verb — to wave, brandish, wield; to command, direct
字源 FORM — what the parts do
扌義the hand that swings
IFTjūn → huī — the j wears to h, the rime and tone shift with it
The hand (扌) swings; 軍 jūn carries the sound, worn far to huī. 說文 reads it 奮也 — to rouse, to throw the arm out. From the swinging arm: to wave (揮手), to wield a brush (揮毫), to direct troops (指揮). It rides the 軍 series: 輝、運.
故事 STORY — a scene to remember it by
手（扌）一揚，像號令大軍（軍）那樣往前一指。
