Tips

usage
Default reading mó covers all the verb senses: physical grinding (磨刀 sharpen a blade), figurative wearing-down (磨练 temper, 折磨 torment), and the colloquial 'dawdle / pester' sense (磨蹭). Distinguished from its homophone 摩 (hand-radical, 'rub') by the stone radical: 磨 is grinding ON a stone.
culture
铁杵磨成针 - 'grind an iron pestle into a needle.' A famous idiom about perseverance, attributed to a story about the young 李白: as a boy, he met an old woman patiently grinding an iron rod down to a sewing needle, and the lesson convinced him to study seriously.

Components

radical
石 shí
stone
Bottom 石 - the indexing radical (Kangxi #112). Grinding requires stone: millstones, whetstones, mortars. The stone radical specifies that this 'wearing-down' action is abrasion against rock, distinguishing 磨 from its homophone 摩 (rub with hand, hand radical). Same 石 family: 砖 (brick), 碎 (shatter), 硬 (hard).
phonetic
麻 má
hemp
Top-outer 麻 supplies the sound - má → mó with only a vowel shift. 麻 itself shows 广 (shelter) over hemp fibres being processed; the fibres were beaten and rubbed against stone or wood to soften them, faintly evoking the grinding action. Same má/mó phonetic family: 蘑 (mushroom), 摩 (rub), 魔 (demon).
