No, the word ‘she’ is not a common noun; it is a pronoun.
Explanation: A common noun refers to a general name for a person, place, or thing, such as ‘apple’, ‘city’, or ‘woman’. In contrast, ‘she’ is a personal pronoun used to refer specifically to a female individual. Pronouns function differently from nouns as they replace nouns in sentences, making communication more fluid and avoiding repetition. Therefore, while ‘she’ may denote a person, it categorizes as a pronoun rather than a common noun.
