Egyptian لما locates one situation at the time of another and often corresponds to English when. وقت ما literally frames “the time that” and is especially useful for “whenever,” “at whatever time,” or an explicitly chosen time. They overlap, but aspect and discourse decide whether the time is a single past occasion, a regular occasion, or a future trigger.
The time clause may come first or second. It carries its own subject and predicate, but a future time clause normally uses a bare imperfect rather than repeating future حـ. The contrast between bounded and background past forms is developed in expressing past time.
Rule 1: past لما commonly links bounded perfect events
When both events are completed, the perfect in each clause gives a natural sequence. لما identifies the first clause as the temporal landmark; it does not itself mean “after.”
لما وصلت المكتب، لقيت الباب مقفول
lamma wiṣilt il-maktab, laʾet il-bāb maʾfūl
When I reached the office, I found the door locked.
كلمت منى لما الاجتماع خلص
kallimt Mona lamma l-igtimāʿ khiliṣ
I called Mona when the meeting ended.
لما النور رجع، شغلنا التكييف
lamma n-nūr rigiʿ, shaghghalna t-takyīf
When the power came back, we turned on the air conditioning.
The first and third naturally suggest that the main event followed the time-clause event. If strict “before” or “after” ordering matters, Egyptian has more explicit connectors; لما primarily establishes temporal coincidence or a transition point.
Rule 2: background activity pairs with a bounded event
For “when X happened, Y was in progress,” use كان + b-imperfect for the ongoing background. Either clause can contain the background, depending on what the speaker foregrounds.
لما دخلت القاعة، الناس كانوا بيتكلموا
lamma dakhalt il-ʾāʿa, in-nās kānu biyitkallimu
When I entered the room, people were talking.
كنت براجع الإيميل لما المدير اتصل
kont barāgiʿ il-ʾimīl lamma l-mudīr ittaṣal
I was checking my email when the manager called.
لما وصلنا المحطة، القطر كان بيتحرك
lamma wiṣilna l-maḥaṭṭa, il-ʾaṭr kān biyitḥarrak
When we reached the station, the train was moving.
Using two perfects in the last example would present the train’s movement as a bounded event rather than the scene already unfolding.
Rule 3: future لما takes a bare imperfect
In a future frame, the لما clause normally has a bare imperfect. The main clause can carry حـ, an imperative, or another expression of projected action.
لما أوصل البيت، حابعتلك رسالة
lamma ʾoṣal il-bet, ḥabʿatlak risāla
When I get home, I’ll send you a message.
لما تخلص الشغل كلمني
lamma tikhlaṣ ish-shughl kallimni
Call me when you finish work. (to one man)
حنبدأ الأكل لما باقي الضيوف يوصلوا
ḥanibdaʾ il-ʾakl lamma bāʾi ḍ-ḍuyūf yoṣalu
We’ll start eating when the rest of the guests arrive.
The future meaning of أوصل، تخلص، يوصلوا comes from the time relation and main clause, not from an embedded حـ. This resembles English present morphology after when, but the Egyptian form is specifically the bare imperfect, not the ordinary independent b-imperfect.
Rule 4: habitual لما uses the b-imperfect
When both situations recur, the b-imperfect presents each as a habit or regular process. Time expressions such as كل مرة، عادة reinforce the reading.
لما بروح وسط البلد بركب المترو
lamma barūḥ wasaṭ il-balad barkab il-mitro
When I go downtown, I take the metro.
كل مرة بتكلمه بيطلب وقت أكتر
koll marra bitkallimo biyiṭlub waʾt ʾaktar
Every time she calls him, he asks for more time.
الشارع بيهدى لما المحلات بتقفل
ish-shāriʿ biyihda lamma l-maḥallāt bitiʾfil
The street gets quiet when the shops close.
The second sentence has different subjects encoded by feminine بتكلمه and masculine بيطلب. The third has a nonhuman plural subject المحلات with feminine-singular verbal agreement in the mainstream baseline.
Rule 5: وقت ما highlights free choice or repeated availability
وقت ما is natural when the exact time is open, chosen by someone, or repeats whenever a condition holds. A bare imperfect often follows in these nonasserted free-choice environments.
كلمني وقت ما تفضى
kallimni waʾt ma tifḍa
Call me whenever you are free. (to one man)
تعالى وقت ما يناسبك
taʿāla waʾt ma yināsibak
Come whenever it suits you. (to one man)
وقت ما بنحتاج مساعدة، جارتنا بتقف جنبنا
waʾt ma biniḥtāg musāʿada, gāritna bitiʾaf ganbina
Whenever we need help, our neighbor stands by us.
In the first two, the listener can choose the occasion, so the embedded verb is bare. The third describes a recurring real pattern, so both clauses use the b-imperfect.
