परिमाणकों के साथ संबंधवाचक उपवाक्य (all of whom, none of which)

Use 'quantifier + of + whom/which' after a comma to elegantly describe parts of a previously mentioned group.

Grammar Rule in 30 Seconds

Use quantifiers like 'all' or 'some' with 'of whom' or 'of which' to add specific details about a group.

  • Use 'of whom' for people: 'I have two sisters, both of whom are doctors.'
  • Use 'of which' for things: 'He bought three cars, none of which work.'
  • Always use a comma before the quantifier to separate the extra information.
[Group], + [Number/Amount] + of + whom/which + [Action]

Overview

### Overview
जब आप किसी बड़े समूह के बारे में बात कर रहे हों और उसमें से कुछ खास लोगों या चीज़ों के बारे में अतिरिक्त जानकारी देना चाहें, तो Relative Clauses with Quantifiers का इस्तेमाल होता है। यह एक बहुत ही sophisticated तरीका है जिससे आप दो वाक्यों को जोड़कर एक ही वाक्य में ज़्यादा सटीक और elegant तरीके से अपनी बात कह सकते हैं। सोचिए, आप ऐसे कह सकते हैं: I have three siblings. All of them are older than me. इसे ज़्यादा बेहतर बनाने के लिए हम कह सकते हैं: I have three siblings, all of whom are older than me.
यह तरीका आपकी English को ज़्यादा precise और formal बनाता है, जो खासकर academic और professional settings में बहुत ज़रूरी है। B1 level पर, आप basic sentence structures से आगे बढ़ रहे हैं और ज़्यादा complex ideas को handle करना सीख रहे हैं। Relative clauses with quantifiers को समझना आपकी fluency और sophistication को बढ़ाने में एक बड़ा कदम है। यह structure basically non-defining relative clauses पर ही आधारित है, जो पहले से बताई गई बात के बारे में अतिरिक्त (non-essential) जानकारी देते हैं और हमेशा commas (,) से घिरे होते हैं। इस grammar rule को समझने से आपकी communication skills बेहतर होंगी।
### How This Grammar Works
Relative clauses with quantifiers, non-defining relative clauses का ही एक खास रूप हैं। ये पहले से बताई गई noun या pronoun के बारे में अतिरिक्त जानकारी देते हैं, और यह बताते हैं कि उस group में से कितने या कौन से हिस्से की बात हो रही है। इसके मुख्य elements हैं:
  1. 1Quantifier: यह बताता है कि समूह का कितना हिस्सा (जैसे all, some, many, most, none, one, two, both, half, few) या कितनी संख्या (जैसे one, two) की बात हो रही है।
  2. 2Preposition of: यह बहुत ज़रूरी है। इसके बिना sentence गलत हो जाएगा। यह बताता है कि quantifier, पहले बताई गई पूरी group का एक हिस्सा (subset) है। जैसे some of them में, some उस पूरे group them का एक हिस्सा है।
  3. 3Relative Pronoun: यह whom (लोगों के लिए) या which (चीज़ों, जानवरों या abstract concepts के लिए) होता है।
यह पूरा sequence (quantifier + of + relative pronoun) फिर आगे relative clause को introduce करता है।
of का महत्व:
of preposition का इस्तेमाल ज़रूरी है क्योंकि यह partitive relationship (भाग बताने वाला संबंध) बनाता है। इसके बिना, quantifier और main clause के noun/pronoun के बीच का grammatical link अधूरा रह जाता है।
  • गलत: The committee interviewed five candidates, all whom were highly qualified.
  • सही: The committee interviewed five candidates, all of whom were highly qualified.
Non-Defining Nature और Commas:
चूंकि ये clauses अतिरिक्त (non-essential) जानकारी देते हैं, ये हमेशा non-defining होते हैं। इसलिए, इन्हें हमेशा commas (,) से अलग किया जाता है। Clause से पहले एक comma लगता है, और अगर clause वाक्य के बीच में है, तो उसके बाद भी एक comma लगता है।
  • My colleagues, some of whom I had never met before, welcomed me warmly. (यहाँ some of whom I had never met before अतिरिक्त जानकारी है।)
  • अगर clause वाक्य के अंत में है, तो सिर्फ एक comma (शुरू में) लगता है:
She reviewed the reports, none of which contained the crucial data.
| Component | Role | Example Fragment |
| :------------------- | :------------------------------------------------------------------------ | :---------------------------------------- |
| Main Clause Noun | वह समूह (लोग या चीज़ें) जिसके बारे में बताया जा रहा है। | The delegates |
| Comma | Non-defining clause के लिए ज़रूरी punctuation। | , |
| Quantifier | अनुपात (most, many) या संख्या (two, one) बताता है। | many |
| of | ज़रूरी preposition, जो subset (हिस्सा) बताता है। | of |
| Relative Pronoun | Clause को जोड़ता है; लोगों के लिए whom, चीज़ों के लिए which। | whom |
| Relative Clause | उस subset के बारे में अतिरिक्त जानकारी देता है। | had expressed concerns. |
| Full Sentence | The delegates, many of whom had expressed concerns, debated for hours. | (पूरा cohesive वाक्य) |
### Formation Pattern
Relative clauses with quantifiers बनाने का एक खास pattern है। Relative pronoun (whom या which) preposition of के object के रूप में काम करता है। इसमें एक बहुत महत्वपूर्ण नियम है verb agreement का: relative clause में लगने वाला verb, quantifier के number (singular/plural) के अनुसार होना चाहिए, न कि main clause के noun के अनुसार। यह अक्सर confusion पैदा करता है, इसलिए इसे समझना बहुत ज़रूरी है।
लोगों के लिए Pattern (Pattern for People):
[Main Clause Noun (plural)], [quantifier] + of whom + [verb phrase]...
