Uncertain. Perhaps a stative form from the Proto-Indo-European root *weǵ- (“to be lively”), possibly via Proto-Italic *wegēō. De Vaan and Sihler relate the term to vegeō, which De Vaan argues is indicative of an original adjective *weg-o- (“active, alive, awake”), which De Vaan suggests may be the source of the Latin term. The *-i- is unexpected in the Latin form.
vigeō (present infinitive vigēre, perfect active viguī); second conjugation, no passive, no supine stem
