In Al-Sabbans footnote to Al-Ashmounis commentary on Ibn Maliks Alfiyyat, there is something that gives the impression that it is similar, either in ruling, or in connotation, or in parsing, or otherwise. So Al-Sabban intends to point out that difference, taking advantage of what he has provided from the books of grammarians, so he explains it in a concise phrase that suits the situation, relying on the culture of the reader. Grammatical understanding in order not to talk about it for too long, making the book heavy and moving away from the topic that the commentator is about to explain. In this research, I counted these differences and then discussed examples of them with useful analysis, clarification, and clarification from the books of grammarians, both ancient and late, in an easy phrase that suits the language of the era.
