The grammar puzzle of Many of Who or Many of Whom often creates confusion in English learning, especially when learners face a language maze full of twists and turns while navigating language rules in sentence building and sentence formation. When people try to string words together from a bunch of words, their word knowledge and vocabulary must follow clear language structure, language patterns, and linguistic patterns. Without strong grammar awareness and linguistic awareness, many writers struggle with grammar confusion, which affects communication, communication skill, and writing skill. Even native speakers sometimes experience speaker confusion, creating head scratchers where heads scratch while solving a grammar puzzle or language puzzle in real writing context such as essay writing, email writing, and other forms of communication writing.
From a learning perspective, improving language clarity requires deeper contextual meaning, better contextual understanding, and accurate language usage in English usage. During grammar learning, students build stronger interpretation, comprehension, and textual understanding by observing linguistic context, doing language observation, and following a structured learning process through language exploration. These activities improve sentence clarity, expression clarity, and reduce grammar complexity and language difficulty. In classrooms and writing workshops, effective learning guidance and a clear instructional context help learners develop communication clarity and stronger textual interpretation.
A common grammar mistake occurs when writers use many of who instead of many of whom in a sentence or written sentence. Many learners have wondered whether this is correct, but correctness depends on the grammar rule explained in English grammar. The rule explanation focuses on who vs whom and the difference between them in the English language. In plain English, who often functions differently from whom, because whom acts as an object pronoun while who may function as a relative pronoun within a sentence structure or larger grammar structure. Understanding grammar usage, reading usage explanation, and identifying the correct form rather than the incorrect form prevents sentences that sound wrong and improves grammatical correctness.
Many of Who or Many of Whom — Quick Answer
The correct form is usually:
✅ many of whom
❌ many of who
Why? Because whom is an object pronoun, and after the word of, English grammar requires an object pronoun.
Example:
- The students, many of whom passed, were happy.
- The people, many of whom I met, were friendly.
The word of is the key. After a preposition like of, to, for, with, or by, you normally use whom, not who.
Who vs Whom — The Rule Everyone Forgets
The difference between who and whom is simple, but sentence structure makes it confusing.
| Pronoun | Use | Grammar Role | Example |
| who | subject | does the action | Who called you? |
| whom | object | receives the action | Whom did you call? |
Who = subject- Whom = object
Grammar experts explain it like this:
“Who refers to someone performing the action… whom refers to someone receiving the action.”
Examples:
- Who wrote the letter?
- Whom did you invite?
- The person who arrived
- The person whom I met
When you understand this rule, many of whom become easy.
Why “Many of Whom” Is Correct
Look at this sentence:
The players, many of whom were injured, missed the game.
Break it apart:
- players → main subject
- many of whom → extra information
- of whom → object of the preposition
Because of is a preposition, the pronoun must be an object.
Correct pattern:
many of + object pronoun
Examples:
| Correct | Incorrect |
| many of whom | many of who |
| some of whom | some of who |
| all of whom | all of who |
| none of whom | none of who |
Grammar guides say phrases like some of whom / many of whom / each of whom almost always require whom.
The Real Grammar Structure Behind “Many of Whom”
To understand this fully, you need to see the structure.
Sentence:
The guests, many of whom I know, arrived early.
Structure:
- guests → main noun
- many → quantity
- of → preposition
- whom → object of preposition
- I know → clause
English rule:
A preposition takes an object.
Common prepositions:
- of

| who | whom |
| he | him |
| she | her |
| they | them |
| we | us |
Example test:
- many of them → correct
- many of they → wrong
So:
- many of whom → correct
- many of who → wrong

Why People Say “Many of Who” Even Though It’s Wrong
Many native speakers say many of who, especially in conversation.
Why?
Spoken English is less strict
In everyday speech, people often use who instead of whom.
Grammar experts note that whom sounds formal and is used more in writing than speech.
Whom feels old-fashioned
Modern English uses who more often.
Example:
- Who did you talk to? (common)
- To whom did you talk? (formal)
Both may be understood, but only one follows strict grammar.
People avoid whom
Many writers avoid whom because it feels complicated.
But after of, the formal rule still prefers whom.
When You Must Use “Whom” in Formal Writing
In casual speech, the rule may not matter.
In formal writing, it does.
Use many of whom in:
- academic essays
- exams
- research papers
- business writing
- legal documents
- books
- professional emails
Example:
The candidates, many of whom had advanced degrees, applied for the job.
Using many of who here would look incorrect.
The Easy Trick — Him / Them Test
This trick works almost every time.
Replace who/whom with:
- he / him
- they / them
If him / them fits → use whom
If he / they fits → use who
Example:
Many of them were late → correct
Many of they were late → wrong
So:
Many of whom were late → correct
Another example:
I met them → object
I met whom → correct
Grammar experts recommend this test because it shows whether the pronoun is subject or object.

