转 turn + 折 bend = events bend onto a new course
转 means turn/rotate and 折 means bend/snap; together they mark the spot where a story or situation bends sharply, the turning point or plot shift.
转 — car radical 车 + 专 (phonetic)
转 is a semantic-phonetic compound. The left side 车 (cart/wheel) gives the meaning, evoking something that turns or rotates like a wheel. The right side 专 supplies the sound. Originally referring to the turning of a cart's wheels, it broadened to mean 'turn,' 'rotate,' or 'shift' in general.
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).
