A compound sentence is a sentence which consists of two or more clauses coordinated with each other.
We distinguish the following types of coordination:
1) Copulative coordination, expressed by the conjunctions and, nor, neither…nor, not only…but. With the help of these conjunctions the statement expressed in one clause is simply added to that expressed in another.
2) Disjunctive coordination, expressed by the conjunctions or, else, or else, either … or , and the conjunctive adverb otherwise. By these a choice is offered between the statements expressed in two clauses.
3) Adversative coordination, expressed by the conjunctions but, while, whereas, and the conjunctive adverbs nevertheless, still, yet. These are conjunctions and adverbs connecting two clauses contrasting in meaning.
4) Causative-consecutive coordination, expressed by the conjunctions for, so and the conjunctive adverbs therefore, accordingly, consequently, hence.
