Pronouns are words utilised in place of nouns. They can only be used once the noun is used or mentioned. Pronouns are of several types, such as personal, reflexive, emphasising, relative, demonstrative, indefinite, interrogative, and possessive. When personal pronouns are used as the object of the verb, the pronoun is in the objective case, and when they are used as the subject of the verb, they are in the nominative case. When personal pronouns indicate ownership or possession, they are in the possessive case.
