便利
べんり · benri · JLPT N5 · na-adj
convenient
🏪 便利 = convenient + benefit; a konbini is a benri store
便 means convenient or easy, 利 means benefit or advantage: an easy advantage is handy. The Japanese convenience store, konbini, is formally a 便利店-style idea: the shop named for being benri.
便 — person 亻 + change 更
A semantic compound: 亻(person) beside 更 (to change/replace). The original sense was a person making things easier or more convenient by adjusting them. From 'convenient' it extended to 'then/thereupon' (biàn) and to bodily 'discharge' (as in 大便).
利 — grain 禾 + knife 刂
Originally a pictograph showing a knife (刂) cutting grain (禾), depicting harvest. From the idea of a sharp blade reaping crops, it extended to mean 'sharp,' then 'benefit,' 'profit,' or 'advantage' — the gain that comes from a successful harvest.
