The characters, one by one
見jiàn · ケンsee
Compound ideograph: 目 (eye) on top + 儿 (a person, the legs-radical) below. The encoding is "a person with their eye emphasized" — the act of seeing personified. Three forms: 繁體 見 / 新字体 見 / 简体 见.
Mandarin: jiàn, falling 4th tone. The Mandarin everyday verb for "to look" is 看 (kàn), but 见 dominates two crucial domains: completion ("to perceive / to have seen") and meeting people. 看见 (kànjiàn, "to look-see" = perceived/saw it), 听见 (tīngjiàn, to hear / perceive sound), 见面 (jiànmiàn, to meet face-to-face), 再见 (zàijiàn, "see you again" = goodbye — every Mandarin learner's first farewell), 意见 (yìjiàn, opinion), 不见 (bùjiàn, missing / not seen).
Note: in Mandarin, the perception verbs 看 (look) and 见 (perceive) split labor — 看 is the active gaze, 见 is the result of perception. 看见 means "looked AND saw"; just 看 might mean "looked but didn't notice".
Japanese: on-reading ケン (ken) for compounds — 意見 (iken, opinion), 発見 (hakken, discovery), 見学 (kengaku, school visit / observation tour), 会見 (kaiken, formal meeting / press conference), 偏見 (henken, prejudice). Kun-readings divide labor among related verbs: — み.る (mi.ru, to see) — basic everyday verb. 見る. — み.える (mi.eru, to be visible / appear) — passive/spontaneous. 見える. — み.せる (mi.seru, to show) — causative. 見せる. The trio 見る / 見える / 見せる is one of the foundational verb-relationship sets in Japanese — active, passive, causative.
Memory aid: an oversized eye on legs — perception walking the world.
- 見るみるto see
- 意見いけんopinion
- 発見はっけんdiscovery
- 看见kànjiànto see
- 见面jiànmiànto meet
- 再见zàijiàngoodbye
合hé · ゴウ · ガッ · カッfit
合 shows a lid (亼) closing snugly over a vessel (口) — the top is the meeting lid, the 口 below is the vessel's mouth. From a lid fitting a vessel exactly came "to fit, to match, to join, to gather."
Korean hanja-sound "hap": 合計 (hapgye, total / sum), 結合 (gyeolhap, combination), 合格 (hapgyeok, passing an exam), 組合 (johap, union / cooperative), 集合 (jiphap, a set / gathering). There is also a special use where 合 writes the volume unit "hop" (one-tenth of a doe), read not "hap" but "hop."
Mandarin: hé, 2nd tone. 合作 (hézuò, to cooperate), 合适 (héshì, suitable), 适合 (shìhé, to suit), 合同 (hétong, contract). It also means "to close / put together" — 合上 (héshàng, to close).
Japanese: on-readings ゴウ (gō), ガッ (ga'), カッ (ka'), kun あ.う (au) and あ.わせる (awaseru). 合う (au, to match), 試合 (shiai, a match / game), 合格 (gōkaku, passing), 合体 (gattai, merging), 都合 (tsugō, circumstances). It geminates to ガッ/カッ before some characters — 合戦 (kassen, battle), 合宿 (gasshuku, a training camp).
Memory aid: a lid (亼) snug on a vessel (口) — two parts fitting exactly into one.
- 試合しあいmatch, game
- 都合つごうcircumstances
- 合作hézuòto cooperate
- 适合shìhéto suit
表biǎo · ヒョウsurface
表 combines 毛 (fur) and 衣 (clothing) — originally the "outer side" of a fur garment (衣) with the fur (毛) on the outside. From the outside of clothing grew "surface, outside, to show, to express," and the organized "table / chart." The 衣 (clothing) splits top and bottom with 毛 between.
Korean hanja-sound "pyo": 表面 (pyomyeon, surface), 表現 (pyohyeon, expression), 發表 (balpyo, announcement), 代表 (daepyo, representative), 圖表 (dopyo, chart), 時間表 (siganpyo, timetable). All three branches — "surface," "to express," and "table" — live on.
