鳴

An associative compound:

口 (“mouth”) - indicates the act of making sound.

鳥 (“bird”) = indicates the source (birds/animals).

Together: “a bird (or animal) making sound with its mouth.”

Common compounds in Korean:

悲鳴 (비명) - a scream, a shriek;

共鳴 (공명) - resonance, sympathy;

鳴呼 (명호) - “alas!” (exclamation in classical texts);

鳴禽 (명금) - songbirds.

In literature, often used metaphorically for voices or expressions of feeling.

Although by form and meaning it seems natural to classify under the mouth radical (口部), in dictionaries it is actually listed under the bird radical (鳥部).
