جملات واره نسبی با سورها (همه آن‌ها، هیچ‌کدام از آن‌ها)

با یه ویرگول و of + whom/which، می‌تونی خیلی شیک جزئیات یه گروه رو توصیف کنی. all of whom, none of which

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]

مرور کلی

داری تو سرور دیسکوردت با ۵۰ تا ممبر می‌چرخی. می‌خوای به یه دوستت بگی که بعضی از اون‌ها آنلاین هستن. آیا می‌گی I have 50 members, and some of them are online یا می‌گی I have 50 members, some of whom are online؟
هر دوتاش درسته، ولی دومی باعث میشه صدات فوق‌العاده شیک و باکلاس به نظر بیاد. جمله‌واره‌های موصولی با کمیت‌سنج‌ها حکم «لول‌آپ» نهایی رو برای نوشتن انگلیسی‌ت دارن. اینا بهت اجازه میدن دو تا فکر رو توی یه جمله روان و حرفه‌ای ترکیب کنی.
به جای اینکه شبیه یه سری پیامک‌های کوتاه و بریده‌بریده به نظر برسی، شبیه یه داستان‌گو می‌شی. این قانون به خصوص توی نوشته‌های آکادمیک، گزارش‌های خبری و ایمیل‌های رسمی خیلی معروفه. اما فقط مال پروفسورها نیست!
توی کپشن‌های اینستاگرام و زیرنویس‌های نتفلیکس هم وقتی راوی داره یه گروه رو توصیف می‌کنه، اینو می‌بینی. بهش مثل یه پل نگاه کن. یه طرف، یه گروه داری (آدم‌ها یا چیزها).
طرف دیگه، یه جزئیات خاص درباره بخشی از اون گروه داری. کمیت‌سنج همون لنگریه که اینا رو به هم وصل می‌کنه. استفاده از این گرامر یکم شبیه پوشیدن کت‌وشلوار توی یه مهمونی پیتزا خوریه.
ممکنه اولش یکم رسمی به نظر بیاد، اما مطمئن باش همه تحت تأثیر استایلت قرار می‌گیرن. فقط حواست باشه پنیر نریزی رو ضمایر موصولیت. انگلیسی‌زبان‌ها عاشق کارایی هستن و این الگو پادشاه توصیفِ بهینه‌ست.
این باعث میشه هی یه فاعل رو تکرار نکنی، که از نظر زبانی دقیقاً مثل گیر کردن سوزن روی صفحه گرامافونه. اگه تا حالا حس کردی جملات انگلیسی‌ت زیادی «ساده» یا basic هستن، این همون فوت کوزه‌گری‌ایه که دنبالش بودی.

این گرامر چطور کار می‌کنه

در اصل، این گرامر درباره رابطه بین گروه‌ها و اجزای اون‌هاست. تو با یه ایده اصلی شروع می‌کنی: I have many followers. بعد می‌خوای یه جزئیات اضافه کنی: Most of them are from Brazil.
معمولاً از دو تا جمله استفاده می‌کنی. اما با این قانون، them رو با whom (برای آدم‌ها) یا which (برای اشیاء) عوض می‌کنی. جادو با کلمه of اتفاق میفته.
این کلمه، کمیت (مثل all, some, many, none) رو به ضمیر موصولی وصل می‌کنه. یه نکته حیاتی که باید یادت باشه: تو باید قبل از کمیت‌سنج از ویرگول (comma) استفاده کنی. بدون اون ویرگول، جمله مثل وای‌فای ضعیف وسط تماس زوم از هم می‌پاشه.
این ساختار یه جمله‌واره موصولی «غیرتوصیفی» (non-defining) می‌سازه. یعنی اطلاعاتی که داری اضافه می‌کنی توضیحات اضافه‌ست و برای شناسایی اون گروه ضروری نیست. چون اطلاعات اضافه‌ست، ما اون رو با ویرگول جدا می‌کنیم.
مثل یه نکته‌ایه که یواشکی در گوش خواننده‌ت زمزمه می‌کنی. اگه داری درباره ۲۰۰ تا ایمیل نخونده‌ت حرف می‌زنی (همه‌مون تجربه‌شو داریم) و ۵۰ تا از اون‌ها اسپم هستن، می‌گی: I have 200 emails, 50 of which are spam. دقت کن که چطور which به ایمیل‌ها برمی‌گرده.
این یه اشاره‌گره. به اسمی که الان گفتی اشاره می‌کنه و می‌گه: «هی، من دارم درباره یه بخش خاص از اون چیزها حرف می‌زنم.» وقتی الگو رو ببینی، به طرز عجیبی ساده‌ست، اما یکم ورزش ذهنی لازم داره تا جلوی خودت رو بگیری و نگی of them یا of they. کار نیکو کردن از پر کردن است، و خیلی زود مثل یه حرفه‌ای اینا رو توی انشاهات استفاده می‌کنی.

