Certhionyx
ser-THEE-oh-niks
Genus
tree-creeper with claws; claw of a tree-creeper
Literally: tree-creeper claw
| Part | Meaning | Language | Note |
|---|---|---|---|
| certhi- | a tree creeper | Greek (certh, -i) | combining form; the -i- is the combining vowel of the root, not a separate connector |
| -onyx | a claw, nail | Greek (=onyx, -i) | used here as a standalone terminal element; also means 'fingernail, talon' |
A compound of two Greek roots joined directly: certhi- (combining form of certh, 'tree creeper') + onyx (nominative singular, 'claw'). The whole word functions as a noun in apposition — a single uninflected genus name treated as a Latin noun (masculine by convention). It describes the bird's possession of tree-creeper-like talons, alluding to the strong curved claws used for clinging to bark or flowers.
Pronunciation
- ser-THEE-oh-niks Four syllables: Cer-thi-o-nyx. Penult is 'o', a short vowel followed by only one consonant (n), so penult stress is not triggered. Antepenult 'thi' has vowel 'i' followed immediately by another vowel ('o'), making it long — but stress falls on the antepenult regardless of its quantity when the penult is light. Result: antepenult 'thi' is stressed.
Other readings
A minority reading might try to split certhi-on-yx, assigning -on- to the Greek suffix -ion (diminutive) and -yx to nyx ('night' or 'puncture'), giving something like 'little creeper of the night / puncture', but this is far-fetched and the straightforward certh + onyx is strongly preferred given that the type species (Certhionyx variegatus, the pied honeyeater) has prominent, curved claws.
Certhionyx is a genus of Australian honeyeaters (family Meliphagidae); the type species is Certhionyx variegatus (pied honeyeater). The root certh (Greek: a tree creeper) is the same root underlying the genus Certhia (true tree creepers, family Certhiidae); the name thus draws a morphological analogy between the honeyeater's clinging feet and those of a tree creeper. 'c' before 'e' is soft, giving 's'; 'th' is the Greek theta, pronounced as in 'thin' (θ); final 'yx' = 'iks'.
