ليه lēh is the ordinary mainstream Cairene word for “why.” It asks for a reason, explanation, or purpose, and a natural answer often begins with عشان “because / so that.” Unlike an English why question, an Egyptian ليه question needs no auxiliary equivalent to do, does, or did and no subject–verb inversion.
Position and intonation matter. Clause-final ليه is a dependable neutral pattern; initial ليه is also common, especially when the reason becomes the topic or the speaker sounds surprised, critical, or insistent. The question-intonation guide develops the melody behind that contrast.
Rule 1: Replace the Known Reason with ليه
Compare a statement containing a reason with the corresponding information question:
إنت لغيت الحجز عشان المعاد اتغير.
inta laghēt il-ḥagz ʿashān il-mīʿād itghayyar.
You canceled the reservation because the time changed.
إنت لغيت الحجز ليه؟
inta laghēt il-ḥagz lēh?
Why did you cancel the reservation?
The question retains إنت + لغيت + الحجز and replaces the reason phrase with ليه. English fronts why and adds did; Egyptian leaves the perfect verb fully inflected.
سلمى غيرت رأيها ليه بعد الاجتماع؟
Salma ghayyarit raʾyaha lēh baʿd il-igtimāʿ?
Why did Salma change her mind after the meeting?
المحل بيقفل بدري ليه يوم الحد؟
il-maḥall byiʾfil badri lēh yōm il-ḥadd?
Why does the shop close early on Sunday?
The verb form still contributes aspect: غيرت asks about a completed change; بيقفل asks about a schedule or recurring practice. ليه only opens the reason slot.
Rule 2: Final ليه Is Neutral; Initial ليه Frames the Reason
Final ليه commonly sounds like an ordinary request for information:
إنت مستني بره ليه؟
inta mistanni barra lēh?
Why are you waiting outside?
Initial ليه is fully grammatical, but it foregrounds the reason. With a wide pitch range it often conveys surprise or challenge.
ليه إنت مستني بره والباب مفتوح؟
lēh inta mistanni barra wi-l-bāb maftūḥ?
Why are you waiting outside when the door is open?
ليه عملت كده من غير ما تقوللي؟
lēh ʿamilt kida min ghēr ma tiʾulli?
Why did you do that without telling me?
The last question can be a genuine request, a reproach, or both. Syntax alone does not decide. A level, lower contour invites explanation; strong stress on ليه and كده makes the question more confrontational.
Do not turn this flexibility into a rule that all wh-words freely move. Object إيه and locative فين have strong in-situ patterns. ليه is an adjunct, so initial framing is especially natural.
Rule 3: A ليه Question Normally Presupposes the Situation
Asking why often treats the event or state as established. إنت سبت الشغل ليه؟ normally presupposes that the listener left the job.
إنت سبت الشغل ليه؟
inta sibt ish-shoghl lēh?
Why did you leave the job?
If that premise is uncertain, first ask whether it is true:
إنت سبت الشغل بجد؟ ولو سبته، سبت ليه؟
inta sibt ish-shoghl bi-gadd? wi-law sibto, sibt lēh?
Did you really leave the job? And if you did, why?
Negative questions carry their own presupposition: the expected event did not occur.
إنت ماجتش الاجتماع ليه؟
inta ma-gitsh il-igtimāʿ lēh?
Why didn't you come to the meeting?
The negative envelope remains joined around the verb. ليه does not change the choice between مش, مفيش, and verbal ما...ش.
Rule 4: Answer with عشان plus the Relevant Explanation
عشان can introduce a cause (“because”) or a purpose (“so that”). Context and the following clause make the relation clear.
إنت ماجتش ليه؟ ـ عشان كنت تعبان ومحتاج أنام.
inta ma-gitsh lēh? — ʿashān kunt taʿbān wi-meḥtāg ʾanām.
Why didn't you come? — Because I was tired and needed to sleep.
قفلت الإشعارات ليه؟ ـ عشان أعرف أركز في الشغل.
ʾafalt il-ʾishʿārāt lēh? — ʿashān ʾaʿraf ʾarakkiz fi sh-shoghl.
Why did you turn off the notifications? — So I could concentrate on work.
