Gold Rule

Subject omission

The subject (警報) is often omitted in context: 「鳴った！」(It sounded! / The alarm went off!)

Word Origin

警報 (keihō) combines 警 (warning) and 報 (report), meaning 'alarm' or 'warning'. 鳴る (naru) means 'to sound' or 'to ring'. The phrase literally means 'the alarm sounds'.

Usage Notes

Commonly used in emergency contexts. The verb 鳴る (naru) is intransitive here, indicating the alarm activates itself without external action.
