Conversion or transformation of a sentence implies changing grammatical form of a sentence from one to another without changing its meaning. It can be done in a number of ways.
One of the methods is to interchange different types of sentences i.e. Simple Sentence, Compound Sentence and Complex Sentence. Before understanding conversion a brief view about these types of sentences.
A sentence comprises generally of following parts : Subject, Verb and Object. OR Subject and Predicate.
The Simple Sentence
A sentence usually comprises of a subject and a predicate or in other words there is a subject , a verb and an object in a sentence. For example :
- The girl sings a song.
- He is a noble man.
In sentence no. 1 ‘The girl’ is subject and ‘sings a song’ is a predicate. OR
‘The girl’ is subject and ‘sings’ is a verb and ‘a song’ is object.
Similarly is sentence no 2 ‘He’ is a subject and ‘is a noble man’ a predicate.
Such a sentence is called a Simple Sentence.
In other words, a simple sentence has a subject and a predicate.
The Compound Sentence
A compound sentence is sentence made up of two parts joined by a coordinating conjunction. For example :
- The sun rose and the birds started chirping.
- I went to the market and purchased sweets and ate them.
The sentence 1. is formed of two parts –
The sun rose.
The birds started chirping.
Both these parts are joined by conjunction ‘and’.
This is a compound sentence and each part is called a clause. Each part has a sense and its own meaning. Each one can be written independently. It is also called a ‘coordinate clause’.
Similarly sentence 2 is also a compound sentence. It comprises of three coordinating clauses –
I went to the market.
(I) purchased sweets.
(I) ate them.
All these three clauses are joined by conjunctions ‘and’.
These two sentences are called compound sentences.
A compound sentence is formed of two or more coordinate clauses. A compound sentence having two coordinate clauses is called Double Compound sentence whereas a Compound sentence with more than two coordinate clauses is called a Multiple Compound sentence.
The Complex Sentence
A complex sentence consists of two clauses one of which is the Main clause and the other Subordinate clause. Each clause has a Subject and a Predicate. The Principal clause is independent clause whereas Subordinate clause is dependent on the Principal clause and cannot be used as an independent clause. For example :
- It started raining when I reached home.
- When I reached my office, I found that my boss was not there.
In the case of sentence 1, there are two clauses :
- It started raining 2. When I reached home.
First clause is independent part whereas the second clause is dependent on first. The second gives meaning when joined with first. So first is Principal clause and the second is Subordinate clause. Similarly in the sentence 2 there are three clauses –
- I found
- That my boss was not there.
- When I reached my office.
- is an independent clause and is called Principal Clause.
- and 3 are subordinate clauses dependent on 1. Therefore
A complex sentence is a sentence which contains a Main clause or Principal Clause and one or more than one Subordinate clauses dependent on the Main clause for their meaning.
A Subordinate clause is of three types as follows-
- Adverbial Clause
- Adjective Clause
- Noun Clause

II Adjective Clause :
