What are the 5 parts of a complete sentence?

There are not exactly "5 parts" of a complete sentence, but rather 5 elements that are essential for a sentence to be grammatically correct and convey a complete thought. These elements are:

1. Subject: The person, place, thing, or idea that the sentence is about.

2. Verb: The action the subject is performing or the state of being of the subject.

3. Object: The person, place, thing, or idea that receives the action of the verb. (Not all sentences have an object.)

4. Complement: A word or phrase that provides more information about the subject or object. (Not all sentences have a complement.)

5. Modifiers: Words or phrases that describe or modify other words in the sentence. (Not all sentences have modifiers.)

Here's an example:

* Subject: The cat

* Verb: sat

* Object: on the mat

* Complement: (none)

* Modifier: The fluffy, white cat

Complete sentence: The fluffy, white cat sat on the mat.

Note: While all five elements are important for a sentence to be grammatically correct, not all sentences will include all five elements.