Mandarin: biǎo, 3rd tone. 表面 (biǎomiàn, surface), 表示 (biǎoshì, to indicate), 表演 (biǎoyǎn, to perform), 手表 (shǒubiǎo, wristwatch), 代表 (dàibiǎo, representative), 表格 (biǎogé, a form / table). In modern Chinese a wristwatch is 手表 (shǒubiǎo).
Japanese: on-reading ヒョウ (hyō), kun おもて (omote) and あらわ.す (arawasu). 表面 (hyōmen, surface), 発表 (happyō, announcement), 表 (omote, the front / outside), 表情 (hyōjō, facial expression), 時刻表 (jikokuhyō, timetable). Japanese 表 (omote, front) pairs with 裏 (ura, back).
Memory aid: fur (毛) between clothing (衣) — from the outer side of a fur garment to surface, expression, and table.
- 発表はっぴょうannouncement
- 表情ひょうじょうfacial expression
- 表面biǎomiànsurface
- 手表shǒubiǎowristwatch
題tí · ダイtopic
題 is a phono-semantic character: 頁 (head) for meaning and 是 (right) for sound. 頁 means head or forehead, and the "forehead" of a text is its title — from which grew "title, heading, topic, question." It shares the 頁 (head) radical with 頭 seen earlier.
The simplified form is 题, with 頁 reduced to the simplified head 页 — the form splits by mode.
Korean hanja-sound "je": 題目 (jemok, title), 問題 (munje, problem / question), 主題 (juje, theme), 宿題 (sukje, homework), 話題 (hwaje, topic of talk), 課題 (gwaje, task), 出題 (chulje, setting exam questions). It is the character in school 宿題 (homework) and exam 出題.
Mandarin: tí, 2nd tone. 问题 (wèntí, problem / question), 题目 (tímù, title), 主题 (zhǔtí, theme), 话题 (huàtí, topic), 标题 (biāotí, headline), 难题 (nántí, a hard problem). 问题 (wèntí, problem) is one of the most frequent everyday Mandarin words.
Japanese: on-reading ダイ (dai) — no kun-reading (on-only). 題 (dai, title), 問題 (mondai, problem), 宿題 (shukudai, homework), 話題 (wadai, topic), 主題 (shudai, theme), 題名 (daimei, title). A Japanese student's 宿題 (shukudai, homework) carries this character.
Memory aid: a head (頁) plus right (是) — the forehead of a text, hence title and question.
- 問題もんだいproblem
- 宿題しゅくだいhomework
- 问题wèntíproblem
- 题目tímùtitle
聞wén · ブン · モンhear
Compound ideograph: 門 (gate / door) on the outside + 耳 (ear) inside. Picture: someone leaning against a closed gate, ear pressed to the wood, listening to what's happening outside. The verb of "hearing" frozen into a domestic scene. Three forms: 繁體 聞 / 新字体 聞 / 简体 闻.
Watch out for a fascinating cross-language semantic split that learners must absorb: — Japanese: 聞 means almost exclusively "to hear / listen". The Japanese verb for "to smell" is 嗅ぐ (kagu, written with a different character). — Mandarin: 闻 has shifted in everyday use to mean "to smell". The Mandarin verb for "to hear" is 听 (tīng — a different character entirely). 闻 still means "to hear" in formal/written Chinese (闻名 = "famous", literally "having one's name heard"), but in spoken Chinese, 闻 will usually be interpreted as "smell/sniff": 闻闻这个 (wénwén zhège) = "smell this". This means the SAME character covers different sense-verbs in different languages — a classic CJK false friend trap.
Mandarin: wén, rising 2nd tone. 新闻 (xīnwén, news), 闻名 (wénmíng, famous), 听闻 (tīngwén, to hear about — formal). And smell-meanings: 闻一闻 (wén yī wén, to take a sniff).
