Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

ambĭfārĭam, adv., v. the foll. fin.

ambĭ-fārĭus, a, um, adj. [cf. the Gr. δι-φάσιος, τρι-φάσιος, and v. aliquot-fariam], that has two sides, of double meaning, ambiguous (only post-class.): fabulae, Arn. p. 181: obtentio, id. p. 182.
Hence,

    1. 1. * ambĭfārĭē, adv., ambiguously, Mamert. Stat. Anim. 1, 3.
    2. 2. ambĭfārĭ-am, adv. (orig. acc. fem. sc. partem), on two sides, in two ways, ambiguously, = in utramque partem, App. Flor. 4, 18, p. 360, 25; so id. Mag. p. 276, 2.
