These sentences contain two or more independent clauses. Normally, these clauses are joined by a coordinating conjunction such as for, and, nor, but, or, yet, so. Compound sentences are meant to give extra detail and information.
Eg. The boys went to the park, but they did not go to the zoo.
Complex sentences
A complex sentence contains two different clauses. In most cases, there is an independent clause as well as a dependent clause joined together by a subordinating conjunction such as after, before, although, since, because, since, if, unless, whenever, even though, so that. Complex sentences also aim to provide extra detail and information.
