招呼
zhāohū · HSK 4
to call out to; to greet
👋 招 = beckon + 呼 = call out; together = hail someone, say hi
招 (zhāo) means to beckon or summon with a hand gesture; 呼 (hū) means to call out or shout. Combined, 招呼 covers greeting, hailing, and notifying — the act of getting someone's attention to acknowledge them.
招 — hand radical 扌 + 召 (call)
招 is a semantic-phonetic compound. The hand radical 扌 supplies the meaning—an action done with the hand—while 召 (to summon, call) gives both phonetic value and reinforces the sense. Together they depict beckoning someone with a hand gesture, extended to 'recruit' or 'attract'.
