Simple, Compound, and Complex Sentences
There are three basic sentences types. They get their names from their structures. The structures can be either simple, joined as equals, or joined with a subordinate. I’ll explain.
What is a simple sentence?
A simple sentence has a subject and a verb and sometimes an object or complement. The subject is who or what the sentence is about. The verb and the object or complement together are often called the predicate. A simple sentence has two parts: its subject and its predicate.
She smiled. (subject + verb)
She looked pretty. (subject + verb + complement)Simple sentence
What is a compound sentence?
A compound sentence has two or more simple sentences joined together, usually with a comma and a coordinating conjunction.
She smiled, and she laughed. (Two sentences joined with a comma + coordinator.)Compound sentence.
What is a complex sentence?
A complex sentence is a simple sentence with subordinate clause joined to it. A subordinate clause depends on another clause to complete an idea, so we call subordinate clauses dependent clauses.
She smiles when she is happy. (Independent clause + dependent clause)Complex sentence
