💍 ご主人 = honorific go + 主 master + 人 person: the master of the house
主人 (shujin) literally means master-person, the head of a household. Adding the polite prefix ご makes it respectful, so it is used for someone else's husband, never your own. For your own husband, say 主人 or 夫 (otto).
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.
人 — pictograph of a standing person
人 is a pictograph showing a person viewed from the side, with two strokes representing the legs and torso of a standing human. In oracle bone script it clearly depicted a figure leaning slightly forward. The meaning has remained 'person' or 'human' throughout its history.
