1. Subject: The person, place, thing, or idea that the sentence is about.
2. Verb: The action or state of being that the subject performs or experiences.
Here's how it works:
* Incomplete Sentence: "Running down the street."
* This lacks a subject. Who is running?
* Complete Sentence: "The dog is running down the street."
* Now we have a subject (dog) and a verb (is running).
Here are some other factors that can make a sentence incomplete:
* Missing a predicate: The predicate includes the verb and any objects, complements, or modifiers that complete the thought about the subject.
* Incomplete: "The cat..."
* Complete: "The cat chased the mouse."
* Missing a subject: The subject is the noun or pronoun that performs the action or is in a particular state of being.
* Incomplete: "...jumped over the fence."
* Complete: "The rabbit jumped over the fence."
Remember: A complete sentence expresses a complete thought and can stand alone.
