|---|---|---|---|
| drom- | Run; running; a race | Greek (drom, -a, -ae, -aeo, -i, -o, =us) | Core verbal root |
| -aius | Of or characterized by; forming adjectives or agent nouns from a root | Greek (-αῖος (Latinized -aius)) | Standard Greek adjectival suffix Latinized; not a standalone dictionary entry but confirmed by the dictionary's inclusion of 'dromaius' as a terminal form of the drom- entry |
Dromaius is a single-word genus name, a substantivized Greek adjective Latinized into the first/second-declension masculine nominative singular form (-us ending). It stands alone as a noun in apposition meaning 'the running one' or 'the swift runner', coined by Vieillot (1816) for the emu, a large cursorial bird.
Pronunciation
- dro-MY-us Penult rule 2: the penult syllable contains the diphthong 'ai' (= long i, 'eye'), so stress falls on the penult.
Other readings
One might theoretically read dro- + mai- (Greek mai, 'a kind of crab') + -us, but this is semantically implausible and contradicted by the dictionary's own listing of 'dromaius' as a form of drom-.
The suffix -aius (-αῖος) is not a standalone entry in the dictionary but is a well-attested Greek adjectival suffix; confidence remains high because the dictionary explicitly lists 'dromaius' as a recognized terminal form of the drom- root entry. Coined by Vieillot (1816); the name aptly references the emu's cursorial (ground-running) lifestyle.
