Explanation of Ibn Malik’s (may Allah have mercy on him) statement: “Speech and what is composed of it.”

The Shaykh :“Speech and what is composed of it” This is a title, and its original form is “This is the chapter on speech and what is composed of it.” In it, two elements are omitted:
The first omitted element is the subject (mubtada').
The second is the predicate (khabar), which is the possessed noun. It was omitted, and the noun it was attached to was placed in its stead, so “speech and what is composed of it” means: what speech is gathered from.
