On the earth

Phonetic-semantic compound: 土 (earth, the previously discussed altar/soil character) + 也 (a phonetic component). Where 土 means physical dirt and 大地 means abstract earth-as-place, 地 alone covers the location/ground/region sense — a more abstract sibling of 土. Identical across 繁體 / 新字体 / 简体.

Mandarin has TWO crucial readings for 地: — dì (4th tone): ground / earth / region / place. 地球 (dìqiú, Earth — the planet), 地图 (dìtú, map), 地方 (dìfang, place — neutral final tone, very high frequency), 地铁 (dìtiě, subway — "earth iron"), 地址 (dìzhǐ, address), 土地 (tǔdì, land). — de (neutral tone): a grammatical particle that turns adjectives into adverbs. 慢慢地走 (mànmàn de zǒu, "walk slowly"), 高兴地说 (gāoxìng de shuō, "happily said"). This pattern — adjective + 地 + verb — is one of the foundational Mandarin grammar structures. Learners must distinguish dì (the noun) from de (the particle); the same character does double duty.

Japanese: TWO on-readings. チ (chi) is dominant — 地球 (chikyū, Earth/planet), 地理 (chiri, geography), 地方 (chihō, region), 地下 (chika, underground). ジ (ji) appears in 地面 (jimen, ground / surface), 地震 (jishin, earthquake — every Japanese resident's essential vocabulary), 地味 (jimi, plain / understated — culturally important Japanese aesthetic adjective). Kun-readings are essentially absent — 地 is exclusively on-reading in Japanese practice.

The Japanese cultural keyword 地震 (jishin, earthquake) — given Japan's position on the Pacific Ring of Fire — is among the first essential vocabulary for visitors. Every Japanese building displays 地震対策 (earthquake preparedness) signs.

Memory aid: earth-soil (土) + phonetic — the abstract "ground" beneath everything.

Phonetic-semantic compound: 里 (village / 1 li distance unit) + 予 (a phonetic). The encoded meaning: "what extends beyond the village" → wild fields / open countryside. From this physical image grew abstract senses: "untamed / wild / range / domain". The civilization-vs-wildness opposition is encoded directly. Identical across 繁體 / 新字体 / 简体.

Mandarin: yě, dipping 3rd tone. 野生 (yěshēng, wild — 野生动物 wild animals), 野心 (yěxīn, ambition — "wild heart", carries slightly negative connotation), 野餐 (yěcān, picnic — "wild meal"), 田野 (tiányě, fields), 视野 (shìyě, field of vision), 越野 (yuèyě, off-road / cross-country).

Japanese: on-reading ヤ (ya) — 野球 (yakyū, baseball — Japan's national sport, "field-ball"), 野菜 (yasai, vegetables — "field plants", THE everyday word for vegetables), 分野 (bun'ya, field of expertise / domain), 野心 (yashin, ambition), 平野 (heiya, plains), 視野 (shiya, field of vision). Kun-reading の (no) appears in geographical place names and poetry — 野原 (nohara, meadow), 上野 (Ueno, Tokyo neighborhood), 武蔵野 (Musashino, Tokyo region — "Musashi plains").

野球 (yakyū, baseball) — Japan's national sport — was named in 1895 by Chūman Kanae, who calqued "baseball" using 野 (field) + 球 (ball). The name has stuck as a Japanese-coined word that even Chinese eventually borrowed back as 野球. So 野球 is a Japanese loanword in modern Chinese.

野菜 (yasai, vegetables) is among the foundational food vocabulary every Japanese learner masters in the first weeks.

Memory aid: village + open extension = the open country beyond civilization.

原 shows a spring (泉) welling up beneath a cliff (厂) — its original sense is "the source of a spring." From there grew "origin, source, the original," and the broad plain where the spring flows out split off the sense "field, plain." To make the "source" meaning clearer, 源 (source) was later formed by adding water 水.

