5. History
Liushu category: Phono-semantic (形声)
Origin: Originally combined 广 (cliff/shelter) with 氐 (base/root) to signify the bottom or foundation of a building under a cliff.
Semantic Evolution: From meaning 'bottom' or 'foundation', it was borrowed phonetically to serve as a possessive particle (synonymous with 的), and also appears in words like 月底 (end of the month) and 彻底 (thorough).
In classical Chinese literature, 底 was frequently used interchangeably with 的 as a genitive marker.
