4. Components
Radical石 · Stone Radical (rock, stone, solid mineral)
Semantic Clue (形旁):石 (Indicates that the breaking involves hard objects like stone or things that shatter easily like hard materials.)
Origin: Combined from 石 (stone) representing hard material and 卒 (to finish/end) suggesting the complete destruction or breaking down of that material.
Semantic Evolution: Originally referred to crushing stone into bits, later generalized to any object shattering or breaking into fragments.
The component 卒 also contributes a phonetic element related to the ancient pronunciation ending in entering tones.
