fold, break, fracture, bend, yield, submit
折 centers on applying force to change shape or direction: physically folding, bending, or breaking something, and metaphorically yielding or submitting to pressure.
折 combines 扌 (hand) and 斤 (axe), suggesting a hand using an axe to cut or break something. The meanings of folding, bending, and breaking likely derive from this action.
A hand 扌 holding an axe 斤 can fold or break things by applying force. Imagine bending a branch until it snaps, or folding paper with a sharp crease.
For セツ, imagine folding a set of papers neatly: set -> セツ, and your hand with an axe-like creaser makes the fold.
