为主

give first place to
👑 为 (act as) + 主 (master) = take as the main thing
为 means to act as or serve as; 主 means master, host, or main one. Together 为主 literally reads as taking something as the master or principal element, hence giving it first place or priority.
为 — simplified form of 為; from 爪 (claw/hand) over 象 (elephant)
The traditional form 為 originally depicted a hand leading an elephant, suggesting the act of doing or making work. Over time it generalized to mean 'to do, to act, for the sake of.' The simplified 为 preserves this 'do/for' meaning, with pronunciation shifting between wéi ('to be, to do') and wèi ('for, because of').
主 — flame/lamp on top of a stand 王
Originally a pictograph of a lamp with a flame on top of its stand, representing the lord or master of the household who tended the fire. The meaning extended from 'lamp/host' to 'master, owner, main, principal'. The character 炷 (wick) preserves the original 'lamp' sense.
