Formal Arabic often turns an entire preceding event into the antecedent of a new relative clause. English does this with a supplementary which: “The deadline changed, which confused everyone.” Modern Standard Arabic does not normally use bare الذي as a universal translation of that sentential which. Instead, it packages the earlier proposition in a definite “shell” such as الأمر “the matter/fact,” then modifies that shell: الأمر الذي أربك الجميع.
Two related structures, وهو ما... and مما..., perform similar discourse work without containing الذي. Keeping their grammar distinct prevents a useful writing pattern from turning into the false rule “put الذي after a comma.” Their use of ما builds on Headless Relatives with من and ما.
The core pattern: الأمر الذي
The sequence الأمر الذي literally means “the matter/fact which.” In discourse-linking use, الأمر retrieves the whole proposition before it rather than one masculine noun.
تغير موعد المؤتمر، الأمر الذي أربك كثيرا من المشاركين.
taghayyara mawʿidu l-muʾtamari, al-ʾamru lladhī ʾarbaka kathīran mina l-mushārikīn.
The conference date changed, which confused many participants. (formal)
أقرت اللجنة الميزانية كاملة، وهو الأمر الذي سمح ببدء المشروع.
ʾaqarrati l-lajnatu l-mīzāniyyata kāmilatan, wa-huwa l-ʾamru lladhī samaḥa bi-badʾi l-mashrūʿ.
The committee approved the full budget, which allowed the project to begin. (formal)
The optional framing وهو makes the appositional relationship especially explicit: “and it is the matter that...” Both versions are characteristic of news, reports, academic prose, and prepared speech (formal). In casual regional speech, speakers generally use dialect-specific connectors instead (regional: varies by region).
Why definiteness still controls the structure
The relative pronoun appears because الأمر is definite. An indefinite shell noun takes a directly following adjectival clause without الذي.
حدث أمر أدى إلى تأخير الرحلة.
ḥadatha ʾamrun ʾaddā ʾilā taʾkhīri r-riḥla(h).
Something happened that delayed the trip.
تأخر إصدار التصريح، وهو الأمر الذي أدى إلى تأجيل الرحلة.
taʾakhkhara ʾiṣdāru t-taṣrīḥi, wa-huwa l-ʾamru lladhī ʾaddā ʾilā taʾjīli r-riḥla(h).
Issuance of the permit was delayed, which led to the flight being postponed. (formal)
In the first sentence, أمر introduces an unspecified event. In the second, الأمر anaphorically identifies the already stated delay. The architecture is therefore ordinary Arabic definiteness grammar applied across sentences.
Other shell nouns and agreement
الأمر الذي is productive, not an immutable conjunction. A writer can choose a shell noun that names the relationship more precisely, and the relative pronoun then agrees with that noun.
| Shell | Agreement | Typical discourse meaning |
|---|---|---|
| الأمر الذي | masculine singular | the matter/fact which |
| النتيجة التي | feminine singular | the result which |
| الخطوتان اللتان | feminine dual, nominative | the two steps which |
| القراران اللذان | masculine dual, nominative | the two decisions which |
| الإجراءات التي | nonhuman plural → feminine singular | the measures which |
انخفضت التكاليف وارتفعت سرعة الإنتاج، وهما النتيجتان اللتان كنا ننتظرهما.
ʾinkhafaḍati t-takālīfu wa-rtafaʿat surʿatu l-ʾintāji, wa-humā n-natījatāni llatāni kunnā nantaẓiruhumā.
Costs fell and production speed increased—the two results we had been waiting for. (formal)
The dual shell requires dual هما، النتيجتان، اللتان, plus resumptive ـهما because the two results are the object of ننتظر. If the shell were accusative or genitive in its larger sentence, النتيجتين اللتين would use the oblique dual forms.
For nonhuman plural الإجراءات, formal MSA normally uses feminine singular التي and ـها, not human plural الذين/ـهم.
Resumptives inside discourse-linking clauses
The shell noun can be the subject of the relative clause, in which case no resumptive object is added: الأمر الذي أدى إلى.... If it has an object, possessive, or prepositional role, the clause normally contains the corresponding suffix.
تجاهلت الإدارة التحذير، وهو الأمر الذي حذرنا منه منذ البداية.
tajāhalati l-ʾidāratu t-taḥdhīra, wa-huwa l-ʾamru lladhī ḥadhdharnā minhu mundhu l-bidāya(h).
Management ignored the warning, which is exactly what we had warned about from the beginning. (formal)
Here منه is required by حذر من. English strands about or suppresses it within what we warned about; Arabic completes من with ـه.
رفض المجلس الحل، وهو القرار الذي توقعنا عواقبه.
rafaḍa l-majlisu l-ḥalla, wa-huwa l-qarāru lladhī tawaqqaʿnā ʿawāqibah.
The council rejected the solution—a decision whose consequences we had anticipated. (formal)
The suffix in عواقبه is possessive: “its consequences.” Calling every suffix a direct-object pronoun would miss this distinction.
وهو ما: “which is what...”
وهو ما combines وهو “and it is” with headless relative ما. It retrieves an earlier proposition and makes the following clause a comment on it.
