A Complex Sentence has a dependent and an independent clause.
Ex: After i came home, I ate dinner.
Dependent clauses are not complete and can not be used by themselves. Dependent clauses need to be connected with an independent clause. Ex: After I came home
Independent clauses are complete by themselves. They don't need another part to be complete. However, they can be connected with a dependent clause to make the dependent clause complete. Ex: I ate dinner.
Which is an independent clause/ complete sentence?
