What term is used to describe something open to more than one interpretation?

The term that best describes something open to more than one interpretation is "ambiguous." When a statement or idea is ambiguous, it means that it can be understood in multiple ways, leading to different interpretations depending on the context or perspective of the reader or listener.

While "equivocal" may also suggest uncertainty or ambiguity, it is often used more specifically in contexts where there are deliberate efforts to be misleading or where the meaning is intentionally unclear. "Vague," on the other hand, refers to a lack of precise detail, which can also lead to ambiguity, but it does not inherently carry the same connotation of multiple interpretations as "ambiguous" does. "Clear-cut" directly contrasts with ambiguity, indicating something that is straightforward and easily understood without room for different interpretations. Thus, the most accurate term for something that can be interpreted in various ways is "ambiguous."
