下坠
xiàzhuì · HSK 7
Fall
⬇️ 下坠 = 下 (down) + 坠 (drop) — to fall downward
下 means down/below and 坠 means to drop or sink. Together 下坠 is the downward fall, the motion of dropping from a height.
下 — horizontal line 一 + mark below
下 is an indicative character: a long horizontal line represents a reference level, and a shorter stroke placed beneath it points to the area below. The original meaning 'below, down' comes directly from this spatial diagram, and it later extended to verbs like 'descend' and 'lower'.
坠 — earth 土 + 队 (phonetic, originally 阜 mound)
A semantic-phonetic compound: 土 'earth' gives the meaning of falling to the ground, while the right side (historically 阜, a mound or cliff) supplied the sound and reinforced the idea of dropping from a height. The original sense 'to fall down' has remained stable into modern Chinese.
