The term "ambiguous" refers to something that is not clear or has more than one meaning. This could apply to words, sentences, situations, or any context where a single interpretation might not be obvious. For example:
An ambiguous word might have multiple meanings, such as "bank" which could refer to a financial institution or the side of a river.
An ambiguous sentence might leave room for interpretation, such as "I think he said he was coming" which doesn't clearly state if the person was coming or not.
An ambiguous situation might lack sufficient information for a clear decision, such as a friend's non-committal response to a dinner invitation.
Ambiguity is often intentional, as in legal contracts or advertising, where it may be designed to be open to interpretation, but it can also be unintentional and lead to misunderstandings.
