Etymology tree Proto-Celtic *kʷennom Proto-Brythonic *penn Welsh pen? Proto-Indo-European *weyd-der.? Proto-Celtic *windos Proto-Brythonic *gwɨnn Welsh gwyn? Proto-Indo-European *peyh₂-der. Proto-Indo-European *bʰenǵʰ-influ.? Latin pinguisder.? English penguin Uncertain. First attested in the 16th century in reference to the auk of the Northern hemisphere; the word was later applied to the superficially similar birds of the Southern hemisphere (as was woggin). Possibly from Welsh pen (“head”) and gwyn (“white”), or from Latin pinguis (“fat”). See citations and the Wikipedia article. Sense 3 originates from the often black-and-white habit worn by nuns, which resemble the bird's colors.
