Title: Interrogative Pronouns Demystified: Definition, Functions, and Instances

Who/Whom

Interrogative pronouns hold an indispensable position within the intricate web of English grammar. The pronoun “who” assumes the role of the focal point, directing our inquiries toward the identity and inherent qualities of an individual. A prime illustration is found in the probing question, “Who is the new student?” In stark contrast, the pronoun “whom” emerges as the target, serving as the recipient of an action or the object thereof. An illustrative instance lies in the query, “To whom did you give the book?” While the disparity between “who” and “whom” may appear nuanced at first glance, it is of paramount importance to utilize “who” when the pronoun assumes the subject position in a clause or sentence and to employ “whom” when it assumes the object position, thus securing linguistic harmony.

The profound disparity between the pronouns “who” and “whom” resides in their grammatical functionalities within a sentence. The pronoun “who” primarily operates as the subject or subject complement, denoting the individual executing the action or being depicted. Conversely, the pronoun “whom” assumes the role of the object of a verb or preposition, signifying the individual on the receiving end of the action or adversely affected by it. To ascertain the correct employment of “who” or “whom,” a comprehensive analysis of sentence structure is imperative. Should the pronouns function as the agent of the action, “who” must be enlisted; conversely, if it assumes the role of the recipient or object of the action, “whom” shall be deemed the apt selection.

What

The interrogative pronoun “what” serves as a linguistic tool that instigates direct or indirect inquiries, extracting precise details or clarification. As an interrogative pronoun, “what” finds utility in probing the essence, identity, or attributes of a subject, object, or occurrence. Moreover, “what” assumes the role of a relative pronoun, ushering in relative clauses to impart supplementary elucidation or to delimit the subject or object within a sentence. Here are some interrogative pronoun examples of how “what” is used in questions:

• What is the capital of France?
• What time does the movie start?
• What is your favorite color?

In a particular context, the utilization of the term “what” arises in the pursuit of acquiring intricate particulars pertaining to the nature, quality, or characteristics of a noun or object. For instance, it can be effectively employed to inquire about descriptive aspects, such as “What color is the sky?” or “What are the main components of a cell?” Moreover, “what” can be employed to elicit  preferences or alternatives in situations, as in “What would you like to have for lunch?” or “What are your career aspirations?” Furthermore, “what” functions as an integral part of indirect questions, offering a tactful means to solicit information while evading overt directness. For instance, “Can you tell me what time the event starts?” or “I wonder what her favorite book is.”

Which

The pronoun “which” frequently initiates relative clauses, forging intricate links between the principal clause and a subordinate clause. “Which” is a relative pronoun that assumes the role of a relative pronoun, thereby augmenting the information about the noun or pronoun it modifies. It is primarily employed in reference to inanimate objects or animals. For example, in the sentence “The book, which is on the shelf, belongs to Sarah,” “which” introduces the relative clause “is on the shelf” and describes the book.

When determining whether to use “which” or “what,” it becomes imperative to meticulously contemplate the contextual milieu and underlying intention of the question. “Which” is used when presenting a limited set of choices or options, implying that the question seeks to differentiate or select from among them. On the other hand, “what” is employed when the question seeks information without any predetermined options or limited choices. It is more open-ended and invites a broader range of responses.

Whose

The pronoun “whose” stands as a possessive pronoun, signifying the notion of possession or ownership. It frequently finds application within the English language to denote the intricate bond between an individual or entity and the possessed object. “Whose” is used when referring to people, animals, or things, and it functions as an interrogative pronoun, introducing a question that seeks information about ownership. For instance, in the sentence “To whom does this book belong?”, “whose” initiates an inquiry concerning the book’s possessor. Similarly, in the sentence “A gratification was granted to the student whose academic performance exhibited enhancement,” “whose” assumes the role of a relative pronoun, tethering the subordinate clause “whose academic performance exhibited enhancement” to the noun “student,” signifying the ownership of the improved academic accomplishments.

“Whose,” functioning as a relative pronoun, serves to initiate subordinate clauses that provide additional information about the possessor or ownership of a preceding noun. An interrogative pronoun example of this usage would be, “The student, whose textbook was misplaced, requested assistance from the teacher.”
