Pronunciation

  • IPA (Classical): [fiː.liˈas.tɛr][1]
  • IPA (Ecclesiastical): [fi.liˈas.ter][1]

Forms

fīliaster m (genitive fīliastrī, feminine fīliastra); second declension[1]

Etymology

It is from Latin fīlius (“son”) + -aster.[2][3][1] De Vaan derives ⟨fīlius⟩ from Proto-Italic *fīlio- (“son”), from an adjective Proto-Indo-European *dʰh₁i-l- (“suckling, child”), cognate with Faliscan ⟨fileo⟩ “son” and Venetic ⟨filia⟩ “daughter”.[4]

Earliest recorded meaning

Lewis & Short and Gaffiot cite inscriptions, and Wiktionary calls it Late Latin.[5][6][1]

Semantic evolution

It meant a stepson, the same as prīvignus, with a feminine fīliastra “stepdaughter”.[2][5][6]

Medieval Latin used it for a stepson, a bastard son, a grandson by a daughter, and a son-in-law.[7] British Medieval Latin glossed it with Old English stēopsunu.[8] It survives as Italian figliastro, French fillâtre, Spanish hijastro and Romanian fiastru.[1]

Timeline

  • 2nd century AD – Köbler dates its earliest glosses to this period.[9]
