| -atus | provided with, having, characterized by (adjectival suffix forming past-participle adjectives from nouns) | Latin (-atus, -ata, -atum) | Standard Latin adjectival suffix; not listed as a standalone entry in the dictionary but universally attested; nominative masculine singular agrees with a masculine genus noun |
Ocreatus is a single-word genus name formed from the Latin noun ocrea ('a legging') plus the productive Latin adjectival suffix -atus ('furnished with'), giving the meaning 'provided with leggings.' It functions as a substantivized Latin adjective of masculine gender, treated as a noun in apposition to itself as the genus. The name alludes to the conspicuous fluffy white leg-puff tufts of the booted racket-tail hummingbird (Ocreatus underwoodii), which resemble a soldier's greaves or leggings.
Pronunciation
- ok-ree-AY-tus Penult stress: the penult syllable contains the vowel 'a' from the Latin suffix -atus, which is long (ā) in classical Latin — rule 4 (long penult vowel).
Other readings
A minority reading could derive the first element from Greek ocr- / ocri- (pale; ridge, summit), but the Latin ocrea = 'legging' is clearly the correct etymology given the bird's morphology.
The suffix -atus is not listed as a standalone entry in the dictionary tool but is one of the most productive and well-attested Latin adjectival suffixes; confidence is high. Ocreatus is a hummingbird genus erected by Gould (1846), containing the booted racket-tail; the name directly references the bird's boot-like leg plumes. The Latin word ocrea also gives English 'greave' via translation; it was used in Roman military contexts for the metal shin-guard worn by soldiers and gladiators.
