引 adds one straight vertical stroke (丨) to 弓 (bow) — a picture of drawing the bowstring back. From that came "to pull, to draw, to lead." The vertical is the direction in which the hand draws the string.

Mandarin: yǐn, 3rd tone. 引起 (yǐnqǐ, to give rise to), 引导 (yǐndǎo, to guide), 吸引 (xīyǐn, to attract), 引用 (yǐnyòng, to quote). 万有引力 (wànyǒu yǐnlì) is Newton's universal gravitation.

Japanese: on-reading イン (in), kun ひ.く (hiku). 引く (hiku, to pull / subtract), 割引 (waribiki, discount), 引退 (intai, retirement), 引っ越し (hikkoshi, moving house). Japanese ひく ranges widely — to pull, to lead, to look up (in a dictionary), even to catch (a cold).

Korean hanja-sound "in": 引力 (illyeok, attractive force), 引用 (inyong, citation), 割引 (harin, discount), 牽引 (gyeonin, traction). It is the character of pulling, in physics and in everyday speech alike.

Memory aid: beside the bow (弓), a straight pulling line (丨) — the force drawing the string back.

The oracle-bone 無 showed a person dancing with long feather plumes held in both hands — it was originally the ancestor of 舞 ("to dance"). When the graph was borrowed for the same-sounding word "to not have", the dance meaning split off into 舞 (with 舛, dancing feet, added below). The four dots at the bottom (灬) are not fire — they are the frozen remains of the dancer's legs and trailing sleeves.

The simplified form is 无, a revival of an ancient minimal variant that looks nothing like traditional 無. This is one of the characters whose shape diverges most sharply between scripts.

Mandarin: wú, 2nd tone. 无聊 (wúliáo, bored), 无论 (wúlùn, no matter / regardless), 无法 (wúfǎ, unable to). It is the negation that opens onto philosophy: Daoist 无为 (wúwéi, non-action), Buddhist 无常 (wúcháng, impermanence).

Japanese: on-readings ム (mu) and ブ (bu); kun な.い (nai, to not be). 無理 (muri, impossible / unreasonable), 無料 (muryō, free of charge), 無視 (mushi, to ignore). The central Zen kōan is simply 無 (mu) — "nothing", the answer that is no answer.

Korean hanja-sound "mu": 無料 (muryo, free), 無限 (muhan, infinite), 虛無 (heomu, nihility). "Not-having" is a keyword of East Asian thought.

Memory aid: the dense top is the bundle of feathers a dancer holds; the four dots below are the feet. A character borrowed from "dance" to mean "none".

算 combines 竹 (bamboo), 目 (eye), and 廾 (two hands) — bamboo (竹) above, two hands (廾) below working bamboo counting-rods watched by the eye (目). In antiquity people laid out bamboo rods (算木) to reckon numbers, and that is its core sense. The 竹 (bamboo) seen earlier sits on top.

Korean hanja-sound "san": 計算 (gyesan, calculation), 算術 (sansul, arithmetic), 豫算 (yesan, budget), 暗算 (amsan, mental arithmetic), 珠算 (jusan, abacus calculation), 算數 (sansu, arithmetic). It is the 算 of elementary-school 算數 (arithmetic).

Mandarin: suàn, 4th tone. 计算 (jìsuàn, to calculate), 打算 (dǎsuàn, to intend), 算了 (suàn le, never mind / forget it), 预算 (yùsuàn, budget), 算命 (suànmìng, to tell fortunes). 算了 (suàn le) and 打算 (dǎsuàn) are daily Mandarin essentials.

Japanese: on-reading サン (san) — essentially no kun-reading. 計算 (keisan, calculation), 算数 (sansū, arithmetic), 予算 (yosan, budget), 暗算 (anzan, mental arithmetic), 珠算 (shuzan, abacus). The 算 of the Japanese abacus (そろばん) is this.

Memory aid: bamboo (竹) counting-rods worked by two hands (廾) watched by the eye (目) — laying out rods to reckon numbers.

