\Am*phib"o*lous\, a. [L. amphibolus, Gr. ? thrown about, doubtful. See {Amphibole}.] 1. Ambiguous; doubtful. [Obs.] Never was there such an amphibolous quarrel -- both parties declaring themselves for the king. --Howell. 2. (Logic) Capable of two meanings. An amphibolous sentence is one that is capable of two meanings, not from the double sense of any of the words, but from its admitting of a double construction; e. g., ``The duke yet lives that Henry shall depose.'' --Whately.
