铃
líng · HSK 5
bell
🔔 铃 = 钅(metal) + 令 (líng, command) — a metal thing that commands attention
The 钅 radical marks metal objects; 令 (líng) both gives the sound and hints at function — a small metal piece that summons or signals. Same 令 phonetic appears in 龄, 零, 玲.
铃 — metal radical 钅 + order/command 令
A semantic-phonetic compound: 钅 (metal) signals the meaning, while 令 (lìng) hints at the sound, shifted to líng. Originally referred to small metal bells that ring when shaken, and by extension any bell-like object.
