A disadvantage or unfavorable condition; the opposite of advantage or benefit.
From dis- (prefix meaning 'opposite of') + vantage (from advantage, derived from Old French avantage). This is a variant or archaic form of 'disadvantage'.
This is an archaic word that shows how 'dis-' used to be used more creatively—'disvantage' was an older way to say 'disadvantage,' but language settled on the 'dis-' prefix added to 'advantage' instead.
