AMPHIBOLOGICAL
Am*phib`o*log"ic*al, a.

Defn: Of doubtful meaning; ambiguous. "Amphibological expressions."
Jer. Taylor.
— Am*phib`o*log"ic*al*ly, adv.

AMPHIBOLOGY Am`phi*bol"o*gy, n.; pl. Amphibologies. Etym: [L. amphibologia, for amphibolia, fr. Gr. logia as if fr. Gr. amphibologie. See Amphiboly.]

Defn: A phrase, discourse, or proposition, susceptible of two interpretations; and hence, of uncertain meaning. It differs from equivocation, which arises from the twofold sense of a single term.

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)

Defn: 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.
