* Ambiguous: This is the most common and general term. It means that the sentence could be interpreted in more than one way.
* Polysemous: This refers to a word with multiple meanings, which can lead to sentence ambiguity.
* Equivocal: This term is similar to ambiguous but emphasizes that the multiple meanings are distinct and potentially conflicting.
* Double entendre: This refers specifically to a sentence with a humorous or suggestive double meaning.
The best term to use depends on the specific context and the nature of the ambiguity.
