What does amphibolous mean?
The definition of amphibolous
Am*phib”o*lous, a.
Etym: [L. amphibolus, Gr. 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.