Japanese: on-reading ブン (bun) for compounds — 新聞 (shinbun, newspaper — every Japanese household), 見聞 (kenbun, things seen and heard / experience), 風聞 (fūbun, hearsay / rumor). Less common モン (mon) in older compounds. Kun-readings: き.く (ki.ku) — to hear / listen / ask. The dual meaning "to hear" and "to ask" is essential — 聞いてもいい? = "Can I ask?", 音楽を聞く = "to listen to music", 雨の音を聞く = "to hear the sound of rain". き.こえる (ki.koeru, to be audible / to be heard).
Memory aid: an ear inside a closed gate — listening for what comes through.
- 新聞しんぶんnewspaper
- 聞くきくto hear / to ask
- 聞こえるきこえるaudible
- 新闻xīnwénnews
- 闻名wénmíngfamous
- 听闻tīngwénto hear about
首shǒu · シュneck
首 is one of the oldest pictographs in the language: the oracle bone draws a human head with hair and a single staring eye. Three meanings collapse into one sign — head, neck, and "the foremost / chief." Anything that sits at the top of something — a leader, a capital city, even the count of a song — pulls the same character.
Korean reading "su." 首都 (sudo, capital city), 首席 (suseok, top rank / valedictorian), 首相 (susang, prime minister), 元首 (wonsu, head of state), 首肯 (sugung, "to nod the head" = to agree), 首尾 (sumi, "head and tail" = beginning and end of an affair). Korean retains the abstract "foremost" sense of 首 powerfully — almost any "top X" official title in Korean uses this character.
Mandarin shǒu, 3rd tone. 首都 (shǒudū, capital), 首先 (shǒuxiān, first of all), 首席 (shǒuxí, chief / principal), 一首歌 (yì shǒu gē, "one song"). Mandarin uniquely uses 首 as a measure word for songs, poems, and short literary works — a grammatical role you will not find for the same character in Korean or Japanese.
Japanese on-reading シュ (shu) — 首相 (shushō, prime minister), 首都 (shuto, capital), 元首 (genshu, head of state). Kun-reading くび (kubi) — and here the meaning narrows: in modern Japanese, 首 means specifically "neck," not "head." 首が痛い (kubi ga itai) = "my neck hurts." Japanese also turns 首 into the everyday idiom 首にする (kubi ni suru, "to make their head [come off]") meaning "to fire someone from a job" — a vivid trace of Japan's feudal vocabulary surviving in modern HR slang.
Memory aid: a head with hair and one eye drawn together — the topmost part of the body, then "topmost" of anything.
- 首くびneck
- 首相しゅしょうprime minister
- 首都しゅとcapital
- 首都shǒudūcapital
- 首先shǒuxiānfirst of all
- 一首歌yì shǒu gēa song
顏yán · ガンface
Phonetic-semantic compound: 頁 (head — the right-side radical, 9 strokes) + 彦 (an "elegant person", phonetic). The encoded meaning: "the most expressive part of a head" → face / countenance. Three forms: 繁體 顏 / 新字体 顔 / 简体 颜 (Mainland China simplified the head radical 頁 to 页).
Critical CJK divergence on this character's primary modern meaning: — Korean / Japanese: 顔 / 顏 means "face" — the everyday word for one's face. — Mandarin: 颜 in modern usage shifted toward "color" — appearing in 颜色 (yánsè, "color"), the standard Mandarin word for color (already discussed in 色 entry). For "face", modern Chinese uses 脸 (liǎn) — a different character. So the same character that means "face" in Japan/Korea means "color" in China for everyday speech.
Mandarin: yán, rising 2nd tone (simplified 颜). 颜色 (yánsè, color), 颜面 (yánmiàn, face / dignity — formal), 容颜 (róngyán, appearance / countenance — literary), 颜值 (yánzhí, "face-value" → physical attractiveness — modern slang term, very popular in social media).
