Hi,
I was able to find out something in order to help you. I’m not a native speaker, but I think we could hunt down your question together. May be somebody help us later.
According to the Webster’s grammar guide:
A simple sentence consists of one and only one independent clause ( a group of words that has a subject and a predicate). And an independent clause does not depend upon anything else for its meaning. It expresses a complete thought. But some sentence have compound subject or predicate).
For example: John joined the Navy. (simple subject and predicate). John and Fred joined the Marines. (compound subject). Mary sang and played at the concert. (compound predicate). Mary and Jane sang and played at the concert. (compound subject and predicate). Yet a compound subject does not mean two subjects. It means the one subject is made up of two or more nouns or pronous. And compoud predicate is made up of two preditaces.
A compound sentence is a sentence that contains two or more independent clauses. When you put two independent clauses or two simple sentences together to form longer sentence, you have a compound sentence.
The independent clauses of a compound sentence may be connected in one of three ways:
By using a conjunction, a semicolon without conjunction, a transitional word( yet, at last, still, in fact etc.)
A complex sentence is a sentence that consists of one independent clause and one or more subordinate clauses. A subordinate clause depends upon the independent clause for its meaning.
In the complex sentence is often used a subordinate conjunction. It is used to show that the clause which it introduces is a subordinate clause, and not a main clause. (We listened to the radio because we wanted to hear the news.)
