π What is a Complete Sentence?
A complete sentence is a group of words that expresses a complete thought. It has a subject (who or what the sentence is about) and a predicate (what the subject does or is). It also starts with a capital letter and ends with a punctuation mark like a period (.), question mark (?), or exclamation point (!).
- πββοΈ Subject: Who or what the sentence is about.
- verb πββοΈ Predicate: What the subject does or is.
- βοΈ Complete Thought: Makes sense on its own.
π What is an Incomplete Sentence (Fragment)?
An incomplete sentence, also called a sentence fragment, is missing a subject, a predicate, or both. It does not express a complete thought and leaves you wanting more information.
- π Missing Subject: Doesn't tell who or what.
- π§ Missing Predicate: Doesn't tell what the subject does or is.
- β Incomplete Thought: Doesn't make sense on its own.