Another phonetic-loan etymology. Oracle bone 毎 originally pictured a woman with an adult hairpin — extending from 母 (mother), it meant "abundant / luxuriant". The character was hijacked phonetically to write the abstract adverb "every / each", and the original "abundant" sense largely faded except in classical contexts. Identical across 繁體 / 新字体 / 简体. Note Japanese sometimes simplified to 毎 with subtly different stroke proportions.

Mandarin: měi, dipping 3rd tone. 每 is one of Mandarin's most-used distributive determiners — it pairs with measure words and time units to mean "every / each": — 每天 (měitiān, every day) — 每周 (měizhōu, every week) — 每年 (měinián, every year) — 每个人 (měi gè rén, every person) — 每次 (měicì, every time) The pattern 每 + measure word + noun is grammatically essential in Mandarin.

Japanese: on-reading マイ (mai) is dominant — 毎日 (mainichi, every day — extremely high frequency, says daily newspaper "Mainichi Shimbun"), 毎週 (maishū, every week), 毎月 (maitsuki, every month), 毎年 (maitoshi, every year — irregular kun-reading hybrid), 毎晩 (maiban, every evening), 毎朝 (maiasa, every morning). The full 毎日/毎週/毎月/毎年 set is among the first calendar vocabulary Japanese learners drill.

Kun-reading ごと (goto) functions as a productive suffix meaning "each / every": 一日ごと (ichinichi goto, every day), 二人ごと (futari goto, every two people). Unlike 毎- prefixes, ごと goes after the count.

Memory aid: a mother with abundant hair — abundance reborrowed for "every".

Compound ideograph: 八 (split / divide) on top + 牛 (cow / ox) on bottom = half. The ancient farming image: a single cow divided into two equal parts. Where 分 (the previous entry) abstractly says "divide into pieces", 半 specifically encodes "divide into TWO equal halves". The 牛 has stylized over millennia until it's no longer obviously a cow, but the meaning persists. Identical across 繁體 / 新字体 / 简体.

Mandarin: bàn, falling 4th tone. 一半 (yíbàn, half — note the tone change on 一 to "yí"), 半天 (bàntiān, half a day / quite a while), 半夜 (bànyè, midnight / "half of the night"), 半价 (bànjià, half price), 多半 (duōbàn, mostly / probably). The "in the middle of doing something" sense: 半路 (bànlù, halfway), 半途而废 (bàntú érfèi, "give up halfway" — common idiom for leaving something unfinished).

Japanese: on-reading ハン (han) is dominant — 半分 (hanbun, half), 半年 (hantoshi, half a year), 三時半 (sanji-han, half past three — every Japanese time-telling lesson uses this), 半数 (hansū, half the number / majority threshold), 過半 (kahan, majority — "more than half"), 後半 (kōhan, latter half — used in sports broadcasting). Kun-reading なかば (nakaba) — 二十代なかば (nijūdai nakaba, mid-twenties), 半ば (nakaba, midway / halfway).

The Korean Peninsula 韓半島 (Hanbando / Han Bàndǎo / Kankokuhantō / Hanbando) uses 半島 to describe the geographic peninsula — "half-island", a terrain that's half land and half surrounded by sea.

Memory aid: a cow split in half — the original image of bisection.

頭 is a phono-semantic character: 頁 (head) for meaning and 豆 (bean) for sound. 頁 was originally a picture emphasizing a person's head, and 豆 lends the sound "dou/du." The topmost part of the body, the head, is its core sense.

The simplified form is greatly reduced to 头 — based on a cursive form that drops both 頁 and 豆, so it looks nothing like traditional 頭. The form splits sharply by mode.

Korean hanja-sound "du": 頭腦 (dunoe, brain), 先頭 (seondu, the lead / front), 念頭 (yeomdu, mind / thought), 龍頭 (yongdu, dragon head), 沒頭 (moldu, absorption). It is also a counter for large animals — one 頭 (du) of cattle.

Mandarin: tóu, 2nd tone (often neutral). 头 (tóu, head), 头发 (tóufa, hair), 开头 (kāitóu, beginning), 街头 (jiētóu, street corner), 一头牛 (yì tóu niú, one head of cattle). It is also a common suffix marking direction or end — 上头, 里头, 后头.