لما تفضى كلمني can also mean “call me when you are free.” وقت ما تفضى makes the openness of the time especially salient rather than naming one expected trigger.
Rule 6: subjects and negation stay local
Omit a repeated subject when verb marking and context make it clear. State a changed subject when needed. Negative ما...ش remains one word inside the time clause.
لما ماتلاقيش تاكسي، اطلب عربية بالتطبيق
lamma ma-tilāʾīsh tāksi, uṭlub ʿarabiyya bi-t-taṭbīʾ
When you cannot find a taxi, order a car through the app. (to one man)
وقت ما مايبقاش عندنا شغل بنقفل بدري
waʾt ma ma-yibʾāsh ʿandina shughl biniʾfil badri
Whenever we have no work, we close early.
لما منى توصل، خليها تكلمني
lamma Mona toṣal, khallīha tikallimni
When Mona arrives, have her call me.
The full subject منى blocks a same-subject interpretation. In the negative examples, لما / وقت ما remain outside the verbal negative complex.
Clause order and punctuation
A fronted time clause establishes the frame and is commonly followed by Arabic comma ، in edited writing. A postposed time clause adds the timing after the main assertion. Neither order changes the connector’s basic grammar.
لما خلصنا الحسابات، بعتنا التقرير للمدير
lamma khallaṣna l-ḥisābāt, baʿatna t-taʾrīr li-l-mudīr
When we finished the accounts, we sent the report to the manager.
بعتنا التقرير للمدير لما خلصنا مراجعته
baʿatna t-taʾrīr li-l-mudīr lamma khallaṣna murāgaʿto
We sent the report to the manager when we finished reviewing it.
The first foregrounds the completed review as the narrative frame. The second foregrounds the sending and supplies its time afterward.
A brief narrative
لما خرجنا من السينما، كانت الدنيا بتمطر
lamma kharagna min is-sīnima, kānit id-dunya bitimṭar
When we came out of the cinema, it was raining.
استنينا تحت السقيفة لحد ما المطر خف
istannena taḥt is-saʾīfa laḥadd ma l-maṭar khaff
We waited under the awning until the rain eased.
وقت ما لقينا تاكسي فاضي، ركبنا بسرعة
waʾt ma laʾena tāksi fāḍi, rakibna bi-surʿa
When we found a free taxi, we got in quickly.
ولما وصلنا البيت، المطر كان وقف
wi-lamma wiṣilna l-bet, il-maṭar kān wiʾif
And when we got home, the rain had stopped.
The story contrasts an ongoing background, a bounded change, the occasion when transport became available, and a state completed before arrival. Connector choice and aspect jointly build the timeline.
Register and variation
لما and وقت ما are central to mainstream Cairo speech (informal/neutral). عندما، حينما، وقتما are common in MSA-oriented writing and prepared speech (formal). They can occur in educated code-switching, but replacing every casual لما with عندما changes register rather than merely spelling.
Alexandrian, Delta, Upper Egyptian, Bedouin, class, age, and community varieties differ in vowels and preferred temporal particles (regional/social). Narrative performance may repeat ولما... ولما... for suspense (performance language). That rhetorical pattern is not required in neutral exposition.
Common Mistakes
1. Repeating future حـ inside the لما clause.
❌ لما حاوصل البيت، حاكلمك
Incorrect in the mainstream future-time pattern—the لما clause takes a bare imperfect.
✅ لما أوصل البيت، حاكلمك قبل العشا
lamma ʾoṣal il-bet, ḥakallimak ʾabl il-ʿasha
When I get home, I’ll call you before dinner.
2. Using a perfect inside an intended habit.
❌ كل مرة رحت البنك باخد رقم
Incorrect for the intended recurring present routine—the time-clause verb should be habitual.
✅ كل مرة بروح البنك باخد رقم وأستنى دوري
koll marra barūḥ il-bank bākhud raʾam wi-ʾastanna dori
Every time I go to the bank, I take a number and wait my turn.
3. Hiding a subject change.
❌ لما تخلص الشغل حنتحرك
Incorrect for the intended meaning ‘when Mona finishes’—the changed subject is missing.
✅ لما منى تخلص الشغل حنتحرك كلنا
lamma Mona tikhlaṣ ish-shughl ḥanitḥarrak kullina
When Mona finishes work, we’ll all leave.
4. Importing formal عندما into casual dialogue without a register purpose.
❌ عندما أصل إلى البيت سوف أتصل بك
Grammatical formal MSA, but mismatched with an ordinary Cairo phone conversation.
✅ لما أوصل حابعتلك على الواتساب
lamma ʾoṣal ḥabʿatlak ʿala l-Wātsāb
When I arrive, I’ll message you on WhatsApp.
