A negative question asks whether a negative proposition is true: “Isn’t the office open?”, “Didn’t she call?”, or “Don’t you want a receipt?” Formal Modern Standard Arabic builds such questions by putting an interrogative marker before an already well-formed negative clause. It does not add English do, and it does not invert the subject and verb.
The hardest part for an English speaker is often the answer. Careful Arabic answers the proposition, not the positive wording that the English speaker may have in mind. بلى rejects the negation—“on the contrary, yes”—whereas نعم confirms it. Repeating the relevant clause is the clearest practice whenever the practical consequences matter.
For the affirmative baseline with the same interrogative particles, see Yes–No Questions with هل and أ.
Build the negative clause first
Begin with an ordinary negative statement, then add the question marker. هل is a separate word. Interrogative أَـ is a prefix and commonly combines with لم as ألم or with ليس as أليس.
لم تصل الحافلة في موعدها.
lam taṣili l-ḥāfilatu fī mawʿidihā.
The bus did not arrive on time.
ألم تصل الحافلة في موعدها؟
ʾa-lam taṣili l-ḥāfilatu fī mawʿidihā?
Didn't the bus arrive on time?
Nothing inside the clause has inverted. لم still governs the jussive تصلْ; the linking vowel heard before الحافلة merely eases pronunciation. The prefixed interrogative hamza adds a question, but it does not change the tense, agreement, or mood selected by لم.
The same no-inversion method works in a verb-first clause with an overt postverbal subject:
لم توقع المديرة العقد.
lam tuwaqqiʿi l-mudīratu l-ʿaqd.
The director did not sign the contract.
ألم توقع المديرة العقد؟
ʾa-lam tuwaqqiʿi l-mudīratu l-ʿaqda?
Didn't the director sign the contract? (Neutral verb-first question; no English-style inversion.)
The question changes the information request, not the grammatical relation between توقع and المديرة. The overt feminine singular subject remains after its feminine singular verb in the neutral question.
هل لا asks about a present or habitual negative
For present and habitual verbal negation, هل لا + indicative imperfect is transparent and productive (formal). It often conveys surprise, a request for confirmation, or a gentle challenge, depending on context and intonation.
هل لا تستخدم هذا التطبيق في العمل؟
hal lā tastakhdimu hādhā t-taṭbīqa fī l-ʿamali?
Don't you use this application at work? (Addressed to one man.)
هل لا تفضلين الجلوس قرب النافذة؟
hal lā tufaḍḍilīna l-julūsa qurba n-nāfidhati?
Don't you prefer sitting near the window? (Addressed to one woman.)
The masculine تستخدم and feminine تفضلين are ordinary forms selected by the addressee. هل and لا do not neutralize gender. The present negator لا leaves the indicative intact; it is not the prohibitive لا that governs a jussive command.
In contemporary edited prose, writers may prefer a positive neutral question when no prior expectation exists: هل تستخدم التطبيق؟ “Do you use the application?” The negative version normally suggests that the speaker expected the answer to be positive, has evidence to the contrary, or wants the listener to reconsider. That expectation is pragmatic rather than a different syntactic construction.
ألم asks about a denied past event
ألم consists of interrogative أَـ plus past negator لم. Because لم governs the jussive, weak verbs and the five verbs show their ordinary jussive morphology.
ألم ترسلي النسخة إلى المحرر؟
ʾa-lam tursilī n-nuskhata ʾilā l-muḥarriri?
Didn't you send the copy to the editor? (Addressed to one woman; the mood nūn is deleted.)
ألم يسع الفريق إلى حل وسط؟
ʾa-lam yasʿa l-farīqu ʾilā ḥallin wasaṭ?
Didn't the team seek a compromise? (Final weak letter deleted in the jussive.)
In ترسلي, the expected indicative form is ترسلين; لم deletes the mood nūn. In يسع, final ى of يسعى is deleted. The interrogative hamza contributes no mood government of its own.
أليس asks about a negative nominal predicate
For a present state, identity, classification, or location, use an inflected form of ليس. Its subject remains nominative, and a noun or adjective predicate is accusative.
أليس الموعد مناسبا للجميع؟
ʾa-laysa l-mawʿidu munāsiban li-l-jamīʿi?
Isn't the appointment suitable for everyone?
أليست البيانات متاحة على الموقع؟
ʾa-laysati l-bayānātu mutāḥatan ʿalā l-mawqiʿi?
Aren't the data available on the website? (Nonhuman plural with feminine-singular agreement.)
The feminine singular أليست agrees with the nonhuman plural البيانات. This is ordinary Arabic agreement, not a special question form. With a prepositional predicate, the preposition keeps its complement:
أليس المفتاح معك؟
ʾa-laysa l-miftāḥu maʿaka?
Don't you have the key with you? (Literally, isn't the key with you? Addressed to one man.)
The clitic ـك remains attached to مع. Arabic does not detach it or strand مع at the end to imitate English.
