Several parts combine into one character.

招 is a phonetic-semantic compound: 扌 (the hand radical) + 召 (zhào, "to summon by voice" — itself depicting a mouth calling someone forward). 召 already meant "to call vocally"; 招 adds the hand radical to mark "calling with a beckoning gesture." The pair 召 / 招 work together: 召 is the verbal summons, 招 is the gesture of beckoning. Together they cover the full vocabulary of inviting and calling someone over.

Korean reading "cho." 招待 (chodae, invitation), 招請 (chocheong, formal invitation — used in diplomatic and formal academic contexts), 招聘 (chobing, formal recruitment / appointing — used when bringing in a senior expert: "professor recruitment"), 招集 (choju p, summoning / convocation — military and political contexts), 招來 (chorae, "to bring upon / invite a result" — used metaphorically: "to bring disaster upon oneself").

Mandarin zhāo, 1st tone. 招 (zhāo, to beckon / recruit / attract), 招呼 (zhāohu, "to call out a greeting" = to greet / call someone's attention — basic spoken vocabulary: 打招呼 dǎ zhāohu = "to greet"), 招待 (zhāodài, to entertain / receive guests), 招聘 (zhāopìn, to recruit / hire — appears constantly in Chinese job postings), 招手 (zhāoshǒu, to wave hand / hail), 招牌 (zhāopái, signboard / brand — what attracts customers).

Japanese on-reading ショウ (shō) — 招待 (shōtai, invitation), 招集 (shōshū, convocation), 招請 (shōsei, formal invitation). Kun-reading まねく (maneku) — 招く (maneku, "to invite / beckon / summon / bring about"). Japanese extends the meaning into causation: 災いを招く (wazawai o maneku, "to invite disaster" = to bring misfortune upon oneself), 誤解を招く (gokai o maneku, "to invite misunderstanding"). The phrase suggests that one's actions actively summon consequences. And the famous 招き猫 (manekineko, "beckoning cat") — the Japanese ceramic cat figurine with one paw raised, beckoning prosperity into shops and homes; raised left paw invites customers, raised right paw invites money. The figurine's name uses this exact verb maneku.

Memory aid: hand (扌) plus voice-summons (召) — both calling and gesturing = inviting / beckoning.
