‘耳语’ literally means ‘ear speech’—combining 耳 (ěr, ‘ear’) and 语 (yǔ, ‘speech’ or ‘language’). It refers to speaking very softly, often with lips close to someone’s ear, so only that person can hear. Unlike general quiet talking, 耳语 implies intentional secrecy, intimacy, or discretion—common in conversations between friends, lovers, or colleagues sharing confidential information.

This word functions both as a noun (e.g., ‘a whisper’) and as a verb (e.g., ‘to whisper’), though the verbal usage usually requires a complement like ‘道’ or ‘说’, as in ‘耳语说道’. It carries a gentle, sometimes tender or conspiratorial tone—not harsh or urgent like shouting or hissing. You’ll hear it in everyday settings: classrooms, theaters, hospitals, or even nature documentaries describing animals communicating quietly.