الگوی ساخت

1
ساختن این جملات از یه دستورالعمل خیلی خاص پیروی می‌کنه. بهش مثل ساختن یه لگو نگاه کن؛ اگه یه قطعه رو جا بندازی، کل سازه عجیب به نظر میاد. این مراحل رو دنبال کن تا جمله‌ت رو عالی بسازی:
2
با اولین فکر کاملت شروع کن (جمله‌واره اصلی). مثال: She bought five dresses.
3
یه ویرگول اضافه کن. این غیرقابل‌مذاکره‌ست! ویرگول نباشه، خبری از افتخار نیست.
4
کمیت‌سنج (quantifier) خودت رو انتخاب کن. این می‌تونه all, some, many, none, both, neither, a few یا حتی یه عدد خاص مثل three باشه.
5
کلمه of رو اضافه کن. این چسبِ این عبارته.
6
ضمیر موصولی درست رو انتخاب کن. از whom برای افراد و which برای اشیاء استفاده کن. اگه داری درباره مالکیت حرف می‌زنی، از whose + اسم استفاده کن (که البته این پیشرفته‌تره).
7
جمله رو با فعل و هر جزئیات دیگه‌ای تموم کن.

Memory Trick: قانون 'C-Q-O-R' رو به خاطر بسپار. Comma (ویرگول)، Quantifier (کمیت‌سنج)، ORelative pronoun (ضمیر موصولی). شبیه یه رمز مخفیه، و یه جورایی هم هست. این رمزِ اینه که شبیه یه انگلیسی‌زبان بومی به نظر برسی که واقعاً تو مدرسه حواسش جمع بوده. اگه شک داشتی که از whom استفاده کنی یا which، فقط از خودت بپرس: «آیا ضربان قلب داره؟» اگه بله، از whom استفاده کن. اگه نه (یا اگه گربه‌ست—شوخی کردم، کلاً برای حیوانات از which استفاده کن، هرچند بعضیا برای حیوانات خونگی از whom استفاده می‌کنن)، از which استفاده کن.

