The common criterion across the predicate’s rhetorical states is appropriateness to context (muqtaḍā al-ḥāl). Two expressions may share the same broad truth-conditions while communicating it differently.
FormTypical rhetorical effect
OmissionAvoids repeating a recoverable predicate
ExpressionCompletes, clarifies or reinforces the claim
Verbal predicateForegrounds event, tense or renewal
Nominal predicatePresents a state or description
Qualification/conditionRestricts the action or its realization
PreposingHighlights focus, restriction or praise
These are interpretive tendencies, not unconditional rules. The source must always be read alongside its cues, addressee, and intended communicative purpose.
