The kanji 墜 signifies "to fall," "to collapse," or "to descend." It implies a downward movement, often with a sense of suddenness or a loss of support. This can apply to physical objects, but it can also be used metaphorically to describe a decline or a fall from a higher state.

The kanji 墜 is a 形声文字 (keisei moji), a phono-semantic compound character. It is composed of two parts: 　 •The radical 坴 (fū), on the right side of the character. This component provides the semantic element of "earth" or "ground." •The phonetic component 隊 (tai), on the left side, which gives the sound "tsui." The meaning connection here is that something coming down will eventually meet the ground.
