What is the difference between a simple, compound, and complex sentence? Provide examples.

A simple sentence is a sentence that consists of only one independent clause, which means it expresses a complete thought on its own. It contains a subject and a predicate, and it does not have any dependent clauses or conjunctions. Here is an example of a simple sentence: "She walked to the park."

A compound sentence is a sentence that consists of two or more independent clauses joined together by coordinating conjunctions (such as "and," "but," "or," "so," etc.) or semicolons. Each independent clause in a compound sentence can stand alone as a separate sentence. Here is an example of a compound sentence: "She walked to the park, and he rode his bike."

A complex sentence is a sentence that consists of one independent clause and at least one dependent clause. A dependent clause cannot stand alone as a complete sentence because it relies on the independent clause for its meaning. Complex sentences are formed by using subordinating conjunctions (such as "although," "because," "since," "while," etc.) to connect the dependent clause to the independent clause. Here is an example of a complex sentence: "Although she walked to the park, she got tired."

In summary, the main difference between a simple, compound, and complex sentence lies in the number of independent clauses and the presence of dependent clauses. A simple sentence has one independent clause, a compound sentence has two or more independent clauses, and a complex sentence has one independent clause and at least one dependent clause.
