Thectocercus
thek-toe-SER-kus
Genus
the sharpened-tail (one)
Literally: sharpened tail
| Part | Meaning | Language | Note |
|---|---|---|---|
| thect- | sharpened | Greek (thect, -o) | combining form thecto- used before consonant; refers to a pointed or sharpened quality |
| -o- | connecting vowel | ||
| cerc- | the tail | Greek (cerc, -o, =us) | here in the sense of tail, as in cercus (tail appendage); the separate entry cerc, -i, =is (a rod; a kind of poplar) is less fitting in a zoological context |
| -us | Latin nominative singular masculine ending | Latin | standard gender-marking suffix for Latin-form genus names |
A single compound noun used as a genus name, treated as Latin masculine singular. The Greek stem thecto- (sharpened) modifies the Greek head noun cercus (tail), yielding an endocentric compound: 'the one with a sharpened tail.' The -o- is a Greek connecting vowel. The whole word is given a Latin -us ending following standard New Latin practice for genus names.
Pronunciation
- thek-toe-SER-kus Penult rule 5: penult vowel 'e' in 'cer' is short but is followed by two consonants (r + c), so the penult is stressed.
Other readings
thec- (case, box) + -to- (birth, from toc-) + cerc- + -us: 'box-birth-tail,' which is semantically incoherent and almost certainly wrong. The thect-o- (sharpened) reading is strongly preferred and fits the parrot genus (pointed tail feathers).
Thectocercus is a genus of parakeets (family Psittacidae), split from Aratinga; the name alludes to the long, pointed tail feathers characteristic of these birds. The root thect-/thecto- ('sharpened') is distinct from thec-/theca ('a case or sheath'), though both appear in the match list; context and position strongly favor thecto-. The entry cerc, -o, =us ('the tail') is the correct match here; the homograph cerc, -i, =is ('a rod; a kind of poplar') is a different word.