यहाँ whom का इस्तेमाल सिर्फ इंसानों के लिए होता है, क्योंकि preposition के बाद objective case (whom) ही आता है।
  • I contacted twenty potential clients, all of whom responded within an hour. (यहाँ verb responded plural quantifier all के अनुसार है।)
  • The research team includes several experts, one of whom specializes in AI ethics. (यहाँ verb specializes singular quantifier one के अनुसार है।)
  • She introduced her two brothers, both of whom work in finance. (यहाँ verb work plural quantifier both के अनुसार है।)
चीज़ों, जानवरों या Abstract Concepts के लिए Pattern (Pattern for Things, Animals, or Abstract Concepts):
[Main Clause Noun (plural or uncountable)], [quantifier] + of which + [verb phrase]...
यहाँ which का इस्तेमाल non-human referents के लिए होता है, जो of के object के रूप में काम करता है।
  • The company offers three distinct services, one of which is digital marketing. (यहाँ verb is singular quantifier one के अनुसार है।)
  • We reviewed hundreds of applications, most of which lacked the required experience. (यहाँ verb lacked plural quantifier most के अनुसार है, क्योंकि applications countable और plural है।)
  • The data, half of which was inconclusive, was eventually discarded. (यहाँ verb was quantifier half के अनुसार है। data यहाँ uncountable noun है, इसलिए half singular माना जाएगा।)
Common Quantifiers के लिए Verb Agreement Chart:
Verb का form इस बात पर निर्भर करता है कि quantifier singular है या plural, और वह countable noun के लिए है या uncountable.
| Quantifier | Referent Type (किसके लिए इस्तेमाल हो रहा है) | Verb Agreement (Verb कैसा होगा) | Example (People) | Example (Things/Concepts) |
| :-------------- | :------------------------------------------------------------------------ | :-------------------------------------- | :------------------------------------------------- | :------------------------------------------------------ |
| all | Countable plural / Uncountable (गिनने योग्य बहुवचन / अगणनीय) | Plural / Singular (बहुवचन / एकवचन) | students, all of whom are present | ideas, all of which are innovative / information, all of which is relevant |
| some | Countable plural / Uncountable | Plural / Singular | employees, some of whom live nearby | issues, some of which need attention / water, some of which is contaminated |
| many | Countable plural | Plural | attendees, many of whom asked questions | buildings, many of which were damaged |
| most | Countable plural / Uncountable | Plural / Singular | committee members, most of whom voted yes | documents, most of which contain errors / research, most of which is complete |
| none | Countable plural / Uncountable | Plural (common) / Singular (formal) (बहुवचन (आम) / एकवचन (औपचारिक)) | candidates, none of whom were suitable / none of whom was suitable | options, none of which are feasible / none of which is feasible |
| one | Countable singular (गिनने योग्य एकवचन) | Singular | directors, one of whom is retiring | proposals, one of which has been accepted |
| two, three...| Countable plural | Plural | witnesses, two of whom gave similar accounts | chapters, three of which focus on history |
| both | Countable plural (हमेशा दो) | Plural | siblings, both of whom reside abroad | approaches, both of which have merits |
| half | Countable plural / Uncountable | Plural / Singular | participants, half of whom completed the survey | budget, half of which was allocated / profits, half of which go to charity |
| few/a few | Countable plural | Plural | volunteers, a few of whom arrived early | suggestions, few of which were practical |
Quantifiers जैसे all, some, most, और half countable (जैसे students, books) और uncountable nouns (जैसे information, water) दोनों के लिए इस्तेमाल हो सकते हैं। जब ये countable plural noun के लिए हों, तो verb plural होगा। जब uncountable noun के लिए हों, तो verb singular होगा। none के लिए, दोनों singular और plural verb कभी-कभी स्वीकार्य होते हैं, लेकिन countable nouns के साथ plural ज़्यादा आम है, जबकि singular formal contexts में सही है।
### When To Use It
यह grammatical structure आपकी English communication में clarity, conciseness और formal/academic tone लाने के लिए बहुत उपयोगी है। यह complex information को efficiently deliver करने में मदद करता है, जिससे आप groups के अंदर के nuanced relationships को बेहतर ढंग से articulate कर पाते हैं। इसके strategic uses को समझने से आपकी written और spoken proficiency बढ़ेगी।
  • किसी subset के बारे में precise details देने के लिए:
जब आपने किसी group का ज़िक्र किया हो और आपको उस group के किसी हिस्से (number, proportion, या characteristic) के बारे में अतिरिक्त जानकारी देनी हो, तो इस structure का प्रयोग करें। यह जानकारी को smoothly integrate करता है, जिससे flow बेहतर होता है।
  • Simple तरीका: The committee reviewed seven proposals. Two of the proposals were rejected. (कम cohesive)
