Simple, compound or complex sentence?

A simple sentence consists of just one clause. A compound sentence consists of two main clauses of equal weight joined by a conjunction. A complex sentence is made up of a main clause and one or more subordinate clauses. Conjunctions such as because, although, until are usually used to link the subordinate clauses to the main clause.
