Explanation of the author's (may Allah have mercy on him) statement: "… Chapter: Declinable words are of two types: a type that is declined by vowel marks, and a type that is declined by letters …"

The Shaykh : He (may Allah have mercy on him) says: "Chapter" This chapter is a summary of what came before, a summary of what came before. The author (may Allah have mercy on him) has gathered it well, because in the first section he made the positions of division the markers of declension, whereas this section gathers each type separately. That is, he gathered the sound masculine noun alone, the dual alone, and the five nouns alone. This is closer to the student than the previous chapter. He said: "Declinable words are of two types: a type that is declined by vowel marks and a type that is declined by letters" The vowel marks are the fathah, the kasrah, and the dammah. What about sukun? How is sukun a vowel mark? Sukun is static. Well, this is declined by vowel marks. And what is declined by letters is of four types: letters such as alif, ya, waw, and the like. There are four types. This chapter does not go beyond what came before; it merely gathers the issue.
