From the French adjective and noun desinfectant, which is derived from a combination of the Latin prefix dis- (indicating a taking away or undoing) and the Latin verb inficio, inficere, infeci, infectum (dye, tint, discolor, taint, poison), which is a combination of the Latin prepositional prefix in- (in) and the Latin verb facio, facere, feci, factum (make).