The modern Chinese slang 颜值 (yánzhí, "face value" — beauty rating) emerged in the 2010s and has become ubiquitous on Chinese social media: 颜值高 = "high face value" (good looking), 颜值党 = "the beauty party" (fans of attractive celebrities).
Japanese: on-reading ガン (gan) for compounds — 顔面 (ganmen, face / facial). Kun-reading かお (kao) is the everyday word — 顔 (kao, face), 笑顔 (egao, smiling face), 顔色 (kaoiro, complexion — note same compound as Mandarin 颜色 but pronounced kun-reading and meaning "complexion"), 寝顔 (negao, sleeping face), 似顔絵 (nigaoe, portrait drawing).
笑顔 (egao, "smiling face") is one of the warmest words in everyday Japanese — used constantly in advertisements, songs, and personal messages to express emotional warmth.
Memory aid: head + elegance = the face we present to the world.
- 顔かおface
- 笑顔えがおsmiling face
- 顔色かおいろcomplexion
- 颜色yánsècolor
- 颜面yánmiànface
髮fà · ハツhair
Phonetic-semantic compound: 髟 (the "long hair / mane" radical, depicting flowing hair) + 犮 (an old form of 友, providing phonetic value). The encoded meaning: "long flowing hair" → hair on the head. Three forms with significant simplification: 繁體 髮 / 新字体 髪 / 简体 发.
Critical Mainland Chinese complication: simplified Chinese MERGED two unrelated characters into 发. The traditional 髮 (hair, fà 4th tone) and 發 (to send / develop, fā 1st tone) both became 发 in simplified script. So the same 发 character carries TWO completely different meanings, distinguished only by tone: 发 fā (issue / develop) vs. 发 fà (hair). Mainland Chinese learners must absorb this — Hong Kong / Taiwan / Japan still distinguish the two characters visually.
Mandarin: fà, falling 4th tone (simplified 发, the hair-meaning). 头发 (tóufa, hair on head — neutral final tone), 理发 (lǐfà, to cut hair / get a haircut), 染发 (rǎnfà, to dye hair), 长发 (chángfà, long hair), 白发 (báifà, white / gray hair). Note 头发 (tóufa) — "head-hair" — is the everyday word; 髮 alone feels formal.
Japanese: on-reading ハツ (hatsu) for compounds — 散髪 (sanpatsu, haircut), 白髪 (hakuhatsu, white hair), 金髪 (kinpatsu, blonde hair). Kun-reading かみ (kami) is the everyday word — 髪 (kami, hair), 髪型 (kamigata, hairstyle), 髪の毛 (kami no ke, hair strand). Note this kun-reading かみ is identical to the kun-reading for 神 (god) and 紙 (paper) — three meaningful homophones distinguished only by kanji.
危機一髮 (kiki ippatsu, "crisis by a single hair") is a famous four-character idiom — "by a hair's breadth" / "narrow escape".
Memory aid: long flowing hair radical — the locks on a head.
- 髪かみhair
- 散髪さんぱつhaircut
- 头发tóufahair
- 理发lǐfàhaircut
齒chǐ · シtooth
Pictograph: an open mouth showing teeth in upper and lower rows. Oracle bone forms display the teeth grid clearly. Three forms with substantial divergence: 繁體 齒 / 新字体 歯 / 简体 齿. Both Japan and Mainland China simplified, but went separate directions — another case where reading across CJK scripts requires knowing all three forms.
Note 齒 (teeth) is distinguished from 牙 (fang / molar — earlier batch) — 齒 covers the front teeth visible when smiling; 牙 is the rear molars / animal fangs. In everyday speech the distinction blurs but it's real in formal vocabulary.
Mandarin: chǐ, dipping 3rd tone (simplified 齿). 牙齿 (yáchǐ, "teeth" — combines 牙 + 齿 for the everyday word), 齿轮 (chǐlún, gear / cog — "tooth wheel"), 切齿 (qièchǐ, gnash one's teeth). Modern Mandarin tends to use 牙 alone for casual "teeth" and 牙齿 for the formal compound; 齿 alone appears in literary or technical contexts.
