The Italian term is derived from the Latin word "vernaculus" (like the German "Vernatsch"; see under Schiava) and means "native" or "from here" or autochthonous. According to a second theory, the name is derived from "verrum" (boar = wild boar), because in the Middle Ages these animals often invaded the vineyards and feasted on the grapes. And according to a third theory, the commune of Vernazza in the Cinque Terre area of Liguria is called Vernazza, but there is no evidence of this. In any case (as in the case of Lambrusco, Malvasia, Muscatel and Trebbiano) it is not a single grape variety, nor is it a family of grape varieties, but the neutral term is used in the name/synonym for many white and red grape varieties which are genetically clearly different. The numerous Vernaccia synonyms are sometimes given differently in the sources (e.g. Wine Grapes and VIVC catalogue) or assigned to different varieties:
