Right below the video it is stated "a predicate always starts with a verb". However isn't this not necessarily correct? For some sentences, such as an inverted sentence wherein the predicate is stated before the subject, the verb is not first.

For instance "on the table sat the cat".

Predicate: on the table (preposition) sat (verb)

Subject: the cat

So for an example like this wouldn't the statement "a predicate always starts with a verb" be incorrect?
