Pronunciation

  • Classical: [ɡɛ.nɛˈtiː.wʊs][1]
  • Ecclesiastical: [d͡ʒe.neˈtiː.vus][1]

Forms

genetīvus (feminine genetīva, neuter genetīvum); first/second-declension adjective[1]

Etymology

It is from Latin gignō (“to beget”) + -īvus, built on the participle genitus.[2][3][1] In grammar it is a calque of Ancient Greek γενική (genikḗ).[1]

Earliest recorded meaning

Ovid uses it of a form one had at birth, when Tiresias regains his former shape, “genetivaque venit imago”.[2][4]

Semantic evolution

Macrobius quotes an older author for an altar of Apollo Genetivus at Delos, the god as begetter: Varro according to the OLD, Cato according to L&S.[2][5] Suetonius has genetivae notae for birthmarks, and Ovid uses it of names belonging to a family.[5]

In grammar, genetivus casus and the noun genetivus named the genitive case from Quintilian on.[2][5] Varro had called this case patricius.[5] L&S insists on the spelling with e.[5]

Timeline

  • c. 35–95/96 AD – Quintilian uses it for the genitive case.[2][4]