Mandarin: yuán, 2nd tone. 原来 (yuánlái, as it turns out / originally), 原因 (yuányīn, cause), 原谅 (yuánliàng, to forgive), 草原 (cǎoyuán, grassland), 高原 (gāoyuán, plateau).

Japanese: on-reading ゲン (gen), kun はら (hara). 原 (hara, plain), 原因 (gen'in, cause), 高原 (kōgen, plateau), 野原 (nohara, field), 秋葉原 (Akihabara). はら is common in Japanese place names and surnames — 原田 (Harada), 藤原 (Fujiwara).

Korean hanja-sound "won": 原因 (wonin, cause), 原理 (wolli, principle), 原來 (wollae, originally), 草原 (chowon, grassland), 平原 (pyeongwon, plain). Both senses — "source" and "plain" — live on.

Memory aid: a spring (泉) welling beneath a cliff (厂) — the source where water begins, and the plain that water waters.

岩 is a compound ideograph stacking 山 (mountain) over 石 (stone) — the stone that makes up a mountain, that is, a boulder or crag. With 山 and 石 plainly visible, its meaning is transparent. An older form 嵒 (three stones atop a mountain) also existed, but the simpler 岩 became standard.

Korean hanja-sound "am": 岩石 (amseok, rock), 火成岩 (hwaseongam, igneous rock), 堆積岩 (toejeogam, sedimentary rock), 變成岩 (byeonseongam, metamorphic rock), 鎔岩 (yongam, lava). The whole geological classification of rock uses this character.

Mandarin: yán, 2nd tone. 岩石 (yánshí, rock), 岩浆 (yánjiāng, magma), 熔岩 (róngyán, lava).

Japanese: on-reading ガン (gan), kun いわ (iwa). 岩 (iwa, boulder), 岩石 (ganseki, rock), 溶岩 (yōgan, lava), 岩場 (iwaba, rocky ground). It is common in surnames — 岩田 (Iwata), 岩崎 (Iwasaki, founders of Mitsubishi).

Memory aid: stone (石) beneath a mountain (山) — the great stone that makes up a mountain, a boulder.

土 pictures a small mound of earth heaped on the ground line. The earliest oracle bone forms suggest a sacrificial earth altar — a small pile of soil set apart for ritual. Identical across 繁體 / 新字体 / 简体.

土 sits at the center of the East Asian Five Phases system (五行: wood, fire, earth, metal, water) — every other element gets a planet and a weekday in the seven-day cycle. Saturday is "earth day" (Saturn, the earth planet).

As a radical, 土 marks any character involving soil, ground, or built things made from earth: 地 (ground), 場 (place — originally a flat earthen area), 城 (city wall, built of pounded earth), 坊 (block/quarter), 塊 (lump), 塗 (smear/paint). When you see 土 on the left of a character, expect dirt, terrain, or a structure rooted in the ground.

Mandarin: tǔ, dipping 3rd tone. 土地 (tǔdì, land), 国土 (guótǔ, national territory), 土豆 (tǔdòu, potato — literally "earth bean"), 本土 (běntǔ, native/local). The adjective 土 colloquially means "rustic/old-fashioned" — calling someone's outfit 很土 means "very country bumpkin".

Japanese: on-readings ド (do) in 土地 (tochi, land — note irregular reading) and 土曜日 (doyōbi, Saturday); ト (to) in 土地 (tochi, again) and 国土 (kokudo). The kun-reading つち (tsuchi) is the everyday word for "soil" or "dirt".

Memory aid: a horizontal ground line with a small vertical mound + a top stroke — earth piled up. The character literally sits on its own ground.

田 shows a field viewed from above — a frame divided by a cross into four square plots. The internal cross represents the irrigation paths or footpaths between paddies. Identical across 繁體 / 新字体 / 简体.

The character is one of the most productive components in the entire script. As a radical it builds farming and field-shape vocabulary: 男 (man — historically "field-power", the laborer), 界 (boundary — what divides fields), 留 (stay — to remain in one's field), 番 (turn/number — taking turns at the field), 略 (strategy — survey of fields), 畑 (Japan-only kokuji: a dry field, contrasting with 田 wet rice paddy).

