鳴る
なる · naru · JLPT N4 · verb-godan
to sound
🔔 鳴 = mouth 口 + bird 鳥: a bird's cry, so any sound ringing out
The kanji joins 口 (mouth) and 鳥 (bird): originally a bird calling. With る it became the intransitive verb for things that sound on their own: bells, phones, alarms, thunder. Sound hook: naru is the bell's own gnarl-oo, no one rings it.
