A young swan, especially one that is not yet fully grown or mature.
From Latin 'cygnus' (swan) + Old French diminutive '-et'. The word has been used in English since at least the 14th century to refer to baby swans.
Just like we call baby dogs 'puppies' and baby cats 'kittens,' we call baby swans 'cygnets'—and they're actually quite gray and fluffy before turning into those beautiful white adults!
