Where it comes from
From Middle English siren, from Old French sereine and Latin Sīrēn, Sīrēna, from Ancient Greek Σειρήν (Seirḗn). The mammalian sense was first attested in French in Dominique Bouhours, Les entretiens d'Ariste et d'Eugène, in 1671. The aquatic salamander sense was originally introduced by Linnaeus in 1766, for a genus of his reptiles.
