Alectrurus
uh-LEK-troo-rus
Genus
rooster-tailed
Literally: cock's tail
| Part | Meaning | Language | Note |
|---|---|---|---|
| Alectr- | cock, rooster | Greek (alectryon) | stem alektryo- / alektr-, from ἀλέκτωρ (alektōr); combining form alectr- |
| -ur- | tail | Greek (ur, -o) | from οὐρά (ourá); combining form -uro- |
| -us | masculine singular nominative ending; marks a genus name treated as Latin masculine | Latin/New Latin (=us) | standard genus-name termination |
The name is a single Greek compound Latinized as a masculine noun in -us. The first element alectr- (cock/rooster) serves as a modifier to the head noun -ur- (tail), connected directly without a linking vowel because the root ends in a consonant cluster that flows naturally into -ur-. Literally 'rooster-tail', the compound describes a characteristic feature of the bird — the dramatically elongated outer tail feathers of the male. Both species bearing this name (fork-tailed flycatcher relatives) are indeed celebrated for their extraordinary tails.
Pronunciation
- uh-LEK-troo-rus Penult rule 5: the penult vowel (u) is short but followed by two consonants (r-r), so the penult 'roo' is stressed.
Other readings
alectr- could in theory be read as from Greek alexein (to defend) + ktein (to kill), giving 'killer-defender', but the ornithological context and the Latinized alectryōn (cock) make the rooster reading overwhelmingly more likely.
The root alectr- was confirmed in the dictionary under 'alectr, alectry' (Greek, cock/rooster). The root -ur- / -uro- was confirmed in the dictionary (Greek, tail). Alectrurus is a real South American bird genus (tyrant-flycatchers, family Tyrannidae) containing two species: A. tricolor (cock-tailed tyrant) and A. risora (strange-tailed tyrant), both males having spectacular tail feathers, consistent with the name. The penult syllable '-ru-' contains the vowel u followed by r+r (written as single r before the final -us, but phonologically the coda /r/ of '-rur-' and the onset /r/ of '-us' together constitute two consonants flanking the penult vowel, triggering penult stress).