Japanese: on-reading シ (shi) for compounds — 歯科 (shika, dentistry), 歯科医 (shikai, dentist), 永久歯 (eikyūshi, permanent teeth), 乳歯 (nyūshi, baby teeth), 義歯 (gishi, dentures). Kun-reading は (ha) is the everyday word — 歯 (ha, tooth), 歯医者 (haisha, dentist), 虫歯 (mushiba, cavity / tooth decay — "bug-tooth"), 歯磨き (hamigaki, toothbrush / brushing teeth — "tooth-polish"). 歯ブラシ (haburashi, toothbrush) uses katakana for "brush".
虫歯 (mushiba, "bug-tooth" = cavity) is one of the most charmingly literal Japanese compounds — every Japanese child encounters this word during dental hygiene lessons.
Memory aid: a mouth showing rows of teeth — the picture is the meaning, simplified across three scripts.
- 歯はtooth
- 歯科しかdentistry
- 虫歯むしばcavity
- 牙齿yáchǐtooth
- 齿轮chǐlúngear
舌shé · ゼツtongue
Pictograph: a tongue extending from a mouth (口 at the bottom). Oracle bone forms show the forked tip of the tongue extending upward — the character is the picture. Identical across 繁體 / 新字体 / 简体. Note 舌 is distinct from but related to 言 (speech, from earlier batch) — 言 is "what comes out of a mouth", 舌 is the organ that produces it.
Mandarin: shé, rising 2nd tone. 舌头 (shétou, tongue — the everyday word, neutral final tone), 舌尖 (shéjiān, tip of tongue — also the title of a famous Chinese food documentary 舌尖上的中国, "A Bite of China"), 口舌 (kǒushé, tongue and mouth → speech / argument). The compound 唇齿相依 (chúnchǐ xiāngyī, "lips and teeth depend on each other") expresses interdependence.
Japanese: on-reading ゼツ (zetsu) for compounds — 舌戦 (zessen, war of words), 毒舌 (dokuzetsu, sharp / poisonous tongue — used to describe a comedian who roasts others), 弁舌 (benzetsu, eloquence). Kun-reading した (shita) is the everyday word — 舌 (shita, tongue), 舌打ち (shitauchi, clicking the tongue in irritation — culturally significant gesture), 舌足らず (shitatarazu, lisp / inarticulate).
The character's phonetic role is significant — when 舌 sits on the right side of compounds it often carries a "she/zetsu/setsu" sound, leading to characters like 話 (speech, 言+舌), 活 (alive, 氵+舌), 適 (suitable). Recognizing 舌 as a phonetic component helps decode many derived characters.
The Japanese 毒舌 (dokuzetsu, "poison tongue") is positively used to describe stand-up comedians and roasters whose sharp humor is appreciated.
Memory aid: a tongue sticking out of a mouth — the most direct possible picture.
- 舌したtongue
- 舌打ちしたうちclicking the tongue
- 舌头shétoutongue
- 舌尖shéjiāntip of tongue
耳ěr · ジear
耳 traces the side profile of an ear — the outer pinna and its inner ridges visible in the strokes. Identical across 繁體 / 新字体 / 简体. The character is one of the cleanest pictographs to memorize because the picture has not faded.
耳 builds a small but vivid family of compound characters around hearing. The most beautiful is 聞 (to hear): 門 (gate) + 耳 (ear) — someone leaning at a gate, ear pressed close, listening for sounds outside. The verb is encoded as a scene. Other compounds: 聖 (holy/sage — ear + mouth + standing person, the wise listener), 聴 (to listen attentively), 聲 (voice — the simplified form 声 hides this etymology), 取 (to take — hand grasping ear, recalling an ancient battlefield trophy custom).
