What is a compound sentence?
A compound sentence is a sentence that uses two or more independent clauses, oftentimes being connected with a conjunction. These terms are usually preceded with a comma. Compound sentences can be used to liven up writing that might be dominated with a series of simple sentences. Sometimes, proper use of compound sentences can also vary up writing with its combination of sentences. An example of a compound sentence could be "Roy spent more time with his friends, and Pam went to the store on her own." In this sentence, two simple sentences are combined in the compound format with a conjunction.
A compound sentence is a sentence that has more than one main clause. A main clause has both a subject and a verb, but is not introduced by a subordinating word (like when, for example).
So an example of a compound sentence would be
"The wind blew, and the leaves fell."
But "The leaves fell when the wind blew" would not be a compound sentence because "when" is a subordinating word and that means that "when the wind blew" is not a main clause. Therefore, that sentence does not have two main clauses.
A compound sentence is composed of at least two independent clauses. It does not require a dependent clause. The clauses are joined by a coordinating conjunction (with or without a comma), a correlative conjunction (with or without a comma), or a semicolon that functions as a conjunction. A conjunction can be used to make a compound sentence. The use of a comma to separate two short independent clauses in a sentence is accepted.
