And what is the difference between coordinating and subordinating conjunctions? Is one kind of sentence (compound or complex) characterized by either a coordinating or subordinating conjunction, while the other kind is characterized by the other?

  • This might be a good place to ask, but I'm having trouble understanding what you are asking. Do you think you can make your question clearer?

  • @KitFox: Are coordinating/subordinating conjunctions used in compound/complex sentences or clauses? Do I have my terms "backward?" Examples? Sorry for the "matrix" format of this question but I think in those terms.

Yes, this is a good place. It's simple, really.

There are two ways to combine clauses. One of them is simply stacking together sentences, like

  • He went to the store and he bought some bread and he drove home but he left it in the car.

This is a compound sentence (not "compound clause", by the way); it contains only clauses that are linked together by the coordinating conjunctions and, or, and but. Compound sentences can be reduced by Conjunction Reduction, producing, for instance

  • He went to the store and bought some bread and drove home but left it in the car.

Compound sentences are easy; all the sentences are on the same level as main clauses, and none of them modify another clause.

Complex sentences — the other way to combine clauses — are not easy. A complex sentence has at least one subordinate clause, and there are a lot of different kinds of subordinate clause, each with their own set of rules and their own set of idioms and connotations.

    OK, it seems like my basic idea was right. "Coordinate" =compound, "subordinate = complex, and those are the ways you make sentences out of clauses. The examples were helpful. +1 possibly an acceptance, but I like to wait a day or two for the latter.

  • Yeah, pretty much. But the names are irrelevant, really. Most sentences are complex sentences, and that's what syntax is mostly about. Apr 12 '13 at 15:29

COMPOUND SENTENCES:- Having one or more main clauses.

SIMPLE SENTENCES:- Having a main clause.

COMPLEX SENTENCES:- Having one main and two or three subordinate clauses.
