What are the 5 things a sentence needs to be complete?

A complete sentence needs a subject, which indicates who or what the sentence is about. It requires a predicate, typically containing a verb that expresses the action or state of being. The sentence should convey a complete thought, meaning it should make sense on its own and not leave the reader hanging. Additionally, it should have proper punctuation, usually ending with a period, question mark, or exclamation mark.
