teh-rath-OH-pee-us
Genus
the marvelous-faced one
Literally: monstrous/wondrous face
| Part | Meaning | Language | Note |
|---|---|---|---|
| Terat- | monster, marvel, wonder | Greek (terat, -o) | stem of Greek τέρας (teras); combining form terato- |
| -o- | connecting vowel | ||
| -opi- | eye, face, appearance | Greek (op, -o) | stem of Greek ὤψ (ōps), genitive ὠπός; appears here as -opi- before the suffix |
| -us | nominative singular masculine ending | Latin | standard Latinized genus-name ending; grammatical gender: masculine |
A single Greek compound Latinized as a masculine noun. Terat(o)- (wonder/monster) + ōp- (face/appearance) + -us (Latin nominative ending). The two Greek roots are joined by the connecting vowel -o-, and the whole word is treated as a second-declension masculine Latin noun, as is conventional for genus names. The name alludes to the remarkably short, blunt face of the Bateleur eagle (Terathopius ecaudatus).
Pronunciation
- teh-rath-OH-pee-us Penult rule 4: the penult vowel 'i' in '-pi-' is long (it is followed by the vowel 'u'), so the penult is stressed — but wait: the syllables are te-rath-o-pi-us (5 syllables); penult = 'pi', antepenult = 'o'. The penult vowel 'i' is followed by another vowel 'u', making it long → stress falls on the penult '-pi-'.
Other readings
A minority reading splits the name as teras (marvel) + -opius from ops (resources/wealth, Latin), but this is almost certainly wrong; the Greek ōps (face/eye) fits perfectly and matches the bird's distinctive facial disc.
Terathopius is a monotypic genus erected by Lesson (1830) for the Bateleur eagle (T. ecaudatus). The name perfectly describes the bird's extraordinarily short face and bill relative to its large head. The dictionary confirmed 'terat' (Greek, monster/marvel) and 'op' (Greek, eye/face) in the dictionary. The connecting vowel -o- between terat- and -op- is standard Greek compounding practice.
