to turn up
👖 折る (oru, fold) + 返す (kaesu, return) = fold back, like a trouser cuff turned up
Compound of 折る (to fold) and 返す (to return or send back). Used for folding a hem or sleeve back on itself, and for a road or path that doubles back.
折 — hand 扌 + axe 斤
Originally written as 折 with a hand (扌) breaking or chopping something with an axe (斤), depicting the act of snapping or cutting in two. The core meaning 'to break, snap, fold' extends metaphorically to 'bend,' 'turn back,' and 'discount' (as in reducing a price by breaking off part).
