Clear is the most general opposite of vague when information is easy to understand.

Definite
Definite conveys a fixed or certain meaning, decision, or boundary rather than an indistinct one.

Example: The policy is explicit that expenses must be approved in advance.
Unambiguous
Unambiguous means capable of only one reasonable interpretation.

Distinct
Distinct is useful when vague means blurred, faint, or insufficiently differentiated.

Concrete
Concrete replaces vagueness with tangible details, examples, or actions.
Example: The manager turned a vague ambition into three concrete targets.
Exact
Exact stresses complete precision in facts, figures, wording, or location.
Example: Please give the exact address rather than saying the office is near the station.
Detailed
Detailed is appropriate when vagueness results from missing information.

Unequivocal
Unequivocal is a strong formal choice meaning clear and leaving no doubt.
Example: The regulator gave an unequivocal warning that the practice must stop.