  • Better तरीका: The committee reviewed seven proposals, two of which were rejected. (ज़्यादा concise और integrated)
  • एक और उदाहरण: We interviewed ten candidates for the position, most of whom had relevant experience.
  • Formal और Academic contexts में:
आप यह structure academic papers, official reports, formal presentations, और sophisticated essays में अक्सर देखेंगे। यह एक precise, economical, और polished writing style देता है, जो इन settings में बहुत appreciated है। यह advanced linguistic control दर्शाता है।
  • The research analyzed a cohort of 500 patients, a third of whom exhibited positive responses to the treatment.
  • The legislation introduced several new clauses, none of which significantly altered the original intent.
  • Cohesion बढ़ाने और repetition से बचने के लिए:
यह construction आपको अलग-अलग sentences का प्रयोग करने या noun/pronoun phrase (जैसे some of them, all of them) को बार-बार दोहराने से बचने में मदद करता है। इससे narrative या argument ज़्यादा fluid बनता है।
  • Repetitive: The delegates discussed several key issues. Some of them were quite controversial.
  • Better: The delegates discussed several key issues, some of which were quite controversial.
  • Formal Speeches और Presentations में:
जब आप किसी group (जैसे company employees, conference attendees) के बारे में बात कर रहे हों और उनके किसी subset की उपलब्धियों या विशेषताओं को उजागर करना चाहते हों, तो यह structure बहुत प्रभावी होता है।
  • We are proud of our team, many of whom have worked tirelessly to achieve this milestone.
  • The event was a great success, both of which were due to the excellent organization and participant engagement. (यहाँ both दो चीज़ों को refer कर रहा है, जो event की success के कारण थे।)
  • Complex Comparisons में:
जब आप दो groups की तुलना कर रहे हों और एक group के किसी subset के बारे में कुछ कहना हो, तो यह structure उपयोगी हो सकता है।
  • The first draft had 50 pages, most of which needed significant revision.
  • The revised version is much shorter, few of which contain the original errors.
संक्षेप में: इस structure का प्रयोग तब करें जब आप किसी group के बारे में बात कर रहे हों और आपको उस group के एक हिस्से के बारे में अतिरिक्त, non-essential जानकारी देनी हो, खासकर जब आप अपनी भाषा को ज़्यादा formal, concise, और sophisticated बनाना चाहते हों।
### Common Mistakes
Native Hindi speakers के लिए इस structure में कुछ common mistakes हो सकती हैं, जो अक्सर Hindi grammar के influence की वजह से होती हैं।
  1. 1of का omission (छोड़ देना):
* Mistake: The students, all whom were present, received their books.
* Why it happens: Hindi में हम अक्सर सब या कुछ के बाद का/के/की (equivalent of of) का प्रयोग नहीं करते जब वह सीधे किसी noun/pronoun से जुड़ता है। जैसे, मेरे सभी दोस्त (all my friends), कुछ लोग (some people)। English में all of whom, some of which में of ज़रूरी है। यह of ही all को whom (जो कि students को refer कर रहा है) से जोड़ता है।
* Correct: The students, all of whom were present, received their books.
  1. 1Verb Agreement में गलती (Quantifier के बजाय Main Clause Noun के अनुसार Verb लगाना):
* Mistake: The reports, one of which were very important, were submitted late.
* Why it happens: Hindi में verb अक्सर subject (कर्ता) के अनुसार बदलता है। यहाँ reports plural है, तो गलती से लोग were लगा देते हैं। लेकिन English में, इस structure में verb का agreement quantifier (one, two, all, some, etc.) से होता है। one singular है, इसलिए verb भी singular होना चाहिए।
* Correct: The reports, one of which was very important, were submitted late.
  1. 1whom और which के बीच confusion:
* Mistake: I met the artists, some of which were very talented.
* Why it happens: Hindi में जो शब्द इंसानों और चीज़ों दोनों के लिए इस्तेमाल होता है। English में who/whom (लोगों के लिए) और which (चीज़ों के लिए) अलग-अलग हैं। Hindi speakers कभी-कभी इस distinction को भूल जाते हैं।
* Correct: I met the artists, some of whom were very talented.
  1. 1Comma का गलत प्रयोग:
* Mistake: The participants all of whom completed the survey were entered into a draw. (Comma नहीं है)
* Why it happens: Hindi में हम वाक्यों को जोड़ने के लिए अक्सर commas का उतना प्रयोग नहीं करते जितना English में होता है, खासकर non-defining clauses में। इस structure में, क्योंकि यह non-defining (अतिरिक्त जानकारी) है, comma लगाना ज़रूरी है।
* Correct: The participants, all of whom completed the survey, were entered into a draw.
इन गलतियों से बचने के लिए, हमेशा of के प्रयोग, verb agreement (quantifier के साथ), whom/which के सही चुनाव, और commas के सही placement पर ध्यान दें।
### Contrast With Similar Patterns
Relative clauses with quantifiers को समझने के लिए, इन्हें कुछ मिलते-जुलते patterns से compare करना helpful होगा:
1. Simple Relative Clauses (Defining vs. Non-Defining):
* Defining Relative Clauses: ये essential जानकारी देते हैं और sentence का meaning बदलने के लिए ज़रूरी होते हैं। इनमें comma नहीं लगता।
