Sentences - Kind of It

Three kinds of sentences and they are:
a)The simple
b)The complex, and
c)The compound sentence

a. Study the following sentence.

He wrote a letter.

The sentence given above has only one clause. A sentence having only one clause is called a simple sentence.

b.The complex
This complex sentence consists of two clauses ‘He wrote a letter’ and ‘while she watched TV’. Here the clause ‘He wrote a letter’ makes complete sense and can stand independently. It is, therefore, a main clause. Now consider the clause ‘while she watched TV’. This clause, too, has a subject and a predicate of its own, but it doesn’t make complete sense. It is, therefore, a subordinate clause. A sentence having one main clause and one or more subordinating clauses is called a complex sentence.

c.The compound sentence
The compound sentence given above consists of two clauses ‘He wrote a letter’ and ‘she posted it.’ Both of these clauses make complete sense and can stand independently. Both clauses are therefore main clauses.
