👋 扌 hand + 军 army: a hand commanding an army — to wave, brandish, conduct
挥 — hand radical 扌 + 军 jūn (phonetic)
A semantic-phonetic compound: the hand radical 扌 indicates an action done with the hand, while 军 supplies the sound (jūn → huī). The original sense was to wave, brandish, or swing the hand, later extended to 'wield,' 'command,' and figurative uses like 'disperse' or 'wipe away.'