کی استفاده کنیم

این الگو توی موقعیت‌هایی می‌درخشه که می‌خوای اطلاعات زیادی بدی بدون اینکه تکراری باشی.
  • Formal Writing: این استاندارد طلایی برای مقالات دانشگاهیه. به جای نوشتن The researchers interviewed 100 people. 20 of them were students، می‌نویسی The researchers interviewed 100 people, 20 of whom were students. این نشون میده که روی نحو (syntax) پیچیده تسلط داری.
  • Professional Emails: وقتی داری به رئیست یا یه مشتری گزارش میدی. We launched three new features, all of which have received positive feedback. این خیلی بااعتمادبه‌نفس‌تر از دو تا جمله جداگانه به نظر میاد.
  • Storytelling: اگه داری یه پست وبلاگ درباره سفرهات می‌نویسی. I visited five islands, each of which had a unique culture. این یه ریتم قشنگ به روایتت میده.
  • Describing Groups: عالی برای حرف زدن درباره تیمت، کلکسیون صفحات گرامافونت، یا اپلیکیشن‌های روی گوشیت. I have 50 apps, most of which I never use. (همه‌مون تو این مورد گناهکاریم).
  • Job Interviews: وقتی داری تجربه‌ت رو توضیح میدی خوب جواب میده. I managed ten projects, several of which were international. این خیلی تأثیرگذارتر از اینه که بگی I managed ten projects. Some were international.
Politeness Levels:
  • Formal: I have three colleagues, all of whom are experts. (عالی برای خلاصه لینکدین).
  • Neutral/Informal: I have three colleagues, and they're all experts. (بهتر برای یه گپ دوستانه موقع قهوه خوردن).
  • Very Casual: I've got three workmates, all geniuses. (پیام دادن به یه دوست).
وقتی آنلاینی، ممکنه ببینی مردم اشتباهاً از all of who یا some of which استفاده می‌کنن. تو اون آدم نباش. توی نوشتن به قوانین رسمی بچسب، و همیشه جوری به نظر میای که انگار می‌دونی داری چیکار می‌کنی.
مثل این می‌مونه که بدونی سر یه شام اعیونی از کدوم چنگال استفاده کنی—ممکنه هر روز به این مهارت نیاز نداشته باشی، اما وقتی لازمش داری، واقعاً به چشم میاد.

اشتباهات رایج

رایج‌ترین اشتباه Comma Splice (اتصال اشتباه با ویرگول) یا Pronoun Trap (تله ضمیر) هست.
  • The Pronoun Trap: خیلی‌ها می‌گن I have two brothers, both of them are tall. توی انگلیسی، این یه 'run-on sentence' یا comma splice محسوب میشه. تو نمی‌تونی دو تا جمله کامل رو فقط با یه ویرگول به هم وصل کنی. یا نیاز به نقطه داری (...brothers. Both of them...)، یا یه حرف ربط (...brothers, and both of them...)، یا جمله‌واره موصولی مخصوص ما (...brothers, both of whom...).
  • Who vs. Whom: زبان‌آموزها اغلب دلشون می‌خواد بگن all of who. توی این الگوی خاص، بعد از حرف اضافه‌ای مثل of، تو باید از حالت مفعولی whom استفاده کنی. بله، حتی اگه فکر می‌کنی whom شبیه کلماتیه که از رمان‌های قرن نوزدهم اومده.
  • Forgetting the Comma: بعضی‌ها کلاً ویرگول رو فراموش می‌کنن. I have three cars none of which work. خوندن این گیج‌کننده‌ست. ویرگول علامتیه که نشون میده اطلاعات اضافی داره میاد.
  • Using 'That': شاید بدونی که that اغلب می‌تونه جایگزین which در جمله‌واره‌های موصولی بشه. اینجا نه. تو توی این ساختار موصولی خاص، هیچ‌وقت نمی‌تونی بگی all of that. همیشه which هست.
  • Verb Agreement: مطمئن شو که فعلت با کمیت‌سنج مطابقت داره. None of which IS (اگه درباره یه چیز حرف می‌زنی) در مقابل None of which ARE (اگه درباره چندتا چیز حرف می‌زنی). در واقع، با none، اغلب می‌تونی از هر دو استفاده کنی، اما all of which are قطعاً جمعه. نذار فعل‌هات تنها بمونن؛ مطمئن شو که با فاعل‌هاشون جورن!

مقایسه با الگوهای مشابه

مفیده که ببینی این الگو در مقایسه با «پسرعموهاش» چطوریه.
  • Standard Relative Clauses: The books which I bought are good. اینجا، which فقط یه ضمیر موصولی ساده‌ست. هیچ کمیت‌سنجی (all, some) وجود نداره. این مشخص می‌کنه که منظورت *کدوم* کتاب‌هاست.
  • Sentence with Conjunction: I have ten cousins, and many of them live in London. این کاملاً درسته و توی انگلیسی محاوره خیلی رایجه. این غیررسمی‌تر از many of whom هست. وقتی با دوستات هستی از این استفاده کن.
  • Two Separate Sentences: I have ten cousins. Many of them live in London. اگه مبتدی هستی این امن‌ترین روش برای حرف زدنه. واضحه، اما اگه همه جملاتت اینقدر کوتاه باشن ممکنه یکم «رباتیک» به نظر بیاد.
  • Participle Phrases: I have ten cousins living in London. این یه راه دیگه برای کوتاه کردن چیزهاست، اما اجازه استفاده از کمیت‌سنج رو نمیده (نمی‌تونی راحت بگی 'many of living in London').

