门当户对
mén dāng hù duì · HSK 7
the families are well-matched in terms of social status
🚪🚪 门当户对 = door + match + household + pair: two families whose doorways are equals
Old marriage idiom from sizing up the front gates: 门 door and 户 household both mean the home, while 当 match and 对 pair say the two sides line up. A well-matched union of equal social standing.
门 — pictograph of double-leaf gate
门 is a pictograph showing a pair of swinging doors hung in a doorway, originally drawn as 門 in oracle-bone script with two clear leaves. The simplified form 门 keeps the same outline with fewer strokes. It still means 'gate' or 'door' and serves as a phonetic in characters like 们, 问, and 闷.
当 — small ⺌ + crown 冖 + hand 彐 (simplified from 當: 尚 + 田)
Originally written 當, combining 田 'field' with 尚 as a phonetic. The early sense was 'to match' or 'face' a field of equal value, extended to 'correspond to', 'ought to', and 'serve as'. The simplified form 当 streamlines the upper 尚 component.
户 — single-leaf door (half of 門)
户 is a pictograph showing a single-leaf door, originally drawn as half of 門 (a double door). It came to mean 'door,' then by extension 'household' or 'family,' since a door marks one dwelling. Today it commonly means 'household' or 'account.'
对 — 又 (hand) + 寸 (measure/rule)
Originally depicted a hand (又) holding or responding to something, with 寸 added as a phonetic-semantic element suggesting measured action. The traditional form 對 showed a hand presenting an object in reply, giving the core sense of 'to answer' or 'face toward.' Modern meanings like 'correct' and 'pair' grew from this idea of matching response.
