20. Compound-Complex sentence.

Explanation:

A sentence can be defined as a group of words that comprises of both a subject and predicate used to convey a logical information. Sentences are classified into four (4) main categories and these includes;

I. Simple sentence.

II. Compound sentence.

III. Complex sentence.

IV. Compound-Complex sentence.

In English language, a simple sentence can be defined as a sentence that comprises of a single independent clause, a predicate or verb and a subject. Also, the subject in a simple sentence is joined together by a conjunction such as "and" to reflect the action that is being performed or done by the verb in the sentence.

On the other hand, a compound-complex sentence comprises of a minimum of two independent clause and at least a dependent clause. Therefore, a compound-complex sentence has at least two subordinate clause and as such it is a combination of complex and compound sentence with a conjunction.

"Halley's comet should return in the year 2061." is an example of a simple sentence.

"When I arrived at the office, I found that the principal was out; apparently, he had contracted the same sickness as half the school." is an example of a compound-complex sentence.