* The student who scored the highest got a scholarship. (यहाँ who scored the highest essential है, यह बताता है कि कौन से student को scholarship मिली।)
* Non-Defining Relative Clauses: ये अतिरिक्त, non-essential जानकारी देते हैं और commas से घिरे होते हैं।
* Ravi, who scored the highest, got a scholarship. (यहाँ who scored the highest अतिरिक्त जानकारी है, हम जानते हैं कि Ravi कौन है।)
Relative clauses with quantifiers हमेशा non-defining होते हैं, इसलिए वे हमेशा commas के साथ आते हैं।
2. Relative Clauses with Pronouns (without Quantifiers):
जब आप group के सभी members या किसी specific member की बात कर रहे हों, लेकिन quantifier (all, some, none, one) का प्रयोग न हो।
* Defining: The students who attended the lecture will get extra credit. (Essential)
* Non-Defining: The students, who attended the lecture, were praised by the professor. (Additional info about students we already know)
3. Using all/some/none etc. + of + Pronoun (without whom/which):
यह structure तब इस्तेमाल होता है जब pronoun (like them, us, you, it) पहले से ही main clause में मौजूद हो या context से clear हो। यह ज़्यादा informal होता है।
* Formal (Relative Clause with Quantifier): The team members, all of whom are dedicated, celebrated their success.
* Informal (Pronoun): The team members celebrated their success, and all of them were happy. या The team members celebrated their success; all of them were happy.
यहाँ all of them एक separate clause या phrase की तरह काम कर रहा है, जबकि all of whom relative clause का हिस्सा है।
| Feature | Relative Clause with Quantifier (all of whom) | Simple Non-Defining Relative Clause (who) | Informal Structure (all of them) |
| :----------------------------- | :---------------------------------------------- | :------------------------------------------ | :--------------------------------------- |
| Structure | ..., quantifier + of + whom/which + verb... | ..., who/which + verb... | ...; quantifier + of + pronoun. / ... and quantifier + of + pronoun. |
| Function | Adds extra info about a subset of a group. | Adds extra info about a specific noun. | Connects related ideas, often less formally. |
| Comma Usage | Always uses commas (non-defining). | Always uses commas (non-defining). | Often uses semicolon or conjunction (and). |
| Example (People) | The doctors, all of whom were specialists, discussed the case. | Dr. Sharma, who is a renowned surgeon, led the team. | The doctors discussed the case; all of them were specialists. |
| Example (Things) | The books, most of which were old, needed repair. | The book, which I bought yesterday, is interesting. | The books needed repair; most of them were old. |
| Formality Level | Formal / Academic | Formal / Academic | Informal / Neutral |
Relative clauses with quantifiers, therefore, offer a specific way to integrate information about a *portion* of a previously mentioned group, using a formal structure that links directly back to the main clause. The informal structure separates the information more distinctly.
### Quick FAQ
1. क्या मैं all of which का प्रयोग इंसानों के लिए कर सकता हूँ?
नहीं, बिल्कुल नहीं। whom का प्रयोग सिर्फ इंसानों (people) के लिए होता है, और which का प्रयोग चीज़ों (things), जानवरों (animals), या abstract concepts के लिए होता है।
  • सही: The employees, all of whom received a bonus, were happy.
  • गलत: The employees, all of which received a bonus, were happy.
2. क्या of के बिना यह structure काम कर सकता है?
नहीं, of इस structure के लिए gramatically essential है। quantifier + of + relative pronoun एक unit की तरह काम करता है। of के बिना यह गलत होगा।
  • गलत: The candidates, many which were qualified, were interviewed.
  • सही: The candidates, many of which were qualified, were interviewed.
3. अगर quantifier singular है (जैसे one), तो verb singular क्यों लगता है?
Verb का agreement quantifier के साथ होता है, न कि main clause के noun के साथ। Quantifier यह बताता है कि आप group के कितने हिस्से की बात कर रहे हैं।
  • The proposals, one of which was accepted, are listed below. (यहाँ one singular है, इसलिए verb was singular है, भले ही proposals plural हो।)
  • The students, one of whom is my cousin, are from Delhi. (यहाँ one singular है, इसलिए verb is singular है, भले ही students plural हो।)
4. क्या मैं इस structure को informal बातचीत में इस्तेमाल कर सकता हूँ?
हाँ, आप कर सकते हैं, लेकिन यह थोड़ा formal या academic लग सकता है। Informal बातचीत में, लोग अक्सर इसे सरल वाक्यों में तोड़ देते हैं या all of them, some of us जैसे structures का प्रयोग करते हैं।
  • Formal: The delegates, several of whom raised concerns, eventually reached an agreement.
  • Informal: The delegates reached an agreement. Several of them had raised concerns. या Several delegates raised concerns, and they eventually reached an agreement.
लेकिन B1 level पर, इस formal structure को सीखने और समझने से आपकी English का standard ज़रूर बढ़ेगा।

