Explanation of Ibn Malik’s (may Allah have mercy on him) statement: “And the noun is of two types: inflected and uninflected *** for its resemblance to the letters of the city.”

The Shaykh : He said: “And the noun is of two types: inflected and uninflected”. Of it, some is inflected; the subject is “of it,” and the predicate is “inflected.” The subject is inflected, and the predicate is also inflected. The waw is a conjunction, and “uninflected” is [a separate clause]. Ah.
The student: ... .

The Shaykh : [There is no] uninflected [subject]; its predicate is omitted, and the implied meaning is “and of it, some is uninflected.” Because if you said “of it, some is inflected and uninflected,” you would have combined two opposites. However, the reality is that some of it is inflected and some is uninflected. A parallel to this expression is the saying of Allah the Exalted: It is not correct to say that “Said” is conjoined to “unfortunate.”
