Mistake: every accusative must be a direct object. Correct: some emphasize the action.
Mistake: jalasātin must be genitive because of kasra. Correct: the sound feminine plural uses kasra for the accusative too.
Mistake: all maṣdars are absolute objects. Correct: a maṣdar may be a nominative mubtadaʾ.
Mistake: a verb may always be dropped. Correct: ellipsis needs context or attested idiomatic use.
