Topic: Pronoun (সর্বনাম),

Best Answer Explained in Below-:

In the sentence "Everybody hates a liar," the word "everybody" functions as a pronoun. More specifically, it is an indefinite pronoun, which refers to a non-specific group of people, encompassing all individuals within that group. Pronouns are words that replace nouns in sentences, serving to avoid repetition and streamline communication.

In this context, "everybody" conveys the idea that all people, without exception, share a common sentiment towards liars. This broad categorization emphasizes the universal nature of the sentiment expressed. Other options in the list, such as "noun," "adjective," or "adverb," do not accurately describe "everybody." While “liar” is a noun referring to a person who lies, “everybody” does not name a specific person or thing but instead represents a collective group.

Understanding the role of "everybody" as a pronoun highlights the importance of indefiniteness in language, allowing speakers to convey inclusivity and generalization effectively. This distinction is crucial in grammar, as it defines how we categorize words based on their function within sentences.
