两口子
liǎng koǔ zi · HSK 7
husband and wife
👫 两 two + 口 mouths + 子 suffix = the two mouths under one roof, a married couple
两口子 counts a household by its mouths: 两 (two) plus 口 (mouth) plus the noun-ending 子. Two mouths sharing one home is the everyday word for husband and wife.
两 — two halves under 一, mirrored 入 components inside 冂
两 originally depicted a balance scale or a pair of matched objects, symbolizing duality and equality. The two inner components represent the two equal sides being weighed or paired. Over time it came to mean 'two' (especially for paired things) and also a traditional unit of weight (tael).
口 — pictograph of an open mouth
口 is one of the oldest pictographs in Chinese, originally drawn as a simple outline of an open mouth. Its core meaning 'mouth' extended naturally to 'opening' or 'entrance', as in 入口 (entrance). It also serves as a common radical in characters related to speech, eating, or apertures.
子 — pictograph of a baby/child with arms out
子 began as a pictograph of a swaddled infant with a large head and outstretched arms, originally meaning 'baby' or 'child.' From there it broadened to 'son,' 'offspring,' and a respectful suffix for masters like 孔子 (Confucius). It also became one of the twelve earthly branches.
