Lebanese ممكنmomken presents a proposition or action as possible. With statement intonation it often means “maybe / it is possible that.” As a question addressed to someone, it can ask permission or make a polite request: ممكن فوت؟ “May I come in?”; ممكن تساعدني؟ “Could you help me?”
The particle does not conjugate. A following imperfect action is normally bare—without the ordinary b-marker—but still agrees with its actor. Context, person marking, and intonation tell the listener whether the speaker is assessing a possibility or asking someone to act.
Epistemic possibility
At the beginning of a declarative clause, ممكن weakens the speaker’s commitment: the proposition is a live possibility, not an established fact.
ممكن يتأخر الباص بسبب الزحمة.
momken yitʾakhkhar el-bāṣ b-sabab ez-zaḥme.
The bus might be delayed because of traffic. (informal epistemic possibility)
ممكن رنا تكون بعدها بالمكتب.
momken Rana tkūn baʿda bil-maktab.
Rana may still be at the office. (informal; overt subject)
ممكن يكون العنوان غلط.
momken ykūn el-ʿonwēn ghalaṭ.
The address might be wrong. (neutral possibility with يكون)
The following clause supplies the content under consideration. Unlike لازم in its inferential use, ممكن does not present the evidence as forcing a strong conclusion.
الضو شغال؛ ممكن يكون حدا جوا.
eḍ-ḍaww shaghghāl; momken ykūn ḥada zhuwwa.
The light is on; someone might be inside. (tentative inference)
الضو شغال؛ لازم يكون حدا جوا.
eḍ-ḍaww shaghghāl; lāzem ykūn ḥada zhuwwa.
The light is on; someone must be inside. (stronger inference)
This minimal pair contrasts stance: the visible light licenses a possibility with ممكن, while لازم presents the speaker as drawing the stronger conclusion.
A bare agreeing action
When ممكن directly licenses an action, the imperfect lacks ordinary بـ but retains agreement.
ممكن ارجع بعد الضهر.
momken irzhaʿ baʿd eḍ-ḍoher.
I may come back in the afternoon. (first-person bare action)
ممكن ترجعي بكرا إذا اليوم مشغولة.
momken tirzhaʿe bokra iza l-yōm mashghūle.
You can come back tomorrow if you're busy today. (permission/option to one woman)
ممكن يوصلوا قبلنا.
momken yūṣalo ʾabelna.
They might arrive before us. (third-person plural possibility)
“Bare” does not mean infinitive. ارجع is first person, ترجعي is feminine second person, and يوصلوا is third-person plural. Bare Imperfect Forms gives the full contrast.
Permission questions
With first-person action and rising question intonation, ممكن asks whether the speaker is allowed to act. English often uses may or can.
ممكن فوت؟
momken fūt?
May I come in? (polite everyday permission request)
ممكن استعمل الحمام لو سمحت؟
momken istaʿmel el-ḥammēm law samaḥt?
May I use the bathroom, please? (polite request)
ممكن ناخد صورة هون؟
momken nākhod ṣūra hōn?
May we take a photo here? (polite permission request)
The rising contour targets the addressee’s permission. With falling statement intonation, ممكن ناخد صورة هون can instead mean “It is possible for us to take a photo here.” Real conversation, not the particle alone, supplies the speech act.
Polite requests to the listener
With a second-person bare verb, ممكن...؟ asks the listener to perform an action. It softens the directive by presenting compliance as possible rather than issuing a bare command.
ممكن تعطيني كاسة مي؟
momken tiʿṭīne kēset mayy?
Could you give me a glass of water? (polite informal request)
ممكن تكتبي اسمك هون؟
momken tiktbe ismik hōn?
Could you write your name here? (polite request to one woman)
ممكن تبعتولنا الفاتورة عالإيميل؟
momken tibʿatūlna l-fātūra ʿal-īmēl?
Could you send us the invoice by email? (professional spoken; request to a group/business)
This construction is polite but not automatically deferential enough for every high-stakes setting. Tone, greetings, لو سمحت, and titles can add social distance. See Requests.
Elliptical requests
When the desired transaction is obvious, ممكن can introduce a noun phrase without an overt verb. Service contexts supply an understood “can I have / could you give me.”
