Semantic Clue (形旁): 页 (Originally related to the head or face features.)

5. History

Liushu category: Phono-semantic (形声)

Origin: Originally written as 鬚, depicting facial hair on a head. Over time, the character was simplified to 须 for general auxiliary and modal uses like 'must' or 'to have to'.

Semantic Evolution: From the physical meaning of 'beard/facial hair' (now mostly written as 鬚), it shifted through semantic borrowing to mean 'wait' and further into the modal auxiliary meaning of 'must' or 'ought to'.

In classical Chinese, 须 frequently appeared as a noun meaning beard or whiskers before taking on grammatical functions.
