Those Who vs. Those Whom: The Correct Usage Explained with Examples

Navigating the intricacies of English grammar can often feel like traversing a minefield, with subtle distinctions between seemingly similar words leading to common errors. Among the most frequently confused pairs are “who” and “whom,” particularly when they appear in the plural form as “those who” and “those whom.” While modern spoken English sometimes blurs these lines, understanding the correct usage is crucial for clear, precise, and formal writing. This distinction hinges on the grammatical case of the pronoun: whether it functions as a subject or an object within a sentence.

The difference between “those who” and “those whom” is fundamentally about their role in a sentence. “Who” is a subjective pronoun, meaning it acts as the subject of a verb. Conversely, “whom” is an objective pronoun, functioning as the object of a verb or a preposition. Mastering this rule will unlock a new level of grammatical confidence.

Understanding Subject vs. Object Pronouns

At its core, the distinction between “who” and “whom” mirrors the difference between “he” and “him,” or “she” and “her.” These pairs represent the subjective and objective cases, respectively. When a pronoun performs the action of the verb, it is in the subjective case (like “he” or “she”).

When a pronoun receives the action of the verb or is the object of a preposition, it is in the objective case (like “him” or “her”). This fundamental grammatical principle is the key to unlocking the correct usage of “who” and “whom.” It’s not about formality alone, but about grammatical function.

Think of it this way: if you can replace the pronoun with “he” or “she,” you should use “who.” If you can replace it with “him” or “her,” then “whom” is the correct choice.

The “He/Him” or “She/Her” Substitution Test

This simple substitution trick is the most effective way to determine whether to use “who” or “whom.” It requires isolating the clause in which the pronoun appears.

First, identify the clause containing “who” or “whom.” Then, rephrase that clause as a simple statement, substituting “who” or “whom” with “he/she” or “him/her.” If “he” or “she” fits grammatically, then “who” is correct.

If “him” or “her” fits, then “whom” is the correct pronoun. This method bypasses the complexities of sentence structure and focuses on the pronoun’s role.

When to Use “Those Who”

“Those who” is used when the pronoun “who” is acting as the subject of a verb within its clause. It refers to a group of people who are performing an action or are the subject of a statement.

Consider the sentence: “Those who arrive late will not be admitted.” Here, “who arrive late” is a relative clause modifying “those.” Within that clause, “who” is the subject of the verb “arrive.”

If you were to test this with the substitution method, you might think of a singular version: “He arrives late.” Since “he” fits, “who” is correct. Therefore, “those who” is the appropriate construction for a group performing the action.

Examples of “Those Who” in Action

The company offered a bonus to those who exceeded their sales targets. In this instance, “who exceeded their sales targets” describes the group receiving the bonus. “They exceeded their sales targets” makes grammatical sense, confirming “who” as the subject.

We should celebrate those who contribute positively to our community. The relative clause “who contribute positively to our community” identifies the individuals being celebrated. “They contribute positively” is a valid statement.

Only those who complete the training will receive a certificate. The subject of “complete” is “who.” “He completes the training” works, thus “those who” is correct.

When to Use “Those Whom”

“Those whom” is employed when the pronoun “whom” functions as the object of a verb or a preposition within its clause. It refers to a group of people who are receiving an action or are the object of a prepositional phrase.

Let’s examine the sentence: “We are looking for those whom we can trust.” In the relative clause “whom we can trust,” “whom” is the direct object of the verb “trust.”

Applying the substitution test: “We can trust him.” Since “him” fits, “whom” is the correct objective pronoun. Thus, “those whom” is used when the group is the recipient of the action or the object of a preposition.

Examples of “Those Whom” in Action

The award ceremony recognized those whom the committee deemed most deserving. Here, “whom the committee deemed most deserving” indicates the group being acted upon by the committee’s judgment. “The committee deemed them most deserving” is grammatically sound, validating “whom.”

She spoke with those whom she had previously consulted. The pronoun “whom” is the object of the preposition “with.” “She had previously consulted them” makes sense, showing that “whom” is the correct objective form.

This policy applies to all employees whom the company designates for further training. The relative clause is “whom the company designates for further training.” The company designates *them* for training. This confirms the objective case, requiring “whom.”

The Role of Prepositions

Prepositions are a significant clue when determining the use of “who” versus “whom.” If “who” or “whom” immediately follows a preposition (like “to,” “for,” “with,” “from,” “about”), then “whom” is almost always the correct choice.

This is because prepositions govern the objective case. The pronoun following a preposition is inherently an object.

