The accompanying discussion appeals to sound linguistic taste (al-dhawq al-sahih). This means an informed feeling for the language, not simply one reader's private preference.

A proper analysis identifies the nature of the articulatory difficulty and distinguishes sound combinations within one word from clashes occurring across a phrase.
