ابتدى / بيبتدي ibtada / biyibtidi is the mainstream Cairene workhorse for “begin, start.” It is historically related to بدأ and the root ب-د-ء, but its everyday Cairo paradigm behaves as final-weak Pattern VIII: unsuffixed perfect ابتدى ends in ى, suffixed ابتديت exposes ي and long ē, and the imperfect ends in i. Learn these stems as a unit rather than adding endings to the English gloss begin.
ابتدى can introduce a noun event or a following activity. When the complement is another verb, that activity is normally a person-marked bare imperfect: ابتديت أشتغل, not ابتديت بشتغل. The wider onset system is compared on verbs of beginning.
Complete practical paradigm
Third masculine ابتدى contrasts with first/second ابتديت and first plural ابتدينا. Third feminine is also written ابتديت, but is pronounced ibtadyit rather than first-person ibtadēt. Plural imperfect forms drop final i before ـوا.
| Person | Perfect | Bare imperfect | b-imperfect | ḥa-future |
|---|---|---|---|---|
| أنا | اِبْتَدِيتْ ibtadēt | أَبْتِدِي ʾabtidi | بَابْتِدِي babtidi | حَابْتِدِي ḥabtidi |
| إنت | اِبْتَدِيتْ ibtadēt | تِبْتِدِي tibtidi | بِتِبْتِدِي bitibtidi | حَتِبْتِدِي ḥatibtidi |
| إنتي | اِبْتَدِيتِي ibtadēti | تِبْتِدِي tibtidi | بِتِبْتِدِي bitibtidi | حَتِبْتِدِي ḥatibtidi |
| هو | اِبْتَدَى ibtada | يِبْتِدِي yibtidi | بِيِبْتِدِي biyibtidi | حَيِبْتِدِي ḥayibtidi |
| هي | اِبْتَدِيِتْ ibtadyit | تِبْتِدِي tibtidi | بِتِبْتِدِي bitibtidi | حَتِبْتِدِي ḥatibtidi |
| إحنا | اِبْتَدِينَا ibtadēna | نِبْتِدِي nibtidi | بِنِبْتِدِي binibtidi | حَنِبْتِدِي ḥanibtidi |
| إنتوا | اِبْتَدِيتُوا ibtadētu | تِبْتِدُوا tibtidu | بِتِبْتِدُوا bitibtidu | حَتِبْتِدُوا ḥatibtidu |
| هم | اِبْتَدُوا ibtadu | يِبْتِدُوا yibtidu | بِيِبْتِدُوا biyibtidu | حَيِبْتِدُوا ḥayibtidu |
The command is ابتدي ibtidi to one man or woman and ابتدوا ibtidu to a group. Negative commands are ماتبتديش and ماتبتدوش. The gender-neutral singular command follows from the final-weak stem; it is not missing feminine agreement.
ابتديت كورس جديد في تحليل البيانات.
ibtadēt kōrs gidīd fi taḥlīl il-bayānāt.
I started a new course in data analysis. (informal/professional)
الموسم بيبتدي في أكتوبر كل سنة.
il-mawsim biyibtidi fi ʾOktōbar koll sana.
The season begins in October every year. (habitual schedule)
ممكن نبتدي بعد ما الناس كلها توصل.
momkin nibtidi baʿd ma n-nās kollaha tiwṣal.
We can begin after everyone arrives.
Rule 1: an activity complement is bare
The onset verb carries person, viewpoint, and time. The following verb identifies the activity and appears in the bare imperfect, agreeing with the same understood doer.
ابتديت أتعلم ألماني عشان الشغل.
ibtadēt ʾatʿallim ʾalmāni ʿashān ish-shoghl.
I started learning German for work.
هي بتبتدي تراجع الطلبات الساعة تمانية.
hiyya bitibtidi tirāgiʿ iṭ-ṭalabāt is-sāʿa tamānya.
She starts reviewing the applications at eight.
حنبتدي نجهز القاعة بعد الغدا.
ḥanibtidi nigahhiz il-ʾāʿa baʿd il-ghada.
We'll start preparing the hall after lunch.
English uses an infinitive or gerund after start. Egyptian has no invariant infinitive here: first-person أتعلم, feminine تراجعي, and plural تجهزوا still mark the activity's subject.
Rule 2: noun complements can name a project, period, or task
ابتدى + noun can mean “started a course/job/task,” while an event noun can itself be the subject: الاجتماع ابتدى “the meeting began.” Word order helps identify the participants, but context and agreement matter too.
المدير ابتدى الاجتماع بسؤال قصير.
il-modīr ibtada l-igtimāʿ bi-suʾāl ʾoṣayyar.
The manager started the meeting with a short question.
الاجتماع ابتدى متأخر عشان الأوضة كانت مشغولة.
il-igtimāʿ ibtada mitʾakhkhar ʿashān il-ʾōḍa kānit mashghūla.
The meeting began late because the room was occupied.
