Chinese Compound Words
Six Structural Types (复合词)

Most Chinese vocabulary is built through compounding — combining two morphemes to create a new word. The six structural types below cover the vast majority of compound words you will encounter. Master these patterns and vocabulary acquisition becomes systematic.

1Coordinative Compounds (联合式 liánhé shì)

Both components contribute equally to the meaning. They may be near-synonyms, antonyms, or complementary concepts that together define a broader idea. Neither part dominates — the compound's meaning is the sum or blend of both.

ChinesePinyinEnglishNotes
朋友péngyǒufriend朋 (companion) + 友 (friend) — near synonyms
语言yǔyánlanguage语 (speech) + 言 (words) — near synonyms
买卖mǎimàitrade / business买 (buy) + 卖 (sell) — opposites forming a whole
来往láiwǎngcontact / dealings来 (come) + 往 (go) — opposites forming a concept
道路dàolùroad / path道 (way) + 路 (road) — near synonyms
父母fùmǔparents父 (father) + 母 (mother) — complementary pair

2Modifier-Head Compounds (偏正式 piānzhèng shì)

The first morpheme modifies, qualifies, or narrows the second. The head (second morpheme) determines the word's category; the modifier specifies what kind. This mirrors the standard Chinese adjective-noun order in phrases.

ChinesePinyinEnglishNotes
汉字hànzìChinese character汉 (Han) modifies 字 (character)
电话diànhuàtelephone电 (electric) modifies 话 (speech)
书店shūdiànbookshop书 (book) modifies 店 (shop)
飞机场fēijīchǎngairport飞机 (airplane) modifies 场 (field/place)
冷水lěngshuǐcold water冷 (cold) modifies 水 (water)
大学dàxuéuniversity大 (big/great) modifies 学 (learning)
Decoding strategy: For modifier-head compounds, ask "what kind of [head] is it?" — 书店 = what kind of shop? A book shop. 汽车 = what kind of vehicle? A steam/gas vehicle = car. This pattern generates a large proportion of Chinese nouns.

3Verb-Object Compounds (动宾式 dòngbīn shì)

The first morpheme is a verb; the second is its object. The compound as a whole functions as a verb. These are common in everyday speech — many routine activities are expressed through verb-object compounds. Note that the internal object is usually not replaceable: you say 吃饭 (eat a meal) as a unit, even when specifying a different food.

ChinesePinyinEnglishNotes
吃饭chīfàneat a meal吃 (eat) + 饭 (rice/meal)
开心kāixīnhappy / joyful开 (open) + 心 (heart) — metaphorical
留学liúxuéstudy abroad留 (stay/remain) + 学 (study)
睡觉shuìjiàosleep睡 (sleep) + 觉 (sleep/sense)
说话shuōhuàspeak / talk说 (say) + 话 (speech)
跑步pǎobùrun / jog跑 (run) + 步 (step)

4Subject-Predicate Compounds (主谓式 zhǔwèi shì)

The first morpheme acts as the subject of the action or state expressed by the second morpheme. These compounds are often derived from mini-sentences. The internal logic is vivid and memorable — 地震 is literally "the earth shakes", and 年轻 is "years are light."

ChinesePinyinEnglishNotes
地震dìzhènearthquake地 (earth) + 震 (shake) — earth shakes
年轻niánqīngyoung年 (year) + 轻 (light) — years are light
心疼xīnténgfeel sorry for; dote on心 (heart) + 疼 (ache) — heart aches
眼红yǎnhóngenvious / jealous眼 (eye) + 红 (red) — eyes turn red
胆小dǎnxiǎotimid / cowardly胆 (gall/courage) + 小 (small) — small courage

5Verb-Complement Compounds (动补式 dòngbǔ shì)

The first morpheme is a verb; the second is its result or direction — a complement that tells you the outcome of the action. These are directly related to the resultative and directional complement grammar patterns. Understanding them helps both vocabulary and sentence structure.

ChinesePinyinEnglishNotes
说明shuōmíngexplain说 (say) + 明 (clear) — resultative complement
提高tígāoimprove / raise提 (raise/lift) + 高 (high) — resultative complement
写完xiěwánfinish writing写 (write) + 完 (finish) — resultative complement
走进zǒujìnwalk into走 (walk) + 进 (enter) — directional complement
看懂kàndǒngunderstand by reading看 (read/look) + 懂 (understand) — resultative
做好zuòhǎodo well / complete properly做 (do) + 好 (good/well) — resultative
Verb-complement compounds and grammar: The same logic appears at the sentence level. 写得完 (can finish writing) and 写不完 (cannot finish writing) use the same base compound 写完 with 得 (achievable) or 不 (not achievable) inserted in the middle. The compound and the potential form share structure.

6Reduplication (重叠式 chóngdié shì)

Reduplication repeats a morpheme or word to add nuance. For monosyllabic verbs, AA reduplication softens the action or indicates doing something briefly. For adjectives, AA reduplication often intensifies or adds descriptive richness. The AABB pattern reduplicate two-morpheme compounds and often appears in formal or literary contexts.

ChinesePinyinEnglishNotes
慢慢mànmànslowly慢 (slow) → 慢慢 — adverb, gentler tone
看看kànkàntake a look看 (look) → 看看 — brief or casual action
走走zǒuzǒutake a stroll走 (walk) → 走走 — light/casual doing
高高兴兴gāogāoxìngxìnghappilyAABB pattern: 高兴 (happy) reduplicated fully
清清楚楚qīngqīngchǔchǔclearly / distinctlyAABB: 清楚 (clear) reduplicated
一天天yītiāntiānday by day一 + NN pattern indicating gradual change
