What does the word "ambiguous" mean?

The term "ambiguous" refers to something that can be understood or interpreted in multiple ways, making it unclear or uncertain. This is particularly relevant in contexts like language, where a statement or phrase might have several meanings depending on how it is interpreted. For example, if someone says, "I saw the man with the telescope," it could be understood in different ways—either that the person saw a man who possesses a telescope or that the observation was made using a telescope. This inherent uncertainty is what characterizes something as ambiguous.

The other options denote clarity, confusion, or limitation, which contrast with the nature of ambiguity. An ambiguous statement lacks a single, clear interpretation, thus aligning perfectly with the definition provided in the correct answer.
