What refers to a group of words that express a complete thought and contains a subject and a verb?

A group of words that expresses a complete thought and contains both a subject and a verb is known as a sentence. A sentence must convey a complete idea and typically consists of a subject (the person or thing the sentence is about) and a predicate (which includes the verb and tells what the subject does or is). This structural integrity is what distinguishes a sentence from other groupings of words, such as phrases or fragments, which either lack a complete thought or do not contain both subject and verb. A properly constructed sentence can stand alone and provide meaning to the reader.
