Genus

Literally: mountain ostrich
| Part | Meaning | Language | Note |
|---|---|---|---|
| oreo- | mountain | Greek (ore, -o) | combining form oreo-, from Greek oros/oreos |
| struth- | an ostrich (ultimately from Greek strouthos, 'sparrow; ostrich') | Latin (=struthio, -n) | stem struth- taken from struthio; the -io ending is dropped before the Latin nominative -us |
| -us | Latin nominative singular masculine ending | Latin | gives the genus name its grammatical gender: masculine |
A single compound genus name built from the Greek combining form oreo- (mountain) joined directly to the stem of Latin struthio (ostrich), with the standard Latin masculine nominative singular ending -us. The whole word functions as a masculine Latin noun in the nominative case. No connecting vowel is needed because oreo- already ends in a vowel. Oreostruthus is the mountain firetail finch of New Guinea, aptly named for its highland habitat.
Pronunciation
- or-ee-oh-STROO-thus Penult rule 4: the penult vowel is 'u', and the rule states most penults with vowel u are stressed; stress falls on 'struth'.
Other readings
A possible but implausible alternative would be to read ore- as the Latin root os/oris (mouth) in a different form, but the -o- combining vowel and the context of a highland bird make Greek ore- (mountain) the clear choice.
struthio is listed in the dictionary as Latin, but the word is itself a borrowing from Greek strouthos / strouthion (sparrow; ostrich), so the name is effectively a Greek–Greek compound in meaning, even though the dictionary form is Latin. Oreostruthus is a real genus of finch (mountain firetail, family Estrildidae) endemic to the highlands of New Guinea, making the 'mountain' element especially apt. The -th- in struthus is treated as a single consonant (Greek theta transliterated) for stress purposes, keeping the penult short by nature but stressed by rule 4 (penult vowel u).
