‘共鸣’ literally means ‘sounding together’—‘共’ (gòng) means ‘together’ or ‘shared’, and ‘鸣’ (míng) means ‘to make a sound’ or ‘to ring out’. Originally a physics term describing how one vibrating object causes another to vibrate at the same frequency, it’s now used almost exclusively in figurative, emotional contexts. It describes a deep, spontaneous sense of shared feeling or understanding between people—like when a story, speech, or piece of music stirs strong recognition or empathy in a listener.

This word is common in literary, artistic, and psychological discussions, as well as everyday conversation about personal connections. It implies authenticity and emotional alignment—not just agreement, but a visceral, often moving, mutual resonance. You’ll hear it in reviews (e.g., ‘the film evoked strong resonance’), therapy settings (e.g., ‘therapist-client resonance’), and social commentary (e.g., ‘a generation’s shared resonance with economic uncertainty’).
