Eolophus
ee-OH-loh-fus
Genus
dawn-crested one — the bird with a rosy, dawn-coloured crest
Literally: dawn crest
| Part | Meaning | Language | Note |
|---|---|---|---|
| eo- | dawn; early | Greek (eo, =s) | used here in the sense of 'dawn(-coloured)', alluding to the galah's pale pink crest; appears as a free-standing prefix before the combining form of loph- |
| -loph- | a crest, tuft | Greek (loph, -i, -o, =us) | root used in its combining form; the final -us is the standard Latinised Greek masculine nominative singular ending (-lophus) |
| -us | masculine nominative singular termination | Latin | standard Latinisation of the Greek ending -ος (-os); marks the word as a Latin masculine noun |
Eolophus is a single compound noun formed from two Greek roots joined directly (no connecting vowel is needed because eo- ends in a vowel): eo- (dawn/early) + loph (crest) + -us (Latin masculine nominative). It stands alone as a genus name and is treated as a masculine Latin noun in the second declension. The name was coined by Bonaparte (1857) for the galah cockatoo (Eolophus roseicapilla), whose blush-pink crest evokes the colour of dawn.
Pronunciation
- ee-OH-loh-fus Four syllables: E / o / lo / phus. Penult 'lo' has a short vowel (Greek ŏ in λόφος) followed by only one consonant sound (ph = f), so the penult rule does not apply. Stress therefore falls on the antepenult, the second syllable 'o', giving ee-OH-loh-fus.
Commonly: EE-oh-loh-fus (some English speakers place stress on the first syllable, treating 'Eo-' as a single accented prefix)
Other readings
eol- (quick-moving; the winds) + -ophus: the dictionary does record eol, -i, -o meaning 'quick-moving; the winds', but this leaves -ophus unanalysable as a dictionary root and is far less convincing than eo- + lophus given the bird's conspicuous crest.
Eolophus roseicapilla (the galah or rose-breasted cockatoo) is the sole living species in this genus. The name neatly echoes the species epithet: roseicapilla means 'rosy-haired', and eolophus means 'dawn crest' — both reference the bird's distinctive pink plumage. The connecting vowel is absent between eo- and loph- because eo- already ends in a vowel; in Greek compound formation a connecting -o- is dropped before another vowel. ph is treated as a single consonant (f) for both pronunciation and stress purposes.
