出発
しゅっぱつする · shuppatsusuru · JLPT N4 · noun
departure
🚆 出発 = go out (出) + set off (発): shuppatsu, the moment you leave
出 means to exit and 発 means to launch or start off, so together they name the act of setting out. Sound hook: shuppatsu has a sharp double p, like the pop of a starting signal. Add する to make the verb to depart.
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.'
