Amphibolous \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.
