Pronunciation

  • 4th-century AD Koine: /ˈpsyl.la/[1]
  • 10th-century Byzantine: /ˈpsyl.la/[1]

Forms

ψῠ́λλᾰ (psúlla) f (genitive ψῠ́λλης); first declension[1] Masculine ψύλλος (psúllos) in Epicharmus and Aristotle, which the Atticist Phrynichus rejected in favour of ψύλλα.[2]

Etymology

It is inherited from Proto-Indo-European *plús-ih₂ (“flea”), with metathesis to *psuli-, perhaps by association with ψῆν (psên, “to rub”).[3][1] Cognate with Sanskrit प्लुषि (plúṣi), Old Armenian լու (lu), Lithuanian blusà, Latin pūlex, Old English flēah and Albanian plesht.[3][1]

The name of the flea varies irregularly across the Indo-European languages, and Beekes explains the variants as euphemistic, playful or folk-etymological distortions, perhaps already in the parent language.[3] LSJ sets up four different starting forms.[2]

Earliest recorded meaning

It is first found in Aristophanes' Clouds, meaning a flea.[2][4]

Semantic evolution

Aristophanes and Xenophon use it for the flea, and Aristotle also for a venomous spider.[2][5] Theophrastus applies it to an insect that attacks radishes and chickpeas, and Aelian to a kind of monkey.[2][5] The masculine ψύλλος, attested in Epicharmus and Aristotle, was condemned by Phrynichus.[2]

Modern Greek ψύλλος (psýllos) continues the masculine.[6][7]