Japanese: on-readings トウ (tō) and ズ (zu), kun あたま (atama) and かしら (kashira). 頭 (atama, head), 頭脳 (zunō, brain — a ズ reading), 先頭 (sentō, the lead), 音頭 (ondo, a lead-chant), 一頭 (ittō, one animal). Large animals are counted 一頭, 二頭.

Memory aid: a head (頁) plus the sound bean (豆) — the topmost of the body, the head.

谷 shows water splitting and flowing down between mountains (the forked strokes on top) with 口 below as the valley mouth where the water drains out — the place where water runs between hill and hill, a valley. One reading sees water (水) half-sinking into the ground, only partly visible.

Mandarin: gǔ, 3rd tone. 山谷 (shāngǔ, mountain valley), 峡谷 (xiágǔ, gorge / canyon), 谷歌 (Gǔgē, the Chinese transliteration of "Google"). Note that the grain character 穀 merged into 谷 in simplified Chinese, so modern 谷 carries both "valley" and "grain" — 五谷 (wǔgǔ, the five grains).

Japanese: on-reading コク (koku), kun たに (tani). 谷 (tani, valley), 渓谷 (keikoku, ravine), 谷間 (tanima, valley floor). It is extremely common in Japanese surnames and place names — 谷 (Tani), 長谷川 (Hasegawa), 渋谷 (Shibuya, the Tokyo district).

Korean hanja-sound "gok": 溪谷 (gyegok, valley stream), 峽谷 (hyeopgok, gorge), 幽谷 (yugok, deep valley). 栗谷 (Yulgok), the pen name of the scholar Yi I, uses it too.

Memory aid: water forking down between mountains (八) toward an open mouth (口) — a valley.

玉 is three jade discs threaded on one cord — almost identical to 王 but marked off by an added dot (丶). In 王 the horizontal gaps are wider at the top; in 玉 they are even. In East Asia jade was never a mere gemstone: it was the most precious of stones, emblem of the gentleman's virtue, of purity and immortality.

Mandarin: yù, 4th tone. 玉 (yù, jade), 玉米 (yùmǐ, corn — "jade rice"), and stories like 和氏璧 (héshìbì, the jade of Mr. He). Jade often enters Chinese given names — Lín Dàiyù, the heroine of Dream of the Red Chamber, carries 玉 in her name.

Japanese: on-reading ギョク (gyoku), kun たま (tama). 玉 (tama, ball / bead), 目玉 (medama, eyeball), 十円玉 (jūendama, a ten-yen coin). In Japanese たま covers round things in general.

Korean hanja-sound "ok": 玉 (ok, jade), 珠玉 (juok, gem), 白玉 (baegok, white jade). The proverb "a flaw in the jade" treats 玉 as the very standard of perfection.

As a radical it shrinks to the 王 shape (no dot) on the left of 珠 (pearl), 球 (ball), 理 (principle — originally "to work jade along its veins").

Memory aid: 王 plus one dot — not the king (王) but the jade beads the king wears (玉).

In oracle bone script, 八 was a picture of two lines splitting apart — the original meaning was "to divide / separate". The character was reborrowed for the number eight, and the original "divide" meaning moved to 分 (= 八 + 刀, splitting with a knife). Identical across 繁體 / 新字体 / 简体.

Cultural note — the lucky number par excellence. In Mandarin, 八 (bā) sounds nearly identical to 發 / 发 (fā, "to prosper / get rich"). The pun makes 8 the most auspicious number in Chinese-speaking culture, far more powerful than 6. Real estate addresses with 8s sell at premiums; license plates with multiple 8s auction for tens of thousands of dollars; 8:08 on August 8, 2008 was the chosen start time for the Beijing Olympics opening ceremony. Phone numbers ending 8888 are luxury items. If you understand only one cultural-numerology fact about Chinese, make it this one.

In Cantonese, the pun is even stronger: 八 (baat³) and 發 (faat³) rhyme cleanly.

