هُوَ شُجَاعٌ وَلَكِنَّهُ لَا يَتَهَوَّرُ.
He is courageous, but he is not reckless.
If 'courageous' could be misconstrued as 'rash', the qualifying clause prevents a plausible mistaken inference. This is iḥtirās, protective qualification. Its defining rationale is the danger of misunderstanding, not merely the elegance of adding an extra favorable description.
In a setting where recklessness was never a live implication, the same addition may instead provide supplementary praise or useful detail. The wording has not changed; the communicative circumstance has, and that can alter the rhetorical classification.