Mandarin: ěr, dipping 3rd tone. 耳朵 (ěrduo) is the everyday word for ear; 耳机 (ěrjī) is headphones; 耳环 (ěrhuán) is earrings; 耳鸣 (ěrmíng) is tinnitus. The classical literary 耳 also functioned as a final particle in Classical Chinese ("merely / that is all") — modern readers see this only in citations.
Japanese: on-reading ジ (ji) is rare on its own, mostly in compounds — 耳鼻科 (jibika, ENT clinic). The kun-reading みみ (mimi) is everyday — 耳 (mimi, ear), 早耳 (hayamimi, "fast ear" — someone quick to pick up news), 耳が痛い (mimi ga itai, "my ears hurt" — said when criticism strikes home).
Memory aid: a vertical rectangle with horizontal ridges — outer ear seen from the side. Where 目 rotates a horizontal eye to vertical, 耳 keeps the natural side-view orientation.
- 耳鼻科じびかENT clinic
- 耳元みみもとclose to the ear
- 耳朵ěrduoear
- 耳机ěrjīheadphones
目mù · モク · ボクeye
目 is a horizontal eye in oracle bone form — pupil, eyelid, and outer rim drawn flat. Later scribes rotated it 90° vertical to fit the standardizing column-grid of the seal script, giving the upright shape used today. Identical across 繁體 / 新字体 / 简体.
As a radical, 目 marks anything seen, watched, or evaluated: 看 (to look — a hand shielding the eye), 見 (to see), 直 (straight — the eye sees true), 真 (truth/real), 相 (mutual / phase — eye facing tree), 眠 (sleep — eye + people), 督 (supervise — eye scrutinizing), 盲 (blind — eye lost), 自 (self — originally a nose, but visually a stretched eye). When you see 目 inside a character, expect vision, observation, or assessment.
Mandarin: mù, falling 4th tone. 目 alone feels formal in modern Chinese; everyday "eye" is 眼睛 (yǎnjing). But 目 dominates compound vocabulary: 目标 (mùbiāo, goal/target), 目录 (mùlù, table of contents), 题目 (tímù, topic/question), 节目 (jiémù, program/show), 引人注目 (yǐn rén zhù mù, "to attract attention"), 一目了然 (yī mù liǎo rán, "clear at a single glance").
Japanese: on-reading モク (moku) in 注目 (chūmoku, attention), 目的 (mokuteki, purpose), 目次 (mokuji, table of contents). Less common ボク (boku) in 面目 (menboku, face/honor). The kun-reading め (me) is the everyday word — 目 (me, eye), 目薬 (megusuri, eyedrops), 目覚まし (mezamashi, alarm clock — "eye-waker"), and ordinal counter for items in sequence (一つ目, "the first one").
Memory aid: rotated 90° from a horizontal eye. The two interior strokes are pupil and rim.

- 目的mùdìpurpose

首shǒu · シュhead
首 combines hair (巛 — three wavy strokes on top, suggesting locks of hair) with face (自 — originally the nose-pictograph from the 鼻 entry). Together: hair-on-face = head. The metaphor expands naturally to "leader / first / chief" — a head leads a body. Identical across 繁體 / 新字体 / 简体.
Note that CJK languages have a separate, more anatomical word for "head" — 頭 (Mandarin tóu, Japanese atama). 首 is reserved for the body part in formal/medical use, but dominates the metaphorical "leadership / first" sense in compounds.
Mandarin: shǒu, dipping 3rd tone. 首都 (shǒudū, capital — "head capital"), 首相 (shǒuxiàng, prime minister — "head minister"), 首先 (shǒuxiān, first of all), 首要 (shǒuyào, primary), 元首 (yuánshǒu, head of state). Also a measure word for poems: 一首诗 (yī shǒu shī, one poem) — quirky but rooted in the "head/first item" metaphor.
Japanese: on-reading シュ (shu) in 首相 (shushō, prime minister), 首都 (shuto, capital), 首脳 (shunō, leader). The kun-reading くび (kubi) is the everyday word for neck (not head!), with extended meaning "to fire/dismiss" — 首になる (kubi ni naru, "to be fired", literally "to become a neck"). Watch the meaning shift: 首 means head/leader in Sino-Japanese compounds but neck in native Japanese usage.
