The compound sentence is a composite sentence built on the principle of coordination. Coordination, the same as subordination, can be expressed either syndetically (by means of coordinative connectors) or asyndetically.
The main semantic relations between the clauses connected coordinatively are copulative, adversative, disjunctive, causal, consequential, resultative.
Similar semantic types of relations are to be found between independent, separate sentences form-ing a continual text. As is known, this fact has given cause to some scholars to deny the existence of the compound sentence as a special, regular form of the composite sentence.
Compound sentences consist of clauses joined together by coordinating conjunctions: and, but, or, for, yet.
The problem of communication types:
There are compound sentences consisting of clauses belonging to different communication types. In this case it is impossible to state to what type the compound sentence as a whole belongs.
e.g. These came nearer than most to meaning something to her, but what? (declarative + interrogative).
-> Can we call a compound sentence a sentence at all? According to communication type – NO
There is theory on the unity of communication type, which recognizes compound sentences as a special sentence type.
