Mentocrex
MEN-toh-kreks
Genus
the chin rail (a bird with a distinctive chin)
Literally: chin rail
| Part | Meaning | Language | Note |
|---|---|---|---|
| mento- | chin | Latin (mentum, mento-) | stem of Latin mentum (chin); connecting form mento- before consonant |
| crex | a rail (bird in the family Rallidae); crake | Greek | used as a genus-forming element for rails and crakes; final element, no connecting vowel needed |
A compound genus name formed from the Latin combining form mento- (chin, from mentum) joined directly to the Greek noun crex (rail, crake). The whole word functions as a Latin noun of masculine gender in the nominative singular, as is standard for genus names. The combination is a Greco-Latin hybrid (Latin head modifier + Greek head noun), which is acceptable in zoological nomenclature. The name presumably refers to a distinctive chin marking or colouration of the bird.
Pronunciation
- MEN-toh-kreks Antepenult stress: the penult vowel (o) is short and followed by only one consonant (cr-) before the final syllable, so stress falls on the antepenult (MEN-).
Other readings
ment- (Latin mens/mentis, mind) + o- (connecting vowel) + crex — phonetically possible but semantically implausible for a bird genus; the chin reading is strongly preferred
Mentocrex is a genus of rails (family Rallidae) endemic to Madagascar, erected by Olson (1996). The name alludes to the pale chin/throat patch characteristic of these birds. The combination of Latin mento- with Greek crex is a deliberate Greco-Latin hybrid, a common practice in zoological nomenclature when a well-established Greek genre-name (crex) is modified by a Latin descriptor. The dictionary confirmed both 'mento' (Latin, chin) and 'crex' (Greek, rail) in the dictionary.