Mandarin: bā, level 1st tone. 八月 (bāyuè, August), 八十 (bāshí, eighty), 八卦 (bāguà, the Eight Trigrams of the I Ching — and modern slang for "gossip"), 八点 (bā diǎn, eight o'clock).

Japanese: on-reading ハチ (hachi) for everyday counting — 八月 (hachigatsu, August), 八時 (hachiji, eight o'clock), 八十 (hachijū, eighty). Kun-reading や (ya) appears in 八つ (yattsu, eight items) and the irregular date 八日 (yōka, eighth day of month).

The number is also auspicious in Japan — 八 visually opens outward, suggesting widening prosperity. The phrase 末広がり (suehirogari, "widening at the end") describes both the visual shape and the metaphorical fortune.

Financial form: 捌 prevents alteration on contracts.

Memory aid: two strokes leaning apart — the original "splitting" picture preserved exactly.

In oracle bone script, 五 was a simple X — two crossed lines, encoding "intersection" rather than literally five strokes. The X represents the meeting of opposing forces, the central balance point. Later seal-script versions added a horizontal line above and below the X, producing the modern form. Identical across 繁體 / 新字体 / 简体.

Five is mathematically and culturally central in East Asia. It is the count of the Five Phases (五行 wǔxíng / gogyō): 木 (wood), 火 (fire), 土 (earth), 金 (metal), 水 (water) — the foundational classification system that shaped Chinese medicine, cooking, color symbolism, music theory, and the names of weekdays. Other "five" concepts: 五感 (five senses), 五味 (five tastes: sweet/sour/salty/bitter/spicy), 五穀 (five grains), 五倫 (five Confucian relationships).

Mandarin: wǔ, dipping 3rd tone. 五月 (wǔyuè, May), 五十 (wǔshí, fifty), 五星 (wǔxīng, five stars — as on the Chinese flag, 五星红旗). The number is considered neutral-to-lucky.

Japanese: on-reading ゴ (go) for everyday counting — 五月 (gogatsu, May), 五人 (gonin, five people), 五分 (gofun, five minutes). Kun-reading いつ (itsu) survives in 五日 (itsuka, fifth day of month — irregular but high-frequency) and 五つ (itsutsu, five items). The ゴ shorthand became the brand name "Go" for the board game (originally 碁).

Financial form: 伍 prevents alteration on contracts. Note that 伍 is also a common surname in Chinese.

Memory aid: an X-shaped intersection between two horizontal lines — top and bottom limits with crossing in the middle.

The point where the pictographic number system gives up. Oracle bone forms originally drew "four" as four horizontal lines (亖), but the parallel-stroke system became unreadable past three, so scribes invented a new shape: a rectangle with a divider inside, suggesting four enclosed quadrants. Identical across 繁體 / 新字体 / 简体.

Cultural caution — the unlucky number. In Mandarin, 四 (sì, falling tone) sounds nearly identical to 死 (sǐ, dying tone — death). In Japanese, 四 (shi) is identical in pronunciation to 死 (shi, death). This phonetic coincidence makes 4 the East Asian equivalent of Western 13. Hospitals and hotels in China, Korea, and Japan routinely skip floor 4. Phone numbers and license plates avoid 4. Gift counts of four are taboo. Knowing this is essential for visitors and learners — never give a gift in fours.

This is also why Japanese has TWO readings for 4: シ (shi, on-reading) and よん (yon, kun-reading reborrowed from native Japanese). Whenever the unlucky シ would feel awkward, speakers switch to よん: 四階 reads よんかい (yonkai, fourth floor), 4時 reads よじ (yoji, four o'clock — note: not yon-ji), 4人 reads よにん (yonin). Pure compounds like 四月 (shigatsu, April) keep シ.

Mandarin: sì, falling 4th tone. 四月 (sìyuè, April), 四方 (sìfāng, four directions), 四季 (sìjì, four seasons), 四川 (Sìchuān, Sichuan province — "four rivers"), 四十 (sìshí, forty).

Financial form: 肆 prevents alteration on contracts.

Memory aid: a square box with two interior strokes — four quadrants enclosed.