The derived character 道 (path/way — 首 + 辶) literally means "the head walking" — pointing the way forward.
Memory aid: hair (the three top strokes) above a face (the box below). The leader of the body.
- 首都しゅとcapital
- 首相しゅしょうprime minister
- 首都shǒudūcapital
- 首先shǒuxiānfirstly
口kǒu · コウ · クmouth
口 is a simple square — an open mouth viewed from the front, drawn in three strokes. Identical across 繁體 / 新字体 / 简体.
It is one of the most productive radicals in the entire script, generating two whole categories of compound. First, mouth-actions: 吃 (eat), 喝 (drink), 吐 (spit/vomit), 呼 (call/breathe out), 吸 (inhale), 唱 (sing), 叫 (shout), 呢 (a final particle), 吗 (a question particle). Second, "opening / passage" by metaphor: 名 (name — a mouth giving a label), 句 (sentence — what a mouth produces), 員 (member — a "mouth" inside a frame), 古 (ancient — ten generations of mouths), 周 (around).
The metaphor extends beyond the body: anywhere people or things flow in and out, Chinese imagines a "mouth". 入口 (entrance), 出口 (exit), 港口 (harbor), 人口 (population — "human mouths"), 窗口 (window/counter). When you see 口 in city signage at airports, train stations, and shopping malls, it is always marking an entrance or exit.
Mandarin: kǒu, dipping 3rd tone. Also a measure word for people in a household: 三口人 (sān kǒu rén, "three people in the family"), 四口之家 (sì kǒu zhī jiā, "a family of four mouths"). The mouth-as-headcount metaphor is built into the grammar.
Japanese: on-reading コウ (kō) in 人口 (jinkō, population), 入口 (iriguchi or nyūkō); ク (ku) in 口調 (kuchō, tone of voice). The kun-reading くち (kuchi) is the everyday word — 口 (kuchi, mouth), 入り口 (iriguchi, entrance — a kun-reading mix). 一口 (hitokuchi, "one mouthful").
Memory aid: a small square. Open mouth. The picture is the meaning.
- 入口いりぐちentrance
- 人口じんこうpopulation
- 人口rénkǒupopulation
- 出口chūkǒuexit; export
鼻bí · ビnose
鼻 has one of the most charming etymologies in the script. The original character for "nose" was 自 — a stylized front-view picture of a nose. Speakers would touch their own nose to indicate "me, myself", and over centuries 自 drifted to mean "self / from / by oneself" exclusively. Left without a "nose" word, scribes built a new one: they kept 自 (the original nose-picture) on top, then added 田 (field — actually a phonetic indicator) and 廾 (a base/stand), producing 鼻. The new character preserves the old picture inside itself like a fossil.
Identical across 繁體 / 新字体 / 简体.
Mandarin: bí, rising 2nd tone. 鼻子 (bízi) is the everyday word for nose. 鼻孔 (bíkǒng, nostril — "nose hole"), 鼻血 (bíxuè, nosebleed). The verb 流鼻涕 (liú bítì, "to have a runny nose") is a kid-vocab classic.
Japanese: on-reading ビ (bi) appears in 耳鼻科 (jibika, ENT clinic) and 鼻音 (bion, nasal sound — phonetics). The kun-reading はな (hana) is the everyday word — 鼻 (hana, nose). Watch for the homophone trap: 花 (hana, flower) is identical in spoken Japanese, distinguished only by context and pitch accent. Also 鼻血 (hanaji, nosebleed) — note the rendaku voicing.
The expression 鼻が高い (hana ga takai, "the nose is tall") means proud — the same metaphor English uses with "stuck-up" but with a positive spin in Japanese.
Memory aid: 自 (original nose picture) on top, 廾 (a base) on the bottom — a nose mounted on a small pedestal. The character protects its own etymology.
