Syn:questionable, arguable, debatable, controversial, contentious; informal iffyAnt:sound••doubtful, ambiguous, dubious, enigmatic, equivocal, problematic, questionableIf you are doubtful about the outcome of a situation, you might be understandably dubious about getting involved in it. While all of these adjectives express suspicion, indecision, or a lack of clarity, doubtful carries such strong connotations of uncertainty that the thing being described is as good as worthless, unsound, invalid, unlikely, or doomed to fail (it was doubtful that the plane could land safely). Dubious is not quite as strong, suggesting suspicion, mistrust, or hesitation (a dubious reputation). It can also mean inclined to doubt or full of hesitation. If you're doubtful about the outcome of a particular situation, it means that you are fairly certain it will not turn out well. If you're dubious, on the other hand, it means that you're wavering or hesitating in your opinion. Questionable may merely imply the existence of doubt (a questionable excuse), but like dubious, it also has connotations of dishonesty and immorality (a place where questionable activities were going on). Problematic, in contrast to both dubious and questionable, is free from any suggestion of moral judgment or suspicion. It is applied to things that are genuinely uncertain, and to outcomes that are as likely to be positive as negative (getting everyone in the family to agree could be problematic). Ambiguous and equivocal refer to lack of clarity. But while ambiguous can refer to either an intentional or unintentional lack of clarity (her ambiguous replies to our questions), equivocal suggests an intentional wish to remain unclear (his equivocal responses indicated that he wasn't keen to cooperate). It can also mean capable of different interpretations (an equivocal statement that could be taken to mean opposite things). Something that is enigmatic is likely to be intentionally unclear as well (an enigmatic statement designed to provoke controversy), although enigmatic can also mean perplexing or mysterious.