Mandarin: tián, rising 2nd tone. 田地 (tiándì, farmland), 田野 (tiányě, fields/countryside), 油田 (yóutián, oil field), 水田 (shuǐtián, paddy field). Also a major surname — particularly notable in Japan and China.

Japanese is where 田 lights up. The on-reading デン (den) appears in 田園 (denen, rural area). The kun-reading た (ta) is one of the densest surname-building components in Japanese: 田中 (Tanaka, "in the field" — extremely common), 山田 (Yamada, "mountain field"), 本田 (Honda, "true field" — yes, the car brand), 豊田 (Toyota, "abundant field" — yes, the other car brand), 吉田 (Yoshida, "lucky field"), 田村 (Tamura, "field village"). Reading Japanese surnames almost requires you to recognize 田 reflexively.

Memory aid: a square box with a plus-sign inside — a rice paddy seen from a hot-air balloon.

山 is the most transparent pictograph in the entire script: three peaks side by side, the middle one tallest. Oracle bone inscriptions show essentially the same silhouette you would sketch today if asked to draw "mountain range" without instruction. Identical across 繁體 / 新字体 / 简体 — three strokes, no reform needed in three thousand years.

Mandarin: shān, level 1st tone. 山 alone is mountain; 山水 (shānshuǐ, "mountains and waters") is the entire genre of classical landscape painting. Place names lean on it heavily: 泰山 (Tài Shān, sacred Mount Tai), 黄山 (Huáng Shān, Yellow Mountain), 山东 (Shāndōng, "east of the mountain") — a province named for its position relative to a single peak.

Japanese: on-reading サン (san) shows up in 火山 (kazan, volcano), 登山 (tozan, mountaineering), and most famously 富士山 (Fujisan). The kun-reading やま (yama) is everyday — and one of the commonest surnames in Japan: 山田 (Yamada), 山本 (Yamamoto), 山口 (Yamaguchi). Japanese folk religion still treats individual mountains as gods.

As a radical, 山 marks geography: 岩 (rock), 峰 (peak), 岡 (hill), 島 (island — sea + mountain). When you see ⼭ at the top or left of a character, the meaning will almost always involve elevation or terrain.

Memory aid: three peaks, middle tallest. Draw what you see.

石 pictures a stone fallen at the foot of a cliff. The 厂 element on top is a cliff face seen from the side; the 口 below is the loose rock that broke off and rolled down. Identical across 繁體 / 新字体 / 简体.

As a radical, 石 marks anything stony, mineral, or hard: 砂 (sand), 砲 (cannon — stone-projectile weapon), 碑 (stele/stone tablet), 礎 (foundation stone), 確 (firm/certain — originally "as solid as stone"), 磁 (magnetic), 砂糖 (sugar — note the stone radical for crystalline substance). When 石 appears on the left, the meaning is almost guaranteed to involve rock, mineral, or hardness.

Mandarin: shí, rising 2nd tone. 石头 (shítou, stone/rock), 石油 (shíyóu, petroleum — "stone oil"), 化石 (huàshí, fossil — "transformed stone"), 钻石 (zuànshí, diamond), 宝石 (bǎoshí, gemstone). The character also serves as a common surname.

Japanese: on-reading セキ (seki) in 化石 (kaseki, fossil), 宝石 (hōseki, jewel), 石碑 (sekihi, stone monument). Less common on-reading シャク (shaku) survives in older readings. The kun-reading いし (ishi) is the everyday word — 石 (ishi, stone), 石橋 (ishibashi, stone bridge — also a common surname). Plus 小石 (koishi, pebble) and 石垣 (ishigaki, stone wall) — Okinawan castle architecture is famous for it.

Memory aid: a cliff overhang (the curved 厂 stroke) with a fallen rock (the 口 box) tucked underneath. Erosion in two strokes.
