Grammar topic pronoun

A pronoun is a word that is used in place of a noun and does the work of a noun,
e.g: Ram is a boy. Ram reads in class seventh. Ram is a good athelete.
Ram works hard. Ram obeys his parents. Ram is an ideal student.
Here, A boy Ram has been described and a few of his qualities have been said. But, the repeated use of a noun lets the beauty of writing fade away and hence we need to replace the noun by a pronoun. When we use pronoun in place of the noun then it preserves the beauty of writing.
Ram is a boy. He reads in class seventh. He is a good athelete. He works hard. He obeys his parents. He is an ideal student.
Now, as the pronoun ‘He’ has replaced the noun ‘Ram’ the sentences are very much pleasing to read. Pronoun saves the noun from getting repeated and also beautifies the sentence.