ممكن قهوة بلا سكر؟
momken ʾahwe bla sokkar?
Could I have a coffee without sugar? (informal service request)
ممكن الحساب لو سمحت؟
momken el-ḥsēb law samaḥt?
Could I have the bill, please? (polite restaurant request)
No hidden Lebanese verb needs to be inserted in the analysis. The noun itself names the requested item, and the interaction makes the intended transfer clear.
Possibility about an earlier event
For a past possibility, ممكن يكون + perfect places the possible event before the current assessment.
ممكن يكون نسي المفتاح بالبيت.
momken ykūn nise l-miftēḥ bil-bēt.
He may have forgotten the key at home. (retrospective possibility)
ممكن يكونوا وصلوا قبل ما دقينا.
momken ykūno wiṣlo ʾabel ma daʾʾēna.
They may have arrived before we called. (plural retrospective possibility)
The particle remains invariant; يكون/يكونوا and the perfect verb carry agreement and temporal structure.
Negation and scope
مش ممكن + clause denies possibility: “impossible / cannot be.” ممكن ما + clause keeps possibility but puts negation inside it: “possibly not.”
مش ممكن يخلصوا كل هالشغل اليوم.
mish momken ykhallṣo kill hash-shoghol el-yōm.
It's impossible for them to finish all this work today. (possibility denied)
ممكن ما يخلصوا كل الشغل اليوم.
momken ma ykhallṣo kill esh-shoghol el-yōm.
They might not finish all the work today. (negative proposition remains possible)
ممكن ما تجي رنا، بس مش أكيد.
momken ma tzhe Rana, bass mish akīd.
Rana might not come, but it isn't certain. (informal uncertainty)
The word order makes the scope visible. English speakers often confuse may not in exactly the same way, so memorize the Lebanese contrast as complete frames.
Dialogue: changing an appointment
مرحبا، ممكن غير موعدي لبكرا؟
marḥaba, momken ghayyer mawʿde la-bokra?
Caller: Hello, may I change my appointment to tomorrow? (polite service request)
ممكن، بس أي وقت بناسبك؟
momken, bass ayya waʾet bnēsebak?
Receptionist: That's possible, but what time suits you?
ممكن يكون في موعد فاضي بعد الضهر؟
momken ykūn fī mawʿed fāḍe baʿd eḍ-ḍoher?
Caller: Might there be an available appointment in the afternoon?
إي، ممكن تجي عالأربعة.
ē, momken tzhe ʿal-arbaʿa.
Receptionist: Yes, you can come at four. (permission/available option)
Common Mistakes
Keeping the b-marker after ممكن
❌ ممكن بتساعدني بهالطلب؟
Incorrect for the intended request — ممكن licenses bare تساعدني.
✅ ممكن تساعدني بهالطلب؟
momken tsāʿedne b-haṭ-ṭalab?
Could you help me with this order?
Conjugating ممكن instead of the action
❌ ممكنة تروحي بكرا.
Incorrect — the modal particle stays invariant; feminine agreement belongs on تروحي.
✅ ممكن تروحي بكرا.
momken trūḥe bokra.
You can go tomorrow. (one female addressee)
Reversing negative scope
❌ مش ممكن يجي.
Wrong for the intended ‘he might not come’ — this says his coming is impossible.
✅ ممكن ما يجي.
momken ma yzhe.
He might not come.
Using a formal question shell in casual speech
❌ هل من الممكن أن تعطيني الحساب؟
Register mismatch — grammatical formal Arabic, but not ordinary urban Lebanese service speech.
✅ ممكن تعطيني الحساب لو سمحت؟
momken tiʿṭīne l-ḥsēb law samaḥt?
Could you give me the bill, please? (polite Lebanese)
Key Takeaways
Use invariant ممكن with a bare agreeing clause to mark possibility. Statement intonation favors epistemic “maybe,” while a rising question can request permission or action. Second-person agreement asks the listener to act; first-person agreement asks permission for the speaker. For past possibility, use ممكن يكون + perfect. Keep مش ممكن “impossible” distinct from ممكن ما “possibly not.”
