お出掛け
おでかけ · odekake · JLPT N2 · noun
excursion
🧺 出 (de) = exit + 掛け (kake) = set off, with polite お in front: an exit-and-set-off trip = outing
お is a polite prefix. 出掛ける (dekakeru) means to leave home on a trip or errand. Break it into de (exit) and kake (set off), so leaving the house to go somewhere is the outing.
出 — foot 止 emerging from enclosure 凵
出 is a pictograph showing a foot or plant stepping out of a hollow or enclosure, depicting the act of going forth. The original sense of 'coming out' or 'emerging' has remained stable since oracle bone script. It now broadly means 'to exit, go out, or produce.'