In oracle bone script, 九 originally pictured a bent arm at the elbow — the meaning was "elbow / bent". Phonetic loan repurposed it to write the number nine, and the body part eventually moved to 肘 (elbow). The hooked stroke in modern 九 still traces the bent-elbow shape. Identical across 繁體 / 新字体 / 简体.

Cultural note — the imperial number. As the largest single digit before rolling over to 10, 九 traditionally represents "the maximum / complete / supreme". Imperial Chinese architecture is saturated with 9: the Forbidden City has 9,999 rooms by tradition, the gates have door-knobs in 9×9 = 81 grids, the imperial robes were embroidered with nine dragons. 九重 (jiǔchóng, "ninefold") was a synonym for the imperial palace. The Mandarin homophone with 久 (jiǔ, "long-lasting") strengthens the auspicious sense — wedding gifts of 99 or 999 wish the couple "long love".

In Japanese, 九 has the opposite cultural valence: the on-reading ク (ku) is identical to 苦 (ku, "suffering"), making 9 mildly inauspicious. Some hospitals avoid room number 9. This split — auspicious in China, inauspicious in Japan — is one of the cleanest examples of how the same character carries different cultural weight across the CJK sphere.

Mandarin: jiǔ, dipping 3rd tone. 九月 (jiǔyuè, September), 九十 (jiǔshí, ninety), 九尾狐 (jiǔwěihú, nine-tailed fox — the kitsune-yokai of East Asian folklore).

Japanese: on-readings キュウ (kyū) — 九月 (kugatsu, September — note: irregular reading shifts to ku!), 九時 (kuji, nine o'clock), 九人 (kyūnin, nine people). Kun-reading ここの (kokono) in 九つ (kokonotsu, nine items), 九日 (kokonoka, ninth day of month — high-frequency irregular). The double readings are pure pain for learners.

Financial form: 玖 prevents alteration.

Memory aid: a hooked stroke + diagonal — a bent arm reduced to two strokes.

One single horizontal stroke. The most economical possible character — and one of six "indicative" characters (指事字 / zhǐshìzì) where a stroke directly indicates a concept rather than picturing a thing. Identical across 繁體 / 新字体 / 简体.

Despite its visual simplicity, 一 carries a wide semantic load. Beyond "one", it means "first / unified / whole / same / once". 第一 (dìyī, first), 统一 (tǒngyī, unified), 一样 (yīyàng, same), 一起 (yīqǐ, together), 一切 (yīqiè, everything), 一边 (yībiān, one side / while). The expansion from "one" to "everything" passes through "unity".

Mandarin: yī, level 1st tone in citation form — but 一 has the unusual property of tone-sandhi: it shifts to falling 4th tone (yì) before 1st/2nd/3rd tone syllables, and to rising 2nd tone (yí) before 4th tone syllables, but stays 1st tone when ordinal or alone. So 一个 reads yīgè in counting but yìgè in ordinary speech. This is one of the first "advanced" pronunciation rules Mandarin learners must internalize.

Japanese: on-readings イチ (ichi) for counting and ordinals — 一月 (ichigatsu, January), 一人 (one person... but read ひとり / hitori — irregular!), 第一 (daiichi, first); イツ (itsu) in 統一 (tōitsu, unification), 同一 (dōitsu, identical). Kun-reading ひと (hito) survives only in compounds like 一つ (hitotsu, one item) and 一人 (hitori, one person) — both irregular but high-frequency.

Writing tip: in formal/financial contexts, 一 is often replaced by 壹 (the formal banker's form) on checks and contracts to prevent forgery — adding strokes to a horizontal line to read "two" or "three" is too easy.

Memory aid: a single line. The picture is the meaning.

In oracle bone script, 七 was a plus sign — a vertical stroke crossed by a horizontal one — and meant "to cut / cleave". The character was repurposed phonetically to write the number seven, and a new character 切 (still meaning "cut") was created later by adding 刀 (knife) to the original. So 七 is a fossilized loan: a knife symbol used for an unrelated number. The bottom hook in modern 七 is a stylized cut-mark. Identical across 繁體 / 新字体 / 简体.

