Leptocoma
lep-TOH-koh-muh
Genus
the fine-haired one; slender-plumed
Literally: slender hair (fine-plumed)
| Part | Meaning | Language | Note |
|---|---|---|---|
| lepto- | fine, slender | Greek (lept, -o) | combining form lepto-, joined to the following root with its inherent -o- |
| -coma | hair | Greek (via Latin form) (=coma, -to) | Dictionary entry is under Latin but the 'hair' sense comes from Greek κόμη (komē); the '(G): deep sleep' sense is unrelated and does not fit here. In ornithological genus names -coma regularly means 'plumage/hair'. |
A single-word genus name formed from two Greek elements joined by the combining vowel already present in lepto-. Coma functions as the head noun (hair/plumage) and lepto- is the modifier (slender/fine). The whole compound is treated as a Latin feminine noun (standard for genus names ending in -a).
Pronunciation
- lep-TOH-koh-muh Four syllables: lep-to-co-ma. Penult is 'co': short vowel followed by only one consonant (m), so penult stress conditions are not met. Stress falls on the antepenult 'to'. Antepenult vowel is short (single consonant follows before another vowel).
Other readings
lepto- + -coma (deep sleep): 'slender sleep' — grammatically possible but makes no biological sense and is rejected.
Leptocoma is a genus of sunbirds (family Nectariniidae), and the name aptly describes their fine, slender plumage. The dictionary entry for =coma lists the 'hair' meaning under Latin, but the word is ultimately Greek κόμη; in New Latin zoological nomenclature it is used freely as a combining form meaning 'hair' or 'plumage'. The -oma (tumor) and toc- (birth) matches are positional accidents and play no role in this name.