Natural answers need not repeat عشان when a noun phrase or short explanation is sufficient:
المشروع اتأخر ليه؟ ـ بسبب مشكلة في التوريد.
il-mashrūʿ itʾakhkhar lēh? — bisabab moshkila fi t-tawrīd.
Why was the project delayed? — Because of a supply problem.
بسبب is somewhat more explicit and common in professional explanations (neutral/formal-leaning). Everyday عشان is the conversational baseline (informal/neutral).
Rule 5: Proposed Reasons Turn Information into Confirmation
A bare ليه asks the listener to supply a reason. Once the speaker proposes one, the question becomes a confirmation check.
إنت لغيت الحجز عشان السعر، صح؟
inta laghēt il-ḥagz ʿashān is-siʿr, ṣaḥḥ?
You canceled the reservation because of the price, right?
لأ، لغيته عشان المعاد ماكانش مناسب.
laʾ, laghēto ʿashān il-mīʿād ma-kānsh monāseb.
No, I canceled it because the time wasn't suitable.
The first turn has confirmation bias: the speaker already offers السعر. The answer rejects that proposed cause but preserves the presupposition that the booking was canceled.
Rule 6: Embedded ليه Keeps Egyptian Order
After verbs of knowing, understanding, asking, or remembering, ليه stays inside its clause. Embedded status does not trigger English order.
مش فاهم هو رفض العرض ليه.
mish fāhim huwwa rafaḍ il-ʿarḍ lēh.
I don't understand why he rejected the offer.
اسأليها هي غيرت المعاد ليه.
isʾalīha hiyya ghayyarit il-mīʿād lēh.
Ask her why she changed the appointment. (to a woman)
Because ليه is a reason adjunct, it leaves no object or prepositional gap that requires a resumptive suffix. That contrasts with fronted مين plus معاه “who ... with him” or fronted إيه plus عنه “what ... about it.”
Register and Variation
ليه is the mainstream Cairo baseline (informal/neutral) and is also widespread beyond Cairo. Formal لماذا belongs to MSA writing, prepared speech, and deliberate formal code-switching (formal). Egyptian regional and community repertoires vary in vowel quality, preferred particles, and challenge contours (regional/social); this page does not flatten those systems into a single national pronunciation. Film and comedy may stretch ليه؟ dramatically (performance), making a challenge stronger than the same words in ordinary conversation.
Common Mistakes
1. Adding an invented equivalent of English “did”
❌ عمل إنت لغيت الحجز ليه؟
Incorrect — Egyptian does not insert a lexical do-support auxiliary.
✅ إنت لغيت الحجز ليه بعد ما أكدته؟
inta laghēt il-ḥagz lēh baʿd ma ʾakkadto?
Why did you cancel the reservation after confirming it?
2. Inverting subject and verb mechanically
❌ غيرت سلمى رأيها ليه؟
Mismatched as a neutral subject-first question — verb-first order would present the event, not reproduce English inversion.
✅ سلمى غيرت رأيها ليه فجأة؟
Salma ghayyarit raʾyaha lēh fagʾa?
Why did Salma suddenly change her mind?
3. Leaving عشان before the missing reason
❌ إنت غيرت المعاد عشان ليه؟
Incorrect — عشان introduces an actual reason, while ليه itself fills the missing-reason slot.
✅ إنت غيرت المعاد ليه بعد ما أكدته؟
inta ghayyart il-mīʿād lēh baʿd ma ʾakkadto?
Why did you change the appointment after confirming it?
4. Using formal لماذا as the casual default
❌ لماذا تأخرت دلوقتي؟
Register mismatch — لماذا and the formal verb form do not match ordinary Cairene دلوقتي.
✅ إنت اتأخرت ليه النهارده؟
inta itʾakhkhart lēh in-nahārda?
Why were you late today?
5. Adding هل to a ليه question
❌ هل إنت مشيت بدري ليه؟
Incorrect mixture — هل marks a formal polar question and does not belong in this everyday why-question.
✅ إنت مشيت بدري ليه قبل ما الاجتماع يخلص؟
inta mishēt badri lēh ʾabl ma l-igtimāʿ yikhlaṣ?
Why did you leave early before the meeting ended?
