Quick answer

Having more than one possible meaning, so it isn't clear which one is intended.

Ambiguous describes words, sentences, or situations that can be understood in more than one way, so the meaning is not clear. "I saw her duck" is ambiguous, because duck could be a bird or a movement. Ambiguous answers leave people unsure, and an ambiguous result is hard to judge. It is different from vague, which means lacking detail altogether.

"His ambiguous answer left everyone unsure whether he had actually agreed."
