Khaṣm means an adversary or disputant and can occur with an unusually broad range of number or gender in classical usage. Alwā intensifies the idea of argumentative stubbornness. Naṣīḥ presents a counselor ostensibly offering good advice, but here the counsel takes the form of reproach against the affair.
Taʿdhāl means repeated or forceful blame. Muʾtalin can imply withholding or falling short of an effort; consequently, ghayri muʾtali means not holding back from reproach.
The movement khaṣm → naṣīḥ → taʿdhāl describes a single figure through opposition, claimed concern, and tireless criticism. The vocabulary concentrates the psychological pressure against which the speaker asserts himself.
