Forms

neptia f (genitive neptiae); first declension[1] Also nepta.[2]

Etymology

It is from Latin neptis (“granddaughter”),[1][2] replacing it with a form that marks the feminine gender more clearly, perhaps on the model of avia (“grandmother”).[3]

It survives in the Romance languages: in Old French niece, the source of niece,[3][4] Old Occitan nepsa, Venetian netsa, Old Italian nezza,[3] Spanish nieta and Portuguese neta.[4]

Earliest recorded meaning

It is found first in an inscription of the 1st century AD (CIL XIII 8409), in the sense “granddaughter”.[3]

Semantic evolution

In the strict sense of a son's or daughter's daughter it is found only in inscriptions, mostly of the 2nd and 3rd centuries.[3] Inscriptions of the 3rd and 4th centuries use it more loosely for a brother's daughter, a niece,[3] and a glossary equates it with Greek Ancient Greek ἀνεψιά (anepsiá, “cousin”).[3] Both senses passed into Old French niece,[4] and the niece sense into Old Italian.[3]

Timeline

  • 1st century AD – An inscription (CIL XIII 8409) uses it for a granddaughter.[3]
  • 3rd century AD? – An inscription (CIL XIII 2237) uses it for a brother's daughter.[3]
  • 4th century AD – An inscription (CIL XIII 11737) uses it for a niece.[3]
  • c. 1300 – English nece, from Old French, continues it.[4]