Answer the proposition: بلى versus نعم
After an affirmative question, نعم normally affirms and لا rejects. After a negative question, the polarity works differently:
| Answer | Effect on the negative question | Safe expansion |
|---|---|---|
| بلى | rejects the negation | بلى، وصل / بلى، هو جاهز |
| نعم | confirms the negation | نعم، لم يصل / نعم، ليس جاهزًا |
ألم تحجزي الموعد؟ بلى، حجزته صباحا.
ʾa-lam taḥjizī l-mawʿida? balā, ḥajaztuhu ṣabāḥan.
Didn't you book the appointment? Yes, I booked it this morning. (Addressed to one woman; بلى reverses the negation.)
ألم تحجزوا الموعد؟ نعم، لم نحجزه بعد.
ʾa-lam taḥjizū l-mawʿida? naʿam, lam naḥjizhu baʿd.
Didn't you book the appointment? That's right, we have not booked it yet. (نعم confirms the negative.)
أليس القطار متأخرا؟ بلى، لكنه سيصل خلال دقائق.
ʾa-laysa l-qiṭāru mutaʾakhkhiran? balā, lakinnahu sayaṣilu khilāla daqāʾiq.
Isn't the train late? Yes, but it will arrive within minutes.
The last English yes agrees with “the train is late,” so Arabic uses بلى to overturn “not late.” Bare نعم would formally confirm “it is not late.” Usage can be looser in spontaneous regional speech (regional), but a learner writing MSA should make the proposition explicit.
Intonation, expectation, and scope
The grammar marks the clause as a question, while intonation signals the speaker's stance. A rising contour may request genuine confirmation; a falling or emphatic contour may express disbelief, reproach, or a rhetorical expectation. Written Arabic uses ؟ in all of these questions, but punctuation alone does not tell the reader how strongly an answer is expected.
Negation also has scope. Compare asking whether an action failed to happen with correcting one constituent:
ألم ترسل التقرير إلى الإدارة؟ نعم، لم أرسله إلى الإدارة؛ بل أرسلته إلى المحاسب.
ʾa-lam tursili t-taqrīra ʾilā l-ʾidārati? naʿam, lam ʾursilhu ʾilā l-ʾidārati; bal ʾarsaltuhu ʾilā l-muḥāsib.
Didn't you send the report to management? That's right, I didn't send it to management; rather, I sent it to the accountant. (The destination is corrected.)
Here نعم confirms the full negative proposition “I did not send it to management,” while بل corrects the destination and makes clear that sending nevertheless occurred. A negative question does not mechanically place every following constituent under one undifferentiated negation; discourse and the expanded answer identify what is being challenged.
Common Mistakes
Adding do-support or reversing the clause like English
❌ ألم فعلت ترسل المديرة العقد؟
Incorrect—Arabic uses neither فعل as dummy ‘do’ nor English auxiliary inversion.
✅ ألم ترسل المديرة العقد إلى المستشار؟
ʾa-lam tursili l-mudīratu l-ʿaqda ʾilā l-mustashāri?
Didn't the director send the contract to the adviser?
Using a Latin question mark
❌ أليس الاجتماع غدا?
Incorrect typography—an Arabic question ends with ؟.
✅ أليس الاجتماع صباح غد؟
ʾa-laysa l-ijtimāʿu ṣabāḥa ghadin?
Isn't the meeting tomorrow morning?
Misreading inflected أيّ in a related content question
❌ أي تقرير لم تقرئي؟
ʾayyu taqrīrin lam taqraʾī
Incorrect reading—the requested report is the object, so أيّ is accusative ʾayya, not nominative ʾayyu.
✅ أي تقرير لم تقرئي بعد؟
ʾayya taqrīrin lam taqraʾī baʿdu?
Which report have you not read yet?
Stranding a preposition
❌ من لم تتحدث معه المديرة إلى؟
Incorrect—formal MSA does not leave إلى stranded; move it with من.
✅ إلى من لم ترسل المديرة الدعوة؟
ʾilā man lam tursili l-mudīratu d-daʿwata?
To whom did the director not send the invitation?
Answering a negative question with bare ambiguous نعم
❌ أليس الباب مقفلا؟ نعم.
Unsafe and ambiguous for an English speaker—نعم formally confirms the negative proposition, but the intended physical state remains unstated.
✅ أليس الباب مقفلا؟ بلى، هو مقفل بالمفتاح.
ʾa-laysa l-bābu muqfalan? balā, huwa muqfalun bi-l-miftāḥ.
Isn't the door locked? Yes, it is locked with the key.
Key Takeaways
- Form the negative clause first, then add هل or prefixed أَـ; never add English do-support.
- هل لا questions present or habitual negation, ألم combines with a jussive for past negation, and أليس questions a negative nominal predicate.
- The particles do not cancel ordinary word order, agreement, case, clitic attachment, or mood government.
- بلى rejects a negative proposition; نعم confirms it.
- Repeat the relevant clause after بلى or نعم whenever a bare answer could be misunderstood.
