| Part | Meaning | Language | Note |
|---|---|---|---|
| pleg- | a blow, strike; a sickle | Greek (pleg, -a, -e, -i, =ia, -o) | core root; the sense 'sickle' is the one operative here |
| -ad- | Greek noun-stem–forming suffix, creating a concrete noun from the root | Greek | same suffix seen in Ilias→Iliad-, dryas→dryad-; not a separate dictionary entry but a regular Greek morpheme |
| -is | Latinized Greek nominative singular ending | Greek | the full Greek word is πληγάς, gen. πληγάδος (plegás, plegádos); Latinized by taking the genitive stem plegad- and adding -is as the nominative |
Plegadis is a single-word genus name. It is a Latinized third-declension Greek noun (stem plegad-), feminine in grammatical gender, used as a standalone genus noun. It is not paired here with a specific epithet. The name alludes directly to the sickle-shaped, decurved bill shared by all species in the genus.
Pronunciation
- PLEG-uh-dis Antepenult stressed: the penult vowel 'a' is short and followed by only one consonant (d), making the penult light, so stress retreats to the antepenult 'Ple-'.
Other readings
A minority reading could try to split pleg- + gad- (Greek gadus, a kind of fish) + -is, but this yields no biological sense and is contradicted by the well-attested Greek word πληγάς meaning 'sickle'.
The Greek noun πληγάς (plegás, gen. plegádos) meaning 'sickle' is directly attested and is the standard etymology accepted for this genus, coined by Kaup 1829. The -ad- stem suffix and the -is nominative ending are regular Greek and Latinized-Greek morphology respectively; neither appears as a standalone dictionary entry, so in_dictionary is set to false for those segments, but confidence remains high. The dictionary entry for pleg- (id 5052) confirms the meaning 'a blow, strike; a sickle', fully supporting the segmentation.
