Explanations:Proper nouns are specific names of particular people, places, or things. They are always capitalized in English. In the given sentence, "I live in Delhi but my grandmother lives in Ranchi," the proper nouns are "Delhi" and "Ranchi." These are the names of specific cities in India and are therefore proper nouns.
Let's break down the sentence to understand why the other words are not proper nouns:
"I" is a personal pronoun used to refer to the speaker or writer. It is not a specific name and thus is not a proper noun.
"Grandmother" is a common noun, which refers to a general category of people (a mother's or father's mother). It is not a specific name and is not capitalized unless it is part of a specific name, such as "Grandmother Smith."
"Live" is a verb in this sentence, indicating the action of residing in a place. Verbs are not proper nouns.
Understanding proper nouns is crucial for correct grammar and writing. Proper nouns are always capitalized, and they refer to specific entities, such as names of people, places, or things. In contrast, common nouns refer to general categories and are not capitalized unless they are at the beginning of a sentence or part of a title.
It is important to recognize the difference between proper and common nouns to avoid common mistakes in writing and grammar. For example, "Delhi" is a proper noun because it is the name of a specific city, while "city" is a common noun because it refers to the general category of urban areas.
