AMBIGUOUS most nearly means:

AMBIGUOUS means having more than one possible meaning; unclear or confusing. Example: 'His ambiguous answer left everyone wondering what he meant.' From Latin 'ambi-' (both) + 'agere' (to drive) — going both ways. Synonyms: unclear, vague, indefinite, equivocal, dubious, cryptic. Antonyms: clear, unambiguous, definite, certain, explicit. Related: AMBIGUITY (noun — the quality of being ambiguous); the 'ambi-' prefix appears in: AMBIDEXTROUS (skilled with both hands), AMBIVALENT (having mixed feelings — both wanting and not wanting), AMBIENT (existing on all sides, surrounding). Words about clarity/unclarity: AMBIGUOUS (multiple meanings), VAGUE (lacking detail), CRYPTIC (deliberately mysterious), OBSCURE (not well-known or unclear), OPAQUE (not transparent or hard to understand), LUCID (clear and easy to understand), TRANSPARENT (easy to see through, clear). The ASVAB tests these subtle differences in meaning.
