| Part | Meaning | Language | Note |
|---|---|---|---|
| cyrt- | curved, arched | Greek (cyrt, -o) | from Greek kyrtos (κυρτός), bent or curved |

| -nyx | claw (also: night, in some entries) | Greek (nyx, nyct, -o) | here from Greek onyx/nyx in the sense of claw or talon, as used in ornithological genus names |
Cyrtonyx is a single-word genus name treated as a Latin feminine noun (following the grammatical gender of Greek compounds ending in -nyx). It is a Greek nominal compound: the adjectival stem cyrt- (curved) modifies the head noun -nyx (claw/talon), yielding 'curved claw.' The name refers to the distinctively curved claws of the Montezuma Quail, which the bird uses to rake the ground for food.
Pronunciation
- sir-TOH-niks Penult stressed: the penult vowel 'o' is long (followed by a single consonant then a short final syllable), placing stress on the penult '-to-'
Other readings
cyrt- + onyx (full form): 'curved nail/claw' — onyx is the fuller Greek root; nyx here is its shortened combining form, as is standard in zoological nomenclature
The dictionary confirmed 'cyrt' (curved/arched, Greek) and 'nyx'/'nyct' (claw/night, Greek) are both in the dictionary. The segment -nyx is the clipped combining form of Greek ὄνυξ (onyx), meaning nail, claw, or talon. In many bird genus names (e.g. Elanus, Harpagus) the claw sense is standard. Cyrtonyx montezumae (Montezuma Quail) is the type species; the curved claws are an adaptation for digging up bulbs and tubers. Initial 'C' before 'y' is pronounced 's' per the palatal-c rule (c = 's' before y, e, i, ae, oe).
