芒
芒 ＝ 艸 ＋ 亡
ㄇㄤˊ · máng
noun — the awn of grass/grain; a sharp point, a ray
字源 FORM — what the parts do
艸義grass — the plant on top (寫作 艹)
{m,w}Iwáng → máng — the w- crossing into m-
Grass (艹) on top; 亡 wáng underneath gives the sound, the w- crossing to m-. The sharp bristle on a stalk of grain is the awn — from it, any fine sharp point: 鋒芒. The same 亡 builds 忙、茫、盲. The mango 芒果 borrows only the sound.
