لَيْتَ / هَلْ / لَوْ / هَلَّا
Wishing, questioning as a wish, conditional wishing, and exhortation.
Identify the speaker’s actual intent rather than mechanically classifying a particle by its default use. Whether the desired outcome is possible, whether the verb concerns the past or future, and the addressee’s circumstances together determine the rhetorical force.
