Literally: Shifting helmet; wind-like helmet
| Part | Meaning | Language | Note |
|---|---|---|---|
| coryth- | A helmet | Greek (cory, -d, =s) | Oblique stem of κόρυς (corys); nominative corys, genitive corythos — the -th- appears in all non-nominative forms |
| aeol- | Quick-moving, shifting; also alludes to Aeolus, god of the winds (Greek mythology) | Greek (aeol, -i, -o) | Both the descriptive adjective sense (quick-moving, shifting) and the mythological reference (Aeolus) are attested in the dictionary under the same form |
| -a | Feminine noun ending | New Latin feminine singular nominative termination, establishing the genus as grammatically feminine |
Corythaeola is a New Latin feminine noun coined from two Greek roots joined without a connecting vowel (the stem coryth- ends in a consonant and aeol- begins with a vowel, so no -o- is needed). The whole word functions as a single genus name in the nominative singular. The oblique stem coryth- (from κόρυς, helmet) serves as the head concept, and aeol- (shifting, wind-like) acts as a descriptive modifier compounded directly onto it. The final -a marks it as a feminine Latin-form noun. As a genus name it stands alone at this rank; the specific epithet cristata (crested) in the full binomial Corythaeola cristata agrees with it in the feminine.
Pronunciation
- ko-rith-EE-oh-luh Antepenultimate stress: the penult vowel -o- is short (followed by only one consonant, -l-, with no diphthong or long-vowel ending), so stress retreats to the antepenult -ae-, which is a diphthong (ae = long e, 'ee') and therefore long.
Other readings
cory- (nominative stem, helmet) + th as a transitional consonant + aeola — less likely because the -th- is better explained by the natural Greek oblique stem corytho-/coryth-
aeol- read purely as the mythological Aeolus (god of winds) rather than the appellative adjective — both meanings are in the dictionary and both are biologically apt for a large, crest-waving bird
The -th- in coryth- is not a separate morpheme; it is the stem-final consonant of Greek κόρυς (genitive κόρυθος, korythos), regularly exposed when a suffix beginning with a vowel is attached. The dictionary lists aeol under both a Greek appellative entry (quick-moving, shifting) and a Greek mythology entry (Aeolus, god of the winds); both senses are relevant and likely intentional in the coinage. The final -a is a New Latin feminine ending, not found as a separate dictionary entry; marked in_dictionary false but confidence high as standard practice.
