| Part | Meaning | Language | Note |
|---|---|---|---|
| trigono- | a triangle; triangular | Greek (trigon, -o) | combining form trigono- (trigon + connecting vowel -o-) |
| -o- | connecting vowel | links Greek stem to the New Latin terminal element | |
| -ceps | the head | New Latin (=ceps) | derived from Latin capit- (head); used as a terminal element in zoological genus names |
Trigonoceps is a uninomial genus name formed as a compound noun treated as Latin, feminine or masculine by convention. The Greek combining form trigono- (triangle) modifies the New Latin head-noun -ceps (head), yielding a compound meaning 'triangular head.' No species epithet is given here. The name refers to the distinctively triangular shape of the bare-skinned face and head of the White-headed Vulture (Trigonoceps occipitalis).
Pronunciation
- try-GON-oh-seps Four syllables: tri-gon-o-ceps. Penult is the bare connecting vowel 'o', a short vowel followed by a single consonant — none of the penult-stress conditions are met, so stress falls on the ANTEPENULT 'gon'. The antepenult vowel 'o' is short (followed by a single consonant then another vowel that is not e/i/y). The 'c' of '-ceps' becomes 's' before 'e'.
Other readings
No plausible alternative segmentation exists; tri- (three) + gono- (seed/knee) + -ceps (head) is grammatically possible but semantically nonsensical for this taxon.
Trigonoceps is the monotypic genus of the White-headed Vulture (Trigonoceps occipitalis), named by Brian Houghton Hodgson in 1853. The name alludes to the triangular outline of the bird's bare pink-and-blue face and broad, flat-topped head. The terminal element -ceps (NL, 'head') is recorded in the dictionary and traces to Latin caput/capit- (head); it appears widely in anatomical and zoological names (e.g. biceps, triceps, Accipiter). The connecting vowel -o- between the Greek stem and the New Latin suffix is standard practice even when the suffix itself is not Greek.
