Pronunciation
- SEP-fus Penult rule 1: a two-syllable word is always stressed on the penult. The c before e is pronounced 's'; the double ph renders as 'f'.
The genus was established by Pallas (1769) for the black and pigeon guillemots (family Alcidae). The Greek κέπφος is attested in classical authors (e.g. Aristotle) for a light, petrel-like seabird; its secondary meaning 'simpleton' referred to the bird's reputedly witless behaviour near vessels. ph in cepphus is the Greek letter phi, rendered as the English 'f' sound.
