Sentence and Kinds of Sentences

Sentence is the combination of words between two full stops (periods) that conveys full meaning instead of noun or phrase.

Cow is grazing in the field.

If I just say cow it doesn’t give any idea or any meaning that what I mean by saying cow, but when I use it in complete meaningful way, it will be just like above example. Therefore the sentence is complete in meaningfulness.

In another case if we say intelligent boy that will be a phrase with no complete meaning. Similarly “, must keep it clean” too is not completely meaningful. This is the example of Clause. Phrase and Clause will be discussed later.

There is one more definition of sentence that it carries Subject, Object and a main verb. It starts with capital letter and ends on full stop (period), question mark or sign of exclamation.


  1. There are some beautiful flowers in the garden.
  2. What a nice car you have!
  3. What are you doing here?

Subject, Predicate, Object

Sentence is the combination of words with complete meanings as mentioned before. for example; He is playing nicely.
Sentence is made up of two major parts known as Subject and Predicate.

Subject + Predicate = Sentence

Subject is also called actor in a sentence because it is doer which performs action. Main verb of the sentence is related to the subject which is called subject verb agreement. Subject can be either noun or pronoun.


  • Martin jumps over the wall. (Martin is Subject and Noun)
  • He wrote the best essay in the class. (He is subject and Pronoun)

Predicate is the leftover part of the sentence. It means that except subject that whole sentence is called predicate. Predicate indicates something about subject.

He is teaching English in the College.
(Here He is subject and teaching English in the College is Predicate)
There are some other examples below

Subject Predicate
I want a piece of chalk.
They are running a big store.
She is listening to the lecture.

Object is the part of Predicate as is very much clear in the above examples, where chalk, store and lecture are objects and part of Predicate.

Kinds of Sentence

There are four kinds of sentences;

  1. Assertive (Declarative)
  2. Interrogative
  3. Imperative.
  4. Exclamatory

Assertive (Declarative) Sentences
Assertive (Declarative) Sentences are simply statements they are neither negative nor interrogative and end on full stop (period).


  1. He visits me regularly.
  2. She was speaking to the pitch of voice in the class.

Interrogative are those sentences which carry question. They end with Question mark (sign of interrogation).


  1. What are you doing here?
  2. What is your name?
  3. Are you not interested in English?

Those sentences are called imperative which carry command, advice or request. They also end on full stop (period).


  1. Don’t tell a lie ever.
  2. Open your books at page 30.

Exclamatory are those sentences which carry some strong feelings of sorrow, pleasure or wonder. If Interjection (ah, oh, hurrah etc) are used in the beginning then they are followed by the sign of exclamation. Otherwise sign of exclamation is used at the end of a sentence.


  1. How wonderful is this evening!
  2. Oh! We have to go to school to marrow.
  3. Hurrah! We won.
