penguin (English)
Where does "penguin" come from?
First attested in the 16th century, the English word 'penguin' originally referred to the great auk of the Northern Hemisphere before it was extended to the unrelated flightless birds of the Southern Hemisphere[1]. The exact source of the name remains uncertain[1]. One prominent theory derives it from Welsh, combining 'pen' meaning 'head'[1][2] and 'gwyn' meaning 'white'[1][6]. Another proposed origin traces it to Latin 'pinguis', meaning 'fat'[1][3].
Open questions
- The true origin of the word is unresolved, with competing theories linking it either to Welsh elements meaning white head or to Latin meaning fat. [1] [2] [3] [6]
- The Latin word pinguis may itself reflect an uncertain contamination between the Proto-Indo-European roots *peyH- and *bʰenǵʰ-. [1] [3]
