As its name suggests, this type of sentence combines the features of compound and complex sentences:
The compound-complex sentence allows for an endless variety of sentence patterns, from very basic to highly complex.
The most basic pattern has two independent clauses (IC + IC), together with one dependent clause (DC), which can be attached at the beginning, middle or end. Here are some examples from Canadian authors, with the dependent clauses in italics.
DC at the beginning: DC + IC + IC
DC in the middle: IC + DC + IC
DC at the end: IC + IC + DC
A compound-complex sentence very often contains more than three clauses. Here is just one example of a longer sentence, containing five clauses:
2 ICs with 3 DCs: IC + DC + DC + DC + IC
