How to Ensure You Write in Complete Sentences

Correct sentence structure is one of the most important aspects of grammar. A sentence is a group of words that make sense. Your sentences can be either complete or incomplete. A complete sentence needs essentially only two things – a subject and a verb that is conjugated to match the subject. Sentences can be simple, compound, or complex. They can have independent and dependent clauses. An independent clause is a group of words that can stand on its own as a complete sentence because it expresses a complete thought and makes sense as it is. Incomplete sentences can be of two types: fragments and run-on sentences. Let us give you examples of both so that you can understand how to avoid them. Example of a complete sentence: Sarah, who was a competent chef skilled in making pizzas and pasta, has opened her own Italian restaurant. Example of a fragment: Sarah, who was a competent chef skilled in making pizzas and pasta. Example of a run-on sentence: Sarah was a competent chef she opened her own Italian restaurant.