Seven carries mixed cultural weight. The constellation 北斗七星 (Big Dipper / Plough — "Northern Bushel Seven Stars") is a navigational and divination focus across East Asia. The 七夕 (qīxī / tanabata) festival on the seventh day of the seventh lunar month celebrates the once-yearly meeting of two star-crossed lovers (the Cowherd and the Weaver Girl) — basically the East Asian Valentine's Day. In Buddhist tradition, the soul wanders for 49 days (7×7) after death.

Mandarin: qī, level 1st tone. 七月 (qīyuè, July), 七十 (qīshí, seventy). Number 7 is generally considered slightly lucky in Mandarin-speaking culture — not as auspicious as 6 or 8, but positive.

Japanese: on-reading シチ (shichi) — but again the dual-reading rule kicks in to avoid death-syllable confusion (シ in シチ shares the death sound). Many speakers use kun-reading なな (nana) for clarity: 七時 reads either しちじ (shichiji) or ななじ (nanaji); 七人 (shichinin or nananin). 七つ (nanatsu, seven items). This dual-reading habit, born of cultural caution, is one of the genuinely difficult parts of Japanese number-fluency.

Financial form: 漆 (also lacquer/paint character — homograph).

Memory aid: a horizontal line crossed by a hooked vertical — the original cut mark, repurposed.

Etymology of 六 is uncertain — competing theories include a small dwelling viewed from the side, or a hand showing six fingers (thumb extended at angle). What is clear: by oracle bone times the character was already a phonetic loan, not a counting picture. Identical across 繁體 / 新字体 / 简体.

Cultural note — the lucky number. In Mandarin, 六 (liù) sounds nearly identical to 流 (liú, "to flow"), and the phrase 六六大顺 (liù liù dà shùn) means "everything flows smoothly". So 6 is considered very lucky in Chinese-speaking cultures — the opposite of 4. Phone numbers, license plates, and addresses ending in 6 carry premium prices. Six and 8 (also lucky) often appear in business naming.

Mandarin: liù, falling 4th tone. 六月 (liùyuè, June), 六十 (liùshí, sixty), 星期六 (xīngqīliù, Saturday — "sixth day of the week"). The Mandarin number-week system runs Mon=1 through Sat=6, with Sunday using 日 (rì) instead of "7" — a learner trap.

Japanese: on-reading ロク (roku) for everyday counting — 六月 (rokugatsu, June), 六時 (rokuji, six o'clock). Watch out — when counting people, 六人 reads ろくにん (rokunin), but for ordinal day-of-month, 六日 reads むいか (muika, sixth day) — irregular kun-form.

Kun-reading む (mu) shows up in 六つ (muttsu, six items) and the irregular dates above. Like 4, the kun-readings of low numbers are essential for fluency.

Financial form: 陸 prevents alteration. Note: this same character means "land" in normal use — the financial form is a homograph.

Memory aid: a roof with two legs underneath. Hard to mnemonic — most learners just memorize the shape.

In oracle bone script, 十 began as a single vertical stroke — a "bundle of ten" condensed into one mark. Later seal-script scribes added a horizontal crossbar to disambiguate it from 一 rotated 90°, producing the cross-shape we use today. Identical across 繁體 / 新字体 / 简体.

Ten is the rollover point of the base-10 system, and CJK culture treats it as the symbol of "complete, full, perfect": 十全 (shíquán, complete), 十分 (shífēn / jūbun, "ten parts" = thoroughly / sufficient), 十全十美 (shíquán shíměi, "ten-perfect ten-beautiful" = absolutely flawless), 十中八九 (shízhōng bājiǔ, "eight or nine out of ten" = highly likely). The number sits at the boundary where digits exhaust and place-value begins — and the small cross + carries that conceptual closure.

Mandarin: shí, rising 2nd tone. 十月 (shíyuè, October), 十分 (shífēn, very / completely), 十年 (shínián, ten years / a decade), 二十 (èrshí, twenty), 十字路口 (shízì lùkǒu, "ten-character intersection" = crossroads — because 十 looks like a +).

