Liushu category: Indicative (指事)
Origin: In Oracle Bone script, it was written as the character '大' (a person) with two dots added pointing to the armpits to indicate 'armpit' or 'side'.
Semantic Evolution: The meaning shifted via borrowing (假借) from the physical body part 'armpits' to the grammatical particle 'also' or 'too'.
It is one of the classic examples of a character whose ancient concrete meaning has been completely replaced by its phonetic loan meaning in modern Chinese.
