A sentence that consists of just one clause, i.e. one that has just one nite verb, contains simply a main clause. A sentence that has more than one clause, i.e. one that has more than one nite verb, is a compound or complex sentence as it consists of more than simply a main clause; the additional clause or clauses must by necessity be either coordinate or subordinate clauses, which means they are joined to the main clause by means of either a coordinating or a subordinating conjunction. These conjunctions or joining words have important rami cations for word order in German and they are the topic of this chapter.
