An indirect question places an unresolved question inside a larger clause: “I do not know whether the train has left,” “She asked where the office was,” or “Tell me which version you chose.” Formal Modern Standard Arabic embeds هل or ما إذا for yes–no alternatives and keeps a content interrogative such as أين، متى، من، أيّ for the missing constituent.
Unlike English, Arabic does not switch between “Where is the office?” and “Do you know where the office is?” by moving an auxiliary. There was no English-style inversion in the direct Arabic question to undo. The embedded clause keeps ordinary Arabic order, and its tense is chosen for the actual time relation rather than being mechanically shifted backward after a past reporting verb.
The direct clause patterns embedded here are introduced on Yes–No Questions with هل and أ.
What makes a question indirect?
The larger or matrix clause introduces a mental or speech act: لا أعرف “I do not know,” سأل “he asked,” تحققت “she checked,” أخبرني “tell me,” or أتساءل “I wonder.” The following clause denotes the information that is unknown or requested.
أين يقع المكتب الجديد؟
ʾayna yaqaʿu l-maktabu l-jadīdu?
Where is the new office located? (Direct question.)
لا أعرف أين يقع المكتب الجديد.
lā ʾaʿrifu ʾayna yaqaʿu l-maktabu l-jadīd.
I do not know where the new office is located. (Indirect question; ordinary verb–subject order.)
The embedded أين remains a locative predicate or adjunct, and the answer would supply a place. The clause يقع المكتب is unchanged; Arabic adds no form of do and performs no auxiliary inversion.
The punctuation belongs to the whole sentence. A declarative matrix clause ends with a period even though it contains an unresolved question. If the matrix itself asks a question, it ends with ؟:
هل تعرف أين يقع المدخل الخلفي؟
hal taʿrifu ʾayna yaqaʿu l-madkhalu l-khalfiyyu?
Do you know where the rear entrance is?
Here هل marks the outer yes–no question. أين introduces the inner content question. One final Arabic question mark closes the complete sentence.
Embedded yes–no questions with هل
After verbs of knowing, asking, checking, or uncertainty, هل can introduce an embedded yes–no question (formal). It does not acquire case and does not govern the mood of the following verb.
سألني المدير هل انتهيت من المراجعة.
saʾalanī l-mudīru hali ntahaytu mina l-murājaʿa(h).
The director asked me whether I had finished the review.
تحققي هل يعمل الرابط عندك.
taḥaqqaqī hal yaʿmalu r-rābiṭu ʿindaki.
Check whether the link works for you. (Addressed to one woman.)
أخبرني هل ستشارك في الاجتماع.
ʾakhbirnī hal satushāriku fī l-ijtimāʿ.
Tell me whether you will participate in the meeting. (Addressed to one man.)
The masculine ستشارك and feminine imperative تحققي belong to their respective clauses. The English translation may use whether rather than if to avoid confusion with a condition; Arabic هل clearly marks an interrogative complement in these examples.
In polished prose, writers sometimes introduce the embedded question with عما إذا or restructure the sentence, especially when the attachment of هل could be unclear. There is no single mandatory frame after every matrix verb; valency and style matter.
ما إذا makes “whether” explicit
The sequence ما إذا is a common formal way to package a yes–no alternative, especially after لا أعرف، أتساءل، تحقق من، يعتمد على and in administrative or academic prose (formal/academic). With a nominal or temporally layered proposition, it frequently precedes كان.
لا نعرف ما إذا كان القطار قد غادر.
lā naʿrifu mā ʾidhā kāna l-qiṭāru qad ghādar.
We do not know whether the train has left.
تحققت من أن الملف موجود، لكنني لم أتحقق مما إذا كان محدثا.
taḥaqqaqtu min ʾanna l-malaffa mawjūdun, lakinnanī lam ʾataḥaqqaq mim-mā ʾidhā kāna muḥaddathan.
I verified that the file exists, but I did not verify whether it was up to date.
The second example contrasts a fact complement أن الملف موجود with an unresolved alternative ما إذا كان محدثا. English if can introduce either a condition or an embedded yes–no question; formal Arabic ما إذا is especially useful when “whether” must be unmistakable.
To state both possibilities overtly, add أم لا:
سيقرر الفريق ما إذا كان سيطلق الخدمة هذا الشهر أم لا.
sayuqarriru l-farīqu mā ʾidhā kāna sayuṭliqu l-khidmata hādhā sh-shahra ʾam lā.
The team will decide whether or not to launch the service this month.
أم لا closes the polarity alternatives. It does not turn the entire matrix statement into a direct question, so the sentence ends with a period.
Embedded content questions retain a real role
A wh-expression still occupies the subject, object, predicate, genitive, or adverbial slot that the answer will fill. Embedding does not make every interrogative indeclinable or nominative.
سألتني ليلى متى يبدأ التسجيل.
saʾalatnī laylā matā yabdaʾu t-tasjīl.
Layla asked me when registration begins.
أخبريني أي نسخة اخترت.
ʾakhbirīnī ʾayya nuskhatini khtarti.
Tell me which version you chose. (Addressed to one woman; accusative أيَّ as object.)
لم يوضح التقرير من اتخذ القرار.
lam yuwaḍḍiḥi t-taqrīru mani ttakhadha l-qarār.
The report did not clarify who made the decision. (من is the embedded subject.)
In أي نسخة اخترت, the whole choice phrase is the object of اخترت, so careful connected reading has accusative أيَّ and genitive نسخةٍ. In من اتخذ القرار, من itself supplies the embedded subject. Fronting does not erase those functions.
Prepositions and clitics stay with the interrogative relation
Formal Arabic normally fronts a preposition with its question word, even inside an indirect question. Expanded resumptive structures keep the preposition plus a pronoun inside the relative clause.
