Onychoprion
oh-NIK-oh-pry-on
Genus
the clawed saw; a saw with claws — referring to the sharply clawed feet and blade-like bill of these terns
Literally: claw-saw
| Part | Meaning | Language | Note |
|---|---|---|---|
| onycho- | a claw, nail | Greek (onych, -o) | combining form with connecting vowel -o- |
| prion | a saw | Greek (=prion, -o) | head noun, standalone form; gives the genus its grammatical gender (neuter) |
A single Greek compound noun. The modifier onycho- (claw) is prefixed in its standard combining form to the head noun prion (saw). The whole word functions as a neuter Latin-treated genus name. Species epithets placed in this genus must agree with neuter gender (e.g. Onychoprion fuscatus).
Pronunciation
- oh-NIK-oh-pry-on Five syllables: O-NYCH-o-pri-on. Penult (pri) has a short vowel followed by only one consonant, so it is light. Stress therefore falls on the antepenult (NYCH) per the antepenult default rule.
Other readings
nyc- (night) + -ion (diminutive) is theoretically present in the letter string but leaves o- and -pr- unexplained and is rejected in favour of the clean onycho- + prion split.
Both roots (onych, -o and =prion, -o) are confirmed in the dictionary. The biological motivation for the name is the noticeably compressed, saw-ridged culmen and strong claws that distinguish these terns from allied genera. As a genus name coined by Wagler (1832) it stands alone; no author or year is included in the normalized name.
