Making soft, murmuring sounds like a dove or pigeon, often expressing contentment or affection.
From Middle English 'cowen', imitative in origin—it literally sounds like the word describes, making it onomatopoeia from Old English roots.
Cooing is one of the oldest sounds humans recognize as 'sweet'—babies and doves make nearly identical soft sounds, which is why the word works across species to mean gentle contentment.
Cooing is often infantilized or gendered—associated with soft, feminine vocalization or used to describe women's speech dismissively ('cooing' vs. 'speaking'). Carries connotations of reduced intellectual content.
Use specifically for bird sounds or described infant comfort. Avoid applying to adult speech, particularly women's speech, as it diminishes credibility.