Japanese: on-reading ジュウ (jū) for everyday counting — 十月 (jūgatsu, October), 十時 (jūji, ten o'clock), 十人 (jūnin, ten people), 十分 (jūbun, sufficient — careful: 十分 also reads じっぷん/jippun for "ten minutes", same kanji different meaning). Less common ジッ (ji-) before voiceless sounds. Kun-reading とお (tō) in 十 (tō, ten) and 十日 (tōka, tenth day of month — irregular but high-frequency).

The character also serves as a cross — a Christian cross is 十字架 (shízìjià / jūjika, "ten-character frame"). The Japanese Red Cross is 日本赤十字社 (Nihon Sekijūjisha).

Financial form: 拾 prevents alteration. Note: this same character means "to pick up" in normal use — a homograph.

Memory aid: a + sign. A vertical bundle crossed by horizontal authority — ten in two strokes.

Three horizontal strokes — the last "obvious" number. The pictographic counting series breaks at 四: from 4 onward, characters use phonetic loans rather than continuing to add lines (otherwise 9 would be a tangle of strokes nobody could read). Identical across 繁體 / 新字体 / 简体.

Three carries cultural weight across East Asia. The number is associated with completeness and stability: 三才 (sāncái, "the Three Talents" — Heaven, Earth, and Humanity, the foundational Confucian cosmology), 三國 / 三国 (Three Kingdoms — the iconic 3rd-century period dramatized in 三国志 / Sangokushi / Romance of the Three Kingdoms), 三十六計 (Thirty-Six Strategies, classical Chinese strategy text). Buddhist 三宝 (Three Treasures: Buddha, Dharma, Sangha). Three is "enough but not excess" — the natural rest point.

Mandarin: sān, level 1st tone. 三月 (sānyuè, March), 三角 (sānjiǎo, triangle), 三明治 (sānmíngzhì, sandwich — phonetic loan: "san-ming-zhi"). The same tone as 山 (mountain), but shorter syllable and very different rhyme.

Japanese: on-reading サン (san) is identical to 山 — context disambiguates. 三月 (sangatsu, March), 三角形 (sankakkei, triangle), 三人 (sannin, three people — note this one is regular, unlike 二人/futari). Kun-reading み (mi) survives in 三日 (mikka, third day of month — irregular but common) and 三つ (mittsu, three items).

Financial form: 参 (also written 參) prevents forgery on financial documents. Adding two strokes to 三 to make 五 was historically too easy.

Memory aid: three lines stacked, with the middle line slightly shorter (calligraphic convention).

Two horizontal strokes. A direct extension of 一 by adding one more line. Identical across 繁體 / 新字体 / 简体.

Mandarin: èr, falling 4th tone. But here is one of the first counter-intuitive rules of Mandarin: when counting two of something with a measure word, Mandarin replaces 二 with 兩 / 两 (liǎng): 两个人 (liǎng gè rén, two people) — not 二个人. The pattern: use 二 for ordinal numbers and pure counting (二月, February; 第二, second), but 两 (or 兩) when "two of [things]" with a classifier. Japanese and Korean keep 二 in both situations, so this is a Mandarin-specific rule learners must memorize early.

2 also means "ordinal second" without 第 prefix in many Asian contexts: 二院 (the Senate / second house), 二流 (second-rate), 二战 (èrzhàn, World War II — abbreviation of "Second World War").

Japanese: on-readings ニ (ni) for everyday counting — 二月 (nigatsu, February), 二人 (futari... wait, irregular!), 二日 (futsuka, second day of month — irregular kun-reading); ジ (ji) in formal compounds like 二次会 (nijikai, after-party — "second meeting"). The kun-reading ふた (futa) shows up in 二つ (futatsu, "two items") and 二人 (futari, "two people") — these are high-frequency irregular readings.

Financial form: 弐 (also written 貳) replaces 二 on Japanese checks and Chinese contracts to prevent forgery (you cannot easily turn 弐 into 参 the way you could turn 二 into 三).

Memory aid: two lines, top shorter than bottom (Chinese convention) or equal length (Japanese convention).
