11th cent. From Latin vita 'id.'
Either from Proto-Italic *wī́wita 'id.,' from Proto-Indo-European *gwi̯H-u̯o-t-ā-, or from Proto-Italic *wī́ta- 'id.,' from Proto-Indo-European *gwi̯H-t-h2 (both are phonologically possible, as there is not enough phonological data in Latin to draw a conclusion). In either case, both potential ancestors derive from the root *gwei̯H- "to live."
Also the origin of the surnames Vida, Vidal, and Vidales.
