How many parts does a complete sentence have?

A complete sentence typically has two essential parts: a subject and a predicate. The subject is the part of the sentence that tells us who or what the sentence is about, and the predicate provides information about the subject, which usually includes a verb and may also include additional details.

For example, in the sentence "The dog barks," "The dog" is the subject, and "barks" is the predicate. Together, they form a complete thought, making the sentence grammatically complete. Without either of these two components, you would not have a complete sentence; instead, you might have a fragment or an incomplete thought. Thus, two parts, the subject and predicate, are necessary to construct a complete sentence.