For example, in the phrase “to whom it may concern,” “to” is a preposition, and “whom” is its object. If the sentence were “He is someone who I can talk to,” the preposition “to” comes at the end, but the clause is “I can talk to him,” making “whom” the correct choice if you were to rephrase it as “He is someone to whom I can talk.”

Prepositional Phrases and “Whom”

When a preposition directly precedes “whom,” the choice is straightforward. “The manager spoke to those whom she felt had earned a promotion.” “To” is the preposition, and “whom” is its object, referring to the people she spoke to.

Consider another example: “She gave the report to those whom she had assigned the task.” The preposition “to” governs “whom,” identifying the recipients of the report.

Even when the preposition is separated from “whom” by other words, the rule still applies. “The committee will select candidates about whom they have received positive feedback.” The preposition is “about,” and “whom” is its object.

Common Pitfalls and How to Avoid Them

One of the most common errors is using “who” when “whom” is required, often because the sentence structure is complex or the relative clause is embedded deeply.

The tendency to default to “who” because it sounds more natural or is more common in informal speech can lead to grammatical mistakes in formal writing.

Always remember the substitution test. If you can confidently replace the pronoun with “him” or “her,” then “whom” is the correct choice, regardless of how complex the sentence might seem.

Misplacing Prepositions

Sentences where prepositions are placed at the end can sometimes confuse people. For instance, “This is the person who I gave the book to.” If you rephrase this to place the preposition directly before the pronoun, it becomes “This is the person to whom I gave the book.”

In the original sentence, the clause is “I gave the book to [someone].” The “someone” is the object of the preposition “to.” Therefore, “whom” is correct: “This is the person whom I gave the book to.”

The key is to identify the grammatical function within the clause. If the pronoun is the object of a verb or preposition, use “whom.”

“Who” vs. “Whom” in Questions

The distinction between “who” and “whom” also applies to interrogative sentences (questions). When asking a question, the pronoun’s role as subject or object determines the correct word.

If the question asks about the subject of a verb, use “who.” For example, “Who is coming to the party?” Here, “who” is the subject of “is coming.” You could answer, “He is coming.”

If the question asks about the object of a verb or preposition, use “whom.” For example, “Whom did you invite?” Here, “whom” is the object of “invite.” You could answer, “I invited him.”

Formulating Interrogative Clauses

Consider the question: “Who did they elect?” The implied statement is “They elected him.” Since “him” fits, “whom” is correct: “Whom did they elect?”

Another example: “To whom should I address this letter?” The preposition “to” requires an object. The implied statement is “I should address this letter to him.” Thus, “whom” is correct.

Be mindful of embedded questions as well. “I wonder who will win the championship.” The embedded question is “Who will win the championship?” Here, “who” is the subject of “will win.”

The “Who” Clause as an Object

Sometimes, a clause beginning with “who” can itself function as the object of a verb or preposition in the main sentence. This can be a source of confusion.

For example: “I support those who advocate for change.” The main sentence is “I support [someone].” The word “someone” is the object of “support.” The phrase “those who advocate for change” functions as that object.

Within the relative clause “who advocate for change,” “who” is the subject of “advocate.” So, the structure is: [Main Clause Object] = [Noun Phrase + Relative Clause]. The pronoun within the relative clause is a subject.

This distinction is critical: the role of the pronoun *within its own clause* determines “who” or “whom,” not the role of the entire clause in the main sentence.

Clauses Acting as Objects vs. Pronouns within Clauses

Let’s analyze: “She praised the students who performed well.” The main verb is “praised.” The object of “praised” is “the students who performed well.” Within the relative clause “who performed well,” “who” is the subject of “performed.”

Contrast this with: “She praised the students whom she had personally tutored.” Again, the object of “praised” is “the students whom she had personally tutored.” However, within the relative clause “whom she had personally tutored,” “whom” is the object of “tutored” (she had tutored *them*).

The key is to dissect the relative clause itself to find the pronoun’s function.

The “Whom” Clause as an Object

Similarly, a clause beginning with “whom” can act as the object of a verb or preposition in the main sentence. This is more straightforward as “whom” is already an objective pronoun.

Consider: “The committee is responsible for selecting candidates whom they believe are best suited.” The main verb is “is responsible.” The object of “selecting” is “candidates whom they believe are best suited.”

Within the relative clause “whom they believe are best suited,” “whom” is the object of “believe” (they believe *them* to be best suited). The phrase “they believe” acts as an intervening clause, which can sometimes obscure the grammatical relationship.