لا أتذكر مع من تحدثت بعد الجلسة.
lā ʾatadhakkaru maʿa man taḥaddathtu baʿda l-jalsa(h).
I do not remember whom I spoke with after the session.
أخبريني بأي خطة ستعملين.
ʾakhbirīnī bi-ʾayyi khuṭṭatin sataʿmalīna.
Tell me which plan you will work with. (Addressed to one woman; genitive أيِّ after بـ.)
سألت عن الموضوع الذي تحدثوا عنه في الاجتماع.
saʾaltu ʿani l-mawḍūʿi lladhī taḥaddathū ʿanhu fī l-ijtimāʿ.
I asked about the subject that they had discussed in the meeting. (Resumptive عنه.)
The last sentence is not itself an interrogative complement, but it demonstrates the resumptive alternative that learners often need in heavier structures. ـه attached to عن preserves the relation required by تحدث عن.
Arabic does not apply automatic backshift
English commonly shifts present to past after a past reporting verb: direct “Where does she live?” becomes “He asked where she lived.” Arabic instead chooses tense from the intended temporal viewpoint. If the state still holds, the imperfect can remain imperfect after a past matrix verb.
سألني سامر أين أسكن الآن.
saʾalanī sāmirun ʾayna ʾaskunu l-ʾāna.
Samer asked me where I live now. (No mechanical backshift; the residence is current.)
سألتني المديرة متى سأرسل النسخة النهائية.
saʾalatnī l-mudīratu matā saʾursilu n-nuskhata n-nihāʾiyya(h).
The director asked me when I would send the final copy. (Arabic keeps the future relative to the reported question.)
سأل المحقق أين كنت ليلة الحادث.
saʾala l-muḥaqqiqu ʾayna kuntu laylata l-ḥādith.
The investigator asked where I had been on the night of the incident. (Past time is selected because the situation is past.)
Arabic can of course use كان when the embedded state is genuinely past. The rule is not “never backshift”; it is “do not backshift merely because the matrix verb is past.” Choose أسكن، كنت، سأرسل according to when the embedded situation holds.
Supplying or reporting the answer
An embedded question denotes a missing proposition or constituent. When it is asked aloud as the complement of an imperative or question, the response supplies that information:
أخبرني متى ستغادر. بعد انتهاء الجلسة.
ʾakhbirnī matā satughādiru. baʿda ntihāʾi l-jalsa(h).
Tell me when you will leave. After the session ends.
هل تعرفين إلى من أرسل الطلب؟ إلى قسم الموارد البشرية.
hal taʿrifīna ʾilā man ʾursilu ṭ-ṭalaba? ʾilā qismi l-mawāridi l-bashariyya(h).
Do you know whom I should send the application to? To the human resources department. (Addressed to one woman.)
The short answers preserve the requested time or destination. A bare نعم can answer only the outer هل تعرفين...؟—it cannot supply the destination.
Common Mistakes
Importing English do-support or embedded inversion
❌ لا أعرف أين يفعل المدير يعمل.
Incorrect—Arabic uses no dummy ‘do,’ and the embedded clause keeps ordinary verbal syntax.
✅ لا أعرف أين يعمل المدير هذا الأسبوع.
lā ʾaʿrifu ʾayna yaʿmalu l-mudīru hādhā l-ʾusbūʿ.
I do not know where the director is working this week.
Putting a question mark after a declarative matrix clause
❌ لا أدري هل وصل البريد?
Incorrect punctuation—the whole sentence is declarative and should not end with a question mark; the mark shown is also Latin.
✅ لا أدري هل وصل البريد بعد.
lā ʾadrī hal waṣala l-barīdu baʿd.
I do not know whether the mail has arrived yet.
Treating fronted أيّ as automatically nominative
❌ أخبرني أي تقرير قرأت.
ʾakhbirnī ʾayyu taqrīrin qaraʾta
Incorrect reading—the choice phrase is the object of قرأت, so أيّ is accusative ʾayya.
✅ أخبرني أي تقرير قرأت أولا.
ʾakhbirnī ʾayya taqrīrin qaraʾta ʾawwalan.
Tell me which report you read first.
Stranding a preposition inside the embedded question
❌ لا أتذكر من أرسلت الرسالة إلى.
Incorrect in neutral formal MSA—front إلى with من.
✅ لا أتذكر إلى من أرسلت الرسالة السرية.
lā ʾatadhakkaru ʾilā man ʾarsaltu r-risālata s-sirriyya(h).
I do not remember whom I sent the confidential message to.
Giving ambiguous نعم after a negative embedded proposition
❌ سألني: ألم يصل العقد؟ فقلت: نعم.
Ambiguous—the report does not reveal whether نعم confirmed ‘it did not arrive’ or was intended as English-style ‘yes, it arrived.’
✅ سألني: ألم يصل العقد؟ فقلت: بلى، وصل صباحا.
saʾalanī: ʾa-lam yaṣili l-ʿaqdu? fa-qultu: balā, waṣala ṣabāḥan.
He asked me, ‘Didn't the contract arrive?’ and I said, ‘On the contrary, it arrived in the morning.’
Key Takeaways
- Use embedded هل or formal ما إذا for unresolved yes–no propositions.
- Keep من، أين، متى، كيف، أيّ in the embedded clause when they request a constituent.
- Arabic has neither English do-support nor an auxiliary inversion to undo in indirect questions.
- Front required prepositions with the interrogative, and inflect أيّ for its real syntactic role.
- Do not backshift mechanically after a past reporting verb; choose tense from the event's actual time.
- Punctuate the whole matrix sentence, not the embedded question in isolation.
