Is it correct that some people define the khabar (predicate) as the part that completes the meaning with the mubtada (subject), excluding the mentioned description?

The questioner : Some people say—May Allah reward you—that it is the part that completes the meaning with the mubtada (subject), excluding the mentioned description. Is this correct, O Shaykh?

The Shaykh : But that is not a good definition. It should be said: It is the word or speech that completes the meaning with the mubtada (subject); it is what completes the meaning with the mubtada (subject). That is fine.
