Aegolius is a monomial genus name (a single uninomial at generic rank). It is a New Latin Latinization of the ancient Greek noun αἰγώλιος (aigōlios), inflected with the standard Latin nominative singular ending -us. The core root aig- (αἴξ, αἰγός = goat) carries the semantic weight; the suffix -ōlios made the whole word a noun used as a name for a particular owl in ancient Greek zoological writing. As a genus name it stands alone without an epithet in this query.
Pronunciation
- ee-go-LEE-us Four syllables: Ae-go-li-us. The penult is 'li', whose vowel i is followed by the vowel u opening the final syllable; a vowel followed by another vowel is long. A long penult draws the stress (Penult Rule 4). The diphthong ae = 'ee'; final -us has a short u.
Commonly: ee-GOH-lee-us (antepenult stress, treating -lius as a single consonantal-glide syllable '-lyus', giving three syllables Ae-go-lius; common in birding circles)
Other readings
Some authorities treat the full form αἰγώλιος as an indivisible ancient proper name for the bird, with only a folk-etymological link to 'goat' (perhaps the owl was thought to haunt goat pastures, or there is an echo of the goat-sucker myth paralleling Caprimulgus). Under that reading, Aeg-ōlios is not a transparent compound but a lexicalised bird name simply borrowed into Latin nomenclature.
The Greek suffix -ōlios (-ώλιος) is not entered in the dictionary as an independent root; its identification rests on general knowledge of Greek word-formation (confidence: medium). Aristotle uses αἰγώλιος in Historia Animalium 8.3 (563b) for a small nocturnal bird; the exact species he meant is debated but the name was formally adopted by Kaup (1829) for the genus containing the Boreal Owl (Aegolius funereus) and allies. The root aig- (dictionary entry 'aig') also carries the meaning 'a waterfowl', but the goat sense is the standard etymology cited for this genus name.