زادت الشركة ساعات التدريب، وهو ما طالب به الموظفون منذ أشهر.
zādati sh-sharikatu sāʿāti t-tadrībi, wa-huwa mā ṭālaba bihi l-muwaẓẓafūna mundhu ʾashhur.
The company increased the training hours, which is what employees had requested for months. (formal)
The suffix in به belongs to طالب بـ “call for/request.” ما does not agree with “hours”; it refers to the proposition “the company increased the training hours.” This structure often corresponds more closely to English which is what than to simple which.
مما: common result link, different grammar
مما is written as one word because it combines preposition من with relative ما. In expository prose, مما أدى إلى... conventionally presents a result: “which led to...” or “thereby leading to...”
هطلت أمطار غزيرة طوال الليل، مما أدى إلى إغلاق بعض الطرق.
haṭalat ʾamṭārun ghazīratun ṭawāla l-layli, mimmā ʾaddā ʾilā ʾighlāqi baʿḍi ṭ-ṭuruq.
Heavy rain fell throughout the night, which led to the closure of some roads. (formal)
لم تصل البيانات في موعدها، مما جعل المقارنة مستحيلة.
lam taṣili l-bayānātu fī mawʿidihā, mimmā jaʿala l-muqāranata mustaḥīla(h).
The data did not arrive on time, which made the comparison impossible. (formal)
It is tempting to memorize مما as a single causal conjunction, but its range is broader. In هذا مما نحتاج إليه, it means “this is among what we need.” The result reading arises from the whole construction and context, especially with verbs such as أدى إلى and جعل.
Near and far demonstratives in anaphoric links
هذا tends to present a proposition as immediate or current; ذلك can recall it with greater discourse distance or contrast. Neither distance is purely physical.
هذه هي النتيجة التي توصلنا إليها اليوم، وتلك هي النتيجة التي رفضها الفريق سابقا.
hādhihi hiya n-natījatu llatī tawaṣṣalnā ʾilayhā l-yawma, wa-tilka hiya n-natījatu llatī rafaḍahā l-farīqu sābiqā.
This is the conclusion we reached today, while that is the conclusion the team rejected earlier.
The feminine suffixes إليها، ـها resume النتيجة. Demonstrative distance changes the writer's framing, not relative-pronoun agreement.
Punctuation and register
Arabic commonly places a comma ، before a supplementary link, but punctuation does not create the grammar. الذي after a comma still requires an antecedent. These extended links are at home in reports, journalism, policy documents, and academic argument (formal/academic). Repeating الأمر الذي in every sentence becomes heavy; alternate it with direct coordination, causal connectors, or a new sentence when the logical relation is already clear.
Common Mistakes
Leaving the noun indefinite after a demonstrative
❌ هذا قرار الذي غير الخطة.
Incorrect for “this decision changed the plan” — hādhā + an identified noun requires al-qarār.
✅ هذا القرار غير الخطة.
hādhā l-qarāru ghayyara l-khuṭṭa(h).
This decision changed the plan.
Using الذي after an indefinite antecedent
❌ حدث أمر الذي أخر الرحلة.
Incorrect — indefinite ʾamrun takes a directly following adjectival clause.
✅ حدث أمر أخر الرحلة.
ḥadatha ʾamrun ʾakhkhara r-riḥla(h).
Something happened that delayed the trip.
Treating bare الذي as English sentential “which”
❌ تغير الموعد، الذي أربك المشاركين.
Incorrect for a link to the whole preceding proposition — alladhī has no explicit masculine singular antecedent here.
✅ تغير الموعد، الأمر الذي أربك المشاركين.
taghayyara l-mawʿidu, al-ʾamru lladhī ʾarbaka l-mushārikīn.
The time changed, which confused the participants. (formal)
Stranding a preposition inside the relative clause
❌ تجاهلوا التحذير، وهو الأمر الذي حذرنا من.
Incorrect — min requires a resumptive suffix referring to al-ʾamr.
✅ تجاهلوا التحذير، وهو الأمر الذي حذرنا منه.
tajāhalū t-taḥdhīra, wa-huwa l-ʾamru lladhī ḥadhdharnā minh.
They ignored the warning, which is what we had warned about. (formal)
Ignoring dual agreement
❌ هذان القراران الذين غيرا السياسة مثيران للجدل.
Incorrect — the dual antecedent requires alladhāni.
✅ هذان القراران اللذان غيرا السياسة مثيران للجدل.
hādhāni l-qarārāni lladhāni ghayyarā s-siyāsata muthīrāni li-l-jadal.
These two decisions, which changed the policy, are controversial.
Key Takeaways
- Bare الذي is not a general sentential “which”; الأمر الذي gives it an explicit definite shell antecedent.
- The chosen shell noun controls gender, number, and dual case agreement.
- Use resumptive suffixes when the shell has an object, possessive, or prepositional role inside the clause.
- وهو ما is a headless-relative structure; مما is من + ما, often but not inherently resultative.
- These links are especially common in formal and academic prose; punctuation supports readability but does not replace syntax.