💡

The Comma is Key

Always put a comma before the quantifier. These are non-defining clauses, so the comma tells the reader 'here is some extra info'.
⚠️

Never 'of who'

Even if you hate the word 'whom', you must use it here. 'Of who' is grammatically incorrect in all standard dialects.
🎯

Use for Numbers

This is the best way to include statistics in your writing without making it sound like a list. 'We tested ten samples, three of which failed.'

Smart Tips

Try combining them with 'of whom' or 'of which' to make your writing flow better.

I have ten employees. Most of them work remotely. I have ten employees, most of whom work remotely.

If there is a preposition like 'of' right before it, it is ALWAYS 'whom'.

Many of who... Many of whom...

उच्चारण

/ɔːl əv huːm/

Stress on the Quantifier

In these clauses, the quantifier (all, some, none) usually receives the primary stress to emphasize the amount.

some-əv-which

The 'of' reduction

The word 'of' is often reduced to a weak 'schwa' sound /əv/.

Non-defining pause

I have two brothers [pause] both of whom are doctors.

The pause (indicated by the comma) shows that the following information is extra.

याद करें

स्मृति सहायक

Remember: 'Whom' for the 'Home-sapiens' (people), 'Which' for the 'Witch's' broom (things).

दृश्य संबंध

Imagine a large circle representing a group. Inside, a smaller circle is highlighted with a label like '3 of whom' or 'some of which'. This shows you are focusing on a subset.

Rhyme

No. In this specific structure (after a quantifier and 'of'), you can only use `which` for things and `whom` for people.

It is quite formal. In casual speech, most people say `I have three brothers and all of them are...` rather than using `all of whom`.

Yes. These are non-defining relative clauses, which always require a comma to separate the extra information from the main clause.

Absolutely! Any quantifier works: `one`, `two`, `several`, `many`, `a few`, `none`, `all`, etc.

Usually, we use `which` for animals. However, if the animals are pets with names, some people use `whom`, though `which` is always safe.

It depends on the noun. Usually, it takes a plural verb if the group is plural: `None of which are...` but in very formal English, some prefer the singular `is`.

No, the relative clause must follow the noun it describes. You must introduce the group before you can quantify it.

Use `both` specifically for two people. Use `all` for three or more.

Japanese does not use relative pronouns like 'which' or 'whom'.

Arabic partial

منهم (minhum) / منها (minha)
