柜子
guì zi · HSK 5
cupboard
🗄️ 柜 = cupboard + 子 (noun suffix); 柜 has 木 (wood) radical
柜 combines 木 (wood) with 巨 (giant/huge), hinting at a large wooden storage piece. 子 is a common noun suffix with no separate meaning here. So 柜子 literally reads as wood-giant-thing — a wooden cabinet.
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.