Scenario 1: Talking about movies (Informal)

Alex: Have you seen the new Marvel movies?

Sam: I've seen all five, none of which I actually liked.

Alex: Wow, tough critic!

Manager: How are the new recruits doing?

Lead: We hired six developers, four of whom have already finished their orientation.

Manager: Excellent progress.

سؤالات رایج

Q

آیا واقعاً whom ضروریه؟ نمی‌تونم فقط از who استفاده کنم؟

توی این الگوی خاص (quantifier + of)، بله، whom تنها انتخاب گرامری درسته. استفاده از who اینجا برای بومی‌ها خیلی ضایع و توی چشم خواهد بود.

Q

می‌تونم این رو با whose استفاده کنم؟

آره! برای مثال: I have two friends, both of whose parents are teachers. این کمیابه و خیلی رسمی، ولی درسته.

Q

آیا این برای حیوانات کاربرد داره؟

معمولاً، ما برای حیوانات از which استفاده می‌کنیم. با این حال، اگه خیلی به حیوانات خونگیت نزدیکی، بعضی‌ها از whom استفاده می‌کنن. ولی اگه داری یه گزارش علمی درباره موش‌های آزمایشگاهی می‌نویسی، قطعاً به which بچسب.

Q

می‌تونم این رو اول جمله استفاده کنم؟

نه، یه جمله‌واره موصولی باید بعد از اسمی که توصیفش می‌کنه بیاد. این یه دنبال‌کننده‌ست، نه یه رهبر.

Q

اگه فقط یه دونه چیز داشته باشم چی؟ می‌تونم بگی one of which؟

قطعاً. I have three watches, only one of which still works. این یه راه عالی برای نشون دادن تضاده.

Q

برای پیامک دادن (texting) خوبه؟

ممکنه برای یه پیامک سریع یکم «زیادی» باشه. معمولاً، تو پیامک‌ها، ما فقط از دو تا جمله یا یه and ساده استفاده می‌کنیم. اما اگه می‌خوای کراشت رو با مهارت‌های گرامریت تحت تأثیر قرار بدی، برو بریم!

Q

از چه کمیت‌سنج‌هایی می‌تونم استفاده کنم؟

تقریباً هرچی! All, most, many, some, a few, few, none, both, neither, each, و اعداد مشخص.

Q

آیا ویرگول همیشه لازمه؟

بله. این‌ها جمله‌واره‌های موصولی غیرتوصیفی هستن، و توی انگلیسی، اون‌ها همیشه نیاز به ویرگول دارن. این قانونه (خب، قانون گرامر).

Q

می‌تونم از that به جای which استفاده کنم؟

نه. That نمی‌تونه بعد از حرف اضافه‌ای مثل of توی یه جمله‌واره موصولی بیاد. همیشه which هست.

Q

چطور پیشرفت کنم؟

سعی کن این رو توی محیط واقعی پیدا کنی. یه مقاله خبری توی BBC یا The New York Times بخون. تضمین می‌کنم توی پنج دقیقه حداقل یه of whom یا of which پیدا می‌کنی. وقتی دیدیش، سعی کن توی تکلیف نوشتاری بعدی‌ت ازش تقلید کنی.

تلفظ

/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.

نکات فرهنگی

This structure is a hallmark of high-level academic writing in the UK and US. Using it correctly can significantly improve the 'academic tone' of an essay.

In formal British contexts, 'whom' is preserved more strictly than in some casual American dialects.

Legal documents use this to be extremely precise about which parts of a contract or group of people are being discussed.

This structure stems from the Latin 'partitive genitive', where a part is taken from a whole.

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.
