A Greek compound adjective or agent noun Latinized as a masculine second-declension noun: phil- (loving) + hetairos (companion) + -us (Latin nom. sg. ending). The whole word means 'one who loves companions' or 'companion-loving.' It refers to the extreme colonial sociality of the Sociable Weaver. The name also echoes the historical Hellenistic figure Philetaerus (founder of the Attalid dynasty of Pergamon), whose name has the same Greek roots.
Pronunciation
- fil-eh-TAY-rus Penult rule 2: the penult syllable 'tai' contains the diphthong ai (= long 'ay'), so the penult is stressed.
Other readings
The name could be read as a direct Latinization of the personal name Philetaerus (Φιλέταιρος), rather than a fresh coinage from the roots — the meaning is identical either way.
The root hetaer (hetairos) is in the dictionary under 'hetaer, -a, -o' (Greek, 'a companion'); the form appears here as -etair- with the initial h dropped and the Greek ai diphthong preserved in spelling. The genus Philetairus socius (Sociable Weaver, family Ploceidae) was named by Andrew Smith in 1837, alluding to the bird's extraordinary communal nesting behaviour.
