出入り
でいり · deiri · JLPT N2 · noun
out
🚪 出 (out) + 入り (entry): the movement going out and coming in, in both directions
出 means exit and 入 means enter, so 出入り covers movement in both directions. 出入りが多い describes a place with heavy foot traffic, such as a busy shop or office.
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.'
入 — single pictograph, two slanting strokes
入 is a pictograph showing an arrowhead or pointed entrance, with two strokes converging downward to suggest something going inward. The original sense was 'to enter,' and it still carries that meaning today. It contrasts visually with 人 (person), where the strokes cross differently at the top.