However, focusing on “whom they believe are best suited,” if you remove “they believe,” you are left with “whom are best suited.” This is still grammatically incorrect in isolation, but the substitution test on the core relationship (“they believe whom”) reveals “whom” as the object of “believe.”

Intervening Clauses and Objective Pronouns

Phrases like “I think,” “you believe,” or “they assume” can interrupt the flow between the pronoun and its verb or preposition. These are often called parenthetical or intervening clauses.

Example: “We need to identify the employees whom, we believe, have the highest potential.” The intervening clause is “we believe.” The core relationship is between “whom” and “have the highest potential.” “We believe them to have the highest potential.” This confirms “whom.”

The substitution test remains robust even with these interruptions. Simply identify the verb or preposition that the pronoun is directly related to.

Formal vs. Informal Usage

In contemporary spoken English, “whom” is often omitted or replaced with “who,” especially in casual conversation. This trend has led to a perception that “whom” is archaic or overly formal.

However, in formal writing—such as academic papers, professional correspondence, legal documents, and published works—correct usage of “whom” is still expected and demonstrates a strong command of grammar.

While you might hear “Who did you see?” frequently, the formally correct question is “Whom did you see?” Recognizing this distinction is key to adapting your language to different contexts.

When Formality Matters

When writing a cover letter, a business proposal, or an essay for publication, adhering to strict grammatical rules, including the correct use of “whom,” is important. It signals professionalism and attention to detail.

Conversely, in a text message to a friend or a casual email, the strict adherence to “whom” might seem pedantic. The context dictates the level of formality required.

The goal is not to eliminate “whom” from your vocabulary but to use it appropriately when the context demands it, ensuring clarity and correctness in formal communication.

The Evolution of “Whom”

Language is dynamic, and “whom” has seen a decline in usage over time, particularly in spoken English. This shift is part of a broader trend where objective pronouns are less frequently distinguished from subjective ones in casual speech.

However, this evolution does not render “whom” incorrect; it merely changes its perceived frequency and formality. For many grammatical purposes, especially in written English, the distinction remains vital.

Linguists often refer to this as a process of grammatical simplification or regularization. While understandable, it’s important for writers to be aware of the traditional rules to maintain precision when needed.

Preserving Grammatical Precision

Even as language evolves, the ability to use “whom” correctly allows for a level of precision that “who” cannot always provide. It clearly marks the pronoun as an object, removing potential ambiguity.

In technical or legal writing, where absolute clarity is paramount, the distinction between “who” and “whom” can be crucial for interpreting meaning accurately.

Therefore, understanding and applying the rules for “whom” is not just about following convention; it’s about wielding the full power and precision of the English language.

Advanced Scenarios and Edge Cases

Occasionally, sentences can present tricky situations where the subject and object roles are not immediately apparent. These often involve complex subordination or unusual phrasing.

For instance, consider sentences where the relative pronoun appears to be both a subject and an object. This is rare but can occur. The key is always to break down the sentence into its smallest grammatical units.

When in doubt, always revert to the “he/him” substitution test on the specific clause in question. This method is remarkably effective even in the most convoluted sentence structures.

Navigating Ambiguity

If a sentence is so complex that even the substitution test yields ambiguity, it might be a sign that the sentence structure itself could be improved for clarity. Rewriting the sentence to make the subject-object relationship more explicit is often the best solution.

For example, instead of a very long sentence with an embedded “whom,” one might opt for two shorter, clearer sentences. This strategy enhances readability and ensures that the grammatical intent is unmistakable.

Ultimately, the goal of grammar is clear communication. If a construction is causing confusion, simplifying it is a valid and often preferred approach.

A Final Check: The Purpose of “Who” and “Whom”

“Who” and “whom” are relative pronouns that introduce subordinate clauses, providing additional information about a noun. Their function is to connect ideas and add descriptive detail.

Understanding their case—subjective for “who” and objective for “whom”—is the bedrock of correct usage. It’s about identifying the role each pronoun plays in its grammatical context.

By consistently applying the substitution test and considering the role of prepositions, you can confidently navigate the nuances of “those who” versus “those whom.”

Reinforcing the Core Concepts

Remember that “who” is for subjects (performers of action) and “whom” is for objects (receivers of action or objects of prepositions). This simple dichotomy is the most powerful tool in your grammatical arsenal.

Practice is key. The more you consciously apply these rules, the more natural and intuitive correct usage will become, even in complex sentences.

Mastering these distinctions not only improves your writing but also deepens your understanding of the English language’s elegant structure.
