vague

This term describes a lack of precision that often creates a sense of frustration or uncertainty. It suggests a blurriness in communication or thought, where the boundaries of a concept are fuzzy rather than sharp. It is frequently used in professional or legal contexts to criticize a lack of specificity in a contract or a directive.

While similar to ambiguous, which implies multiple possible meanings, vague refers to a general absence of detail. A vague answer provides almost no information, whereas an ambiguous answer provides information that could be interpreted in two different ways.
