Yes.
Every sentence has a subject, what the sentence is about, and a predicate, what tells something about the subject. In this sentence, the subject is "cat" and the predicate is "content."
The predicate part of the sentence tells what the subject does or has. It can also describe what the subject is or is like.
The simple predicate is the main verb in the predicate that tells what the subject does.
The predicate is the part of the sentence that tells what the subject is or does. It typically includes the verb and any additional information about the subject's action or state.
Every complete sentence has two parts, a subject and a predicate. The subject is the part of the sentence that tells who the sentence is about and the predicate tells what the subject is doing.
An active verb is required; any other part of speech may be present.
The complete predicate of a sentence is the predicate verb with all its modifiers. A simple predicate is an action word that tells something about the subject.
The predicate tells what the subject does.example: Mr. Morton blushes. Mr. Morton is the subject .The predicate is blushes because this is the what Mr. Morton does.
"Was Herbert cleaning" is a complete sentence with "Herbert" as the subject and "cleaning" as the predicate. The subject is the person or thing the sentence is about, and the predicate tells us what the subject is doing.
it tells what the subject is doing
A complete sentence is comprised of a subject and a predicate. The subject is a noun or noun phrase, and the predicate essentially tells what the subject does.
The simple predicate is "is," as it tells what the subject "cockroach" is.