- The workers, many of ___ tried, succeeded.
Answers:
- whom
- whom
- whom
- whom
- whom
If of comes before the pronoun, the answer is almost always whom.
Why English Still Keeps “Whom”
Even though people use it less, whom still exists because English keeps subject and object forms.
Examples:
| Subject | Object |
| I | me |
| he | him |
| she | her |
| they | them |
| who | whom |
Without object forms, sentences could become unclear.
Example:
- To who did you give it?
- To whom did you give it?
The second is clearer in formal grammar.

FAQs
Q1. Is many of who correct in English grammar?
No, many of who is usually incorrect in standard English usage. The correct form is many of whom because the pronoun comes after the preposition of, and in formal grammar rules, an object pronoun is required after a preposition. Since whom functions as an object pronoun, it fits the sentence structure correctly and improves grammatical correctness and language clarity.
Q2. Why is many of whom considered correct?
The phrase many of whom is correct because whom acts as the object of the preposition of. In English grammar structure, prepositions such as of, to, for, with, by, and about must be followed by an object pronoun. This rule is part of standard grammar usage and helps maintain proper sentence formation and linguistic patterns in both formal writing and academic writing.
Example:
- Correct: Many of whom were present understood the grammar rule.
- Incorrect: Many of who were present understood the grammar rule.
Q3. What is the difference between who and whom?
The difference comes from their grammatical function in sentence structure.
| Pronoun | Function | Example |
| Who | Subject pronoun | Who wrote the sentence? |
| Whom | Object pronoun | Whom did you invite? |
In complex sentence building, especially in relative clauses, choosing the correct pronoun depends on whether the word acts as a subject or an object inside the clause. This understanding improves grammar awareness and reduces grammar confusion.
Q4. Why do learners get confused about who vs whom?
Learners often experience grammar confusion because modern English usage sometimes ignores strict grammar rules in casual communication. In spoken English, many speakers use who in place of whom, which creates speaker confusion and makes the grammar puzzle harder to solve. Without strong linguistic awareness and contextual understanding, writers may struggle when writing essays, emails, or formal documents.
Q5. Can native speakers make mistakes with many of who / many of whom?
Yes, even native speakers sometimes face head-scratchers when building sentences, especially in formal writing contexts. While everyday speech may allow flexibility, academic writing, professional communication, and instructional writing usually require correct grammar usage. This is why grammar learning and language observation are important parts of improving communication skill and writing skill.
Q6. How can learners remember the rule easily?
A simple learning tip is:
If the word comes after of, use whom.
This rule works in most grammar situations and helps learners reduce language difficulty while improving sentence clarity and expression clarity.
Example:
- Many of whom attended the workshop.
- Several of whom understood the lesson.
- Few of whom completed the exercise.
Practicing this pattern through language exploration and structured learning helps build stronger comprehension and textual understanding.
Q7. Is it always wrong to use who instead of whom?
Not always in informal conversation, but in formal English usage, academic writing, and professional communication writing, using whom after a preposition is the correct and recommended form. Following correct grammar rules ensures better communication clarity and avoids sentences that sound wrong to careful readers.
Conclusion
Understanding the grammar puzzle of many of who vs many of whom becomes easier when learners focus on grammar structure, linguistic patterns, and contextual meaning instead of guessing. The key rule is simple but important: after the preposition of, the correct form is usually whom, because it functions as an object pronoun inside the sentence structure.
When writers develop stronger grammar awareness and linguistic awareness, they can avoid common grammar mistakes that often appear during sentence building, essay writing, email writing, and other forms of communication writing. Through careful language observation, guided learning, and consistent practice, learners improve sentence clarity, expression clarity, and overall communication skill.
