I can differentiate between simple, compound, and complex sentences and construct my own examples of each.

1
A simple sentence contains one independent clause, meaning it expresses a complete thought with a subject and a verb.
2
A compound sentence combines two or more independent clauses, often joined by a coordinating conjunction or a semicolon.
3
A complex sentence includes one independent clause and one or more dependent clauses, which often begin with subordinating conjunctions or relative pronouns.
