Emphasizing Clarity:
* Precisely vague: This highlights the paradox of being both clear and unclear at the same time.
* Specifically ambiguous: This emphasizes the intentionality of being vague while still aiming for a specific effect.
* Clearly indefinite: This emphasizes the unexpected clarity of a seemingly unclear statement.
Emphasizing Uncertainty:
* Definite uncertainty: This highlights the unexpected certainty within a state of uncertainty.
* Certain ambiguity: This emphasizes the unusual confidence in something ambiguous.
* Concrete vagueness: This emphasizes the solidity of something that is essentially undefined.
The best choice will depend on the specific context and the effect you want to achieve.
