Syn.
Plausible, Specious.
Plausible denotes that which seems reasonable, yet leaves distrust in the judgment. Specious describes that which presents a fair appearance to the view and yet covers something false. Specious refers more definitely to the act or purpose of false representation; plausible has more reference to the effect on the beholder or hearer. An argument may by specious when it is not plausible because its sophistry is so easily discovered.
