🧍 主 (master/main) + 体 (body) = main body
主 means host or main; 体 means body or form. Together they name the principal entity or subject — the main body of a text, an organization, or a philosophical subject.
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.
