Venetian

From Latin Venetianus (“Venetic; Venetian”), from Venetia (“lands of the Veneti; Venice, Veneto; Armorica”) + -anus (“-ian”), from Veneti + -ia. In the case of the Veneti of northern Brittany, derived from Gaulish Uenetoi (“the friendly ones, the kinsmen”), from Proto-Celtic *wenet, a derivation from *wenyā (“kindred”). In the case of the Veneti of northeastern Italy, of uncertain origin but presumably taken from a Venetic endonym, possibly Illyrian or Celtic. Equivalent to Veneto or Venetia +‎ -ian.
