Emily Dickinson Lexicon

AM-BIG'U-OUS, a. [L. ambiguus.]

Having two or more meanings; doubtful; being of uncertain signification; susceptible of different interpretations; hence, obscure. It is applied to words and expressions; not to a dubious state of mind, though it may be to a person using words of doubtful signification; as, the ancient oracles were ambiguous, as were their answers.
