Among the eight different parts of speech is an important category known as the pronoun. As the name suggests, it has something to do with nouns. A pronoun is a word used to replace a noun. The main purpose of the pronoun is to replace the noun and hence avoid repetitive use of a long lettered noun. For instance, let us say a person’s name is Vaidyanathapura. Imagine a paragraph where Vaidyanathapura is used in five sentences. Instead of using the name five times we can use the name once in the first sentence and replace with a pronoun such as HIM, HE or HIS depending upon the context in which the name is used in the remaining four sentences.
To illustrate with a simple example, look at these two sentences:
‘Vaidyanathapura lived in a small village in India and Vaidyanathapura was a smart boy.’
‘Vaidyanathapura lived in a small village in India and HE was a smart boy.’