With a pronominal task, the object attaches. Third masculine ابتداها opens final ى to alif before ـها; subject-suffixed ابتديتها keeps the visible ي.
ابتديتها لوحدي، وبعدين زميلي ساعدني.
ibtadētha liwaḥdi, wi-baʿdēn zamīli sāʿidni.
I started it on my own, then my colleague helped me. (a feminine task/project)
Rule 3: distinguish ابتدى from بدأ by register and speaker choice
بدأ / بيبدأ badaʾ / biyibdaʾ is fully legitimate and widely understood. It is especially frequent in formal writing, news, education, and deliberate educated speech (formal/educated). ابتدى / بيبتدي is the consistent everyday Cairo production baseline (informal/neutral). Many speakers code-switch between them; neither is an “incorrect version” of the other.
المؤتمر سيبدأ في تمام العاشرة.
il-muʾtamar sayabdaʾ fi tamām il-ʿāshira.
The conference will begin at exactly ten. (formal announcement/MSA-oriented)
الحفلة حتبتدي الساعة عشرة، بس إحنا حنوصل بدري.
il-ḥafla ḥatibtidi s-sāʿa ʿashara, bass iḥna ḥaniwṣal badri.
The party will start at ten, but we'll arrive early. (informal Cairo)
The first example is intentionally formal rather than marked incorrect. Avoid mixing formal future سـ and case-like endings into an otherwise ordinary Cairene sentence by accident.
Rule 4: negation targets the onset
مابتديتش أكتب says the writing never began. The negative circumfix stays on ابتدى, not on the bare activity. A direct-object suffix remains inside it.
مابتديتش أحضر للعرض لسه.
ma-btadētish ʾaḥaḍḍar lil-ʿarḍ lissa.
I haven't started preparing for the presentation yet.
المهمة دي مابتديتهاش عشان البيانات ناقصة.
il-mohimma di ma-btadēthāsh ʿashān il-bayānāt nāʾṣa.
I haven't started this task because the data is incomplete.
Participles and lexical limits
مبتدي / مبتدية / مبتديين can describe someone beginning an activity and is lexicalized as “beginner.” It is not an all-purpose progressive replacement for بيبتدي. For an event that is just starting, finite بيبتدي or لسه بيبتدي is normally clearer.
أنا لسه مبتدي في التصوير ومحتاج أتدرب أكتر.
ʾana lissa mobtidi fit-taṣwīr wi-moḥtāg ʾatdarrab ʾaktar.
I'm still a beginner in photography and need more practice.
A short dialogue
أ: نبتدي الاجتماع ولا نستنى سارة؟
A: nibtidi l-igtimāʿ walla nistanna Sāra?
A: Shall we start the meeting or wait for Sara?
ب: نستنى خمس دقايق، وبعدها نبتدي من غيرها.
B: nistanna khams daʾāyiʾ, wi-baʿdaha nibtidi min ghērha.
B: Let's wait five minutes, then start without her.
Register and variation
The page teaches mainstream urban Cairo. Spelling varies between ابتدى and hamza-marked إبتدى in informal media; this guide keeps ابتدى. Alexandria, the Delta, Upper Egypt, Bedouin-associated communities, and different age or class networks vary in vowel quality and the balance between ابتدى and بدأ (regional/social). Formal announcements and news favor بدأ or MSA syntax (formal/media); comic performance may exaggerate formal بدأ inside casual speech (performance).
Common Mistakes
1. Keeping final ى before a suffix.
❌ أنا ابتدىت المشروع امبارح.
Incorrect house spelling and stem—the suffixed perfect is ابتديت.
✅ أنا ابتديت المشروع امبارح بعد الاجتماع.
ʾana ibtadēt il-mashrūʿ imbāriḥ baʿd il-igtimāʿ.
I started the project yesterday after the meeting.
2. Putting بـ on the activity complement.
❌ هو بيبتدي بيشتغل الساعة سبعة.
Incorrect phase-verb chain—the selected activity is bare.
✅ هو بيبتدي يشتغل الساعة سبعة في أيام الصيف.
huwwa biyibtidi yishtighal is-sāʿa sabʿa fi ʾayyām iṣ-ṣēf.
He starts work at seven on summer days.
3. Separating circumfixal negation.
❌ ما ابتديت أراجع ش.
Incorrect orthography and scope—ما...ش wraps the onset verb as one word.
✅ مابتديتش أراجع الحسابات لسه.
ma-btadētish ʾarāgiʿ il-ḥisābāt lissa.
I haven't started reviewing the accounts yet.
4. Importing an MSA citation form into casual Cairo.
❌ سوف أبدأ أعمل دلوقتي.
Register mixture for the intended casual sentence—formal سوف أبدأ does not fit ordinary Cairo دلوقتي.
✅ حبتدي أشتغل دلوقتي وأكلمك لما أخلص.
ḥabtidi ʾashtaghal dilwaʾti wi-ʾakallimak lamma ʾakhallaṣ.
I'll start working now and call you when I finish.
