Structure of Sentences

Simple Sentence

A simple sentence, also called an independent clause, contains a subject and a verb, and it expresses a complete thought. Thus, a Simple sentence is one which has only one Subject and one Predicate.


  • The children were laughing.
  • Sachin wanted a new bicycle.
  • He was better than me.

Compound Sentence

A compound sentence contains two independent clauses joined by a coordinator. The coordinators are: for, and, nor, but, or, yet, so (FANBOYS). Except for very short sentences, coordinators are always preceded by a comma.

Thus, a compound sentence is one made up of two or more Principal or Main Clauses.


  • We looked everywhere but we could not find him.
  • They are coming by car so they should be here soon.

Complex Sentence

A complex sentence has an independent clause joined by one or more dependent clauses. A complex sentence always has a subordinating conjunction such as because, since, after, although, when, etc. or a relative pronoun such as that, who, or which.

Thus, a Complex sentence consists of one Main Clause and one or more Subordinate Clauses.


  • Her father died when she was very young.
  • She had a difficult childhood because her father died when she was very young.

  1. when - कब
  2. what - क्या
  3. where- कहा पे
  4. why - क्यूं
  5. who - कौन
  6. whom - किसको
  7. whose - किसका
  8. which - कौन कौन से
  9. how - किस तरह


  • What does she like to drink?
  • When did he go for shopping?
  • Why do you disturb me?
  • Where will you meet Anita?
  • How did you spend your holidays?
  • Whom do they want to select?

Imperative Sentences

Imperative sentences are used for giving instructions. In an imperative sentence, the verb comes before the subject. The sentences that begin with "Don’t" or "Never" and are called Negative Imperative Sentences.
