断 is written with 11 strokes. The animation replays automatically.
断 (duàn) is a verb meaning 'to break,' 'to snap,' or 'to cut off / sever,' used when something long or continuous is severed into pieces — a rope, a bone, a wire, or a connection.
It also extends to interrupting continuity: 断电 (power cut), 断网 (lose internet), 中断 (to interrupt). A second sense is 'to judge / decide' (判断 to judge, 诊断 to diagnose). It is neutral in register.
Two differences from English: 断 focuses on the severing of something continuous, so a snapped rope is 绳子断了 (the rope broke, intransitive, thing as subject), while a shattered cup uses 碎 (suì) or 破 (pò) instead; and as an adverb in the pattern 断不 / 断然 it means 'absolutely (not),' a formal emphatic. Use 断 for long things that snap or connections that get cut, not for things that shatter.

折 (zhé) means to snap or fold something by bending (折断 snap in two, 折纸 fold paper). 断 is the state of being severed. Often combined: 折断 = to break by bending. 断 alone covers snapping and cutting off connections too.
