yoo-DIH-nuh-miss
Genus

Literally: Good power
| Part | Meaning | Language | Note |
|---|---|---|---|
| eu- | good, well | Greek (eu) | Standard Greek prefix |
| dynam- | be able; power, energy | Greek (dyn, -am, -amo, -ast) | Stem of Greek δύναμις (dynamis); third-declension noun |
| -ys | nominative singular ending of third-declension -ις nouns | Greek | Ending of δύναμις rendered in Latin letters as -ys; not an independent root |
Eudynamys is a single compound Greek noun adopted into New Latin as a feminine genus name. The prefix eu- (good, well) modifies the noun stem dynam- (power), from δύναμις (dynamis). The nominative singular ending -ys completes the word. The name stands alone; species epithets in the genus must agree grammatically with the feminine gender.
Pronunciation
- yoo-DIH-nuh-miss Four syllables: eu-dy-na-mys. Penult 'na' has a short vowel followed by only one consonant, so stress does not fall there. Stress moves to the antepenult 'dy'. The antepenult vowel y (= i) is not a diphthong, not u, and not followed by two vowels with e/i/y first, so it is short: 'ih'. Final -ys = short 'iss'.
Commonly: yoo-DY-nuh-miss (many ornithologists use a long-i glide in the stressed syllable, as in 'dye'; this Anglicised form is widely accepted in practice)
Other readings
A superficial segmentation eu- + dynam- + -mys could read the final three letters as the Greek root mys (muscle or mouse), but this is a coincidental overlap. The full word δύναμις (dynamis) ending in -ys is the correct and contextually meaningful reading for a bird genus name.
The tool the dictionary detected 'mys' (Greek: muscle or mouse) as a coincidental substring match at the end of the word. This reading is rejected: the final -ys is the nominative singular ending of δύναμις (dynamis) and carries no independent meaning. The ending -ys is not listed as a standalone entry in the dictionary; it is treated here from general knowledge of Greek third-declension morphology (confidence: high). Eudynamys Vigors & Horsfield, 1827 is the genus of koels (family Cuculidae), birds known for their loud, powerful calls — consistent with the meaning 'great power'.
