Which type of sentence specifically features one clause with a subject and predicate?

A simple sentence is characterized by having one independent clause that contains a subject and a predicate. This structure allows it to express a complete thought without the need for additional clauses. For example, the sentence "The dog barks" is a simple sentence that has the subject "the dog" and the predicate "barks," fulfilling the definition perfectly.

In contrast, a compound sentence consists of two or more independent clauses typically joined by a conjunction, which means it has more complexity than just a single clause. A complex sentence contains at least one independent clause and one or more dependent clauses, adding even more complexity by introducing subordinating relationships between ideas. A persuasive sentence, while not a formal category of sentence structure, typically aims to convince the reader and can take various forms. However, it does not have a specific structural definition related solely to clauses as the simple sentence does.
