The common religious verb دعا / بيدعي daʿa / biyidʿi means “pray, make a supplication,” often with ربنا “God” or a complement introduced by لـ or على. Its citation spelling ends in ا, reflecting a historical final و, but its Cairene imperfect ends in -i and its suffixed perfect uses -ē-: دعيت daʿēt. That surface alternation is why the whole perfect–imperfect pair must be learned.
The same written verb has more formal senses such as “call, invite, advocate.” In everyday Cairo, inviting a person socially is more often عزم / بيعزم (informal). This page uses the ordinary spoken religious sense and labels formal extensions rather than blending them.

The practical perfect paradigm
The perfect has three useful surface shapes: unsuffixed دعا daʿa, long-vowel دعيـ daʿē- before consonant-initial person endings, and short دعـ daʿ- before the vowel-initial third-person endings.
| Person | Perfect | Reading |
|---|---|---|
| أنا | دعيت | daʿēt |
| إنت | دعيت | daʿēt |
| إنتي | دعيتي | daʿēti |
| هو | دعا | daʿa |
| هي | دعت | daʿit |
| إحنا | دعينا | daʿēna |
| إنتوا | دعيتوا | daʿētu |
| هم | دعوا | daʿu |
دعيت ربنا يطمن قلبي قبل النتيجة.
daʿēt rabbena yiṭammin ʾalbi ʾabl in-natīga.
I prayed to God to put my heart at ease before the result.
هم دعوا لكل الناس اللي ساعدوهم.
humma daʿu li-koll in-nās illi sāʿadūhum.
They prayed for everyone who helped them.
Rule 1: the imperfect is final -i
The bare imperfect uses ادعي، تدعي، يدعي، ندعي. Add بـ for a neutral current or habitual main clause and حـ for a projected event. The masculine singular and feminine singular second-person forms sound alike here; plural -وا replaces final -i.
| Person | B-imperfect | Future |
|---|---|---|
| أنا | بدعي badʿi | حدعي ḥa-dʿi |
| إنت / إنتي | بتدعي bitidʿi | حتدعي ḥa-tidʿi |
| هو | بيدعي biyidʿi | حيدعي ḥa-yidʿi |
| هي | بتدعي bitidʿi | حتدعي ḥa-tidʿi |
| إحنا | بندعي binidʿi | حندعي ḥa-nidʿi |
| هم | بيدعوا biyidʿu | حيدعوا ḥa-yidʿu |
Time-context minimal pair
دعيت ربنا امبارح قبل الامتحان.
daʿēt rabbena imbāriḥ ʾabl il-imtiḥān.
I prayed to God yesterday before the exam.
بدعي ربنا كل يوم يوفقها.
badʿi rabbena koll yōm yiwaffaʾha.
I pray every day that God grants her success.
لازم تدعي وتاخد بالأسباب.
lāzim tidʿi wi-tākhud bil-ʾasbāb.
You have to pray and take practical steps.
The bare تدعي follows لازم. It is not an indicative missing بـ, and it does not take an MSA subjunctive or jussive ending.
Rule 2: learn دعا له and دعا عليه as different frames
دعا لحد means “pray for someone”; دعا على حد means “pray against someone, call down harm on someone.” The preposition changes the relationship, and its pronoun suffix stays attached to it.
دعت لأخوها قبل العملية.
daʿit li-ʾakhūha ʾabl il-ʿamaliyya.
She prayed for her brother before the operation.
ماتدعيش عليه، يمكن ماكانش قاصد.
ma-tidʿīsh ʿalēh, yimkin ma-kānsh ʾāṣid.
Don’t pray against him; maybe he didn’t mean it.
أنا بدعيلها تقوم بالسلامة.
ʾana badʿīlha tʾūm bis-salāma.
I’m praying that she recovers safely.
In بدعيلها, final -i is lengthened before the attached لها sequence. The writing stays one verb word plus its bound recipient material; do not split the pronoun off as an English object.
Rule 3: negation surrounds the suffixed stem
Perfect negation uses ما...ش around the perfect form; b-imperfect negation retains بـ. A prepositional pronoun remains inside the negative word when it has fused with the verb.
Positive-to-negative pair
دعيتله بعد الفجر.
daʿētlu baʿd il-fagr.
I prayed for him after dawn.
مادعيتلوش امبارح.
ma-daʿētlūsh imbāriḥ.
I didn’t pray for him yesterday.
هو مابيدعيش على حد.
huwwa ma-biyidʿīsh ʿala ḥadd.
He doesn’t pray against anyone.
Rule 4: separate everyday prayer from formal senses
دعا ربنا and دعا لحد are normal in informal religious talk. The sense “invite” in دعا الضيوف للحفل and institutional phrases such as “called for reform” are more characteristic of MSA-influenced news or formal speech (formal). An Egyptian speaker may code-switch into them deliberately. Everyday social “invite” is commonly عزم.
عزمنا الجيران على العشا.
ʿazamna l-gīrān ʿala l-ʿasha.
We invited the neighbors to dinner. (ordinary conversational choice)
Regional, community, and performance styles can preserve other pronunciations or favor more shared-Arabic vocabulary. Those are register choices, not defective versions of Cairene.
A two-turn Cairene dialogue
دعيتلي قبل المقابلة؟
daʿētli ʾabl il-moʾābla?
Did you pray for me before the interview?
أكيد، ولسه بدعيلك النتيجة تطلع حلوة.
ʾakīd, wi-lissa badʿīlak in-natīga tiṭlaʿ ḥilwa.
Of course, and I’m still praying that you get a good result.
Common Mistakes
Importing the MSA perfect suffix stem
❌ أنا دعوت ربنا امبارح.
Incorrect for the Cairene production baseline—the ordinary suffixed perfect is دعيت.
✅ أنا دعيت ربنا امبارح.
ʾana daʿēt rabbena imbāriḥ.
I prayed to God yesterday.
Omitting b- from a habitual main clause
❌ هو يدعي قبل كل امتحان.
Incorrect as a neutral Cairene habit—the main verb needs b-.
✅ هو بيدعي قبل كل امتحان.
huwwa biyidʿi ʾabl koll imtiḥān.
He prays before every exam.
Using b- after لازم
❌ لازم بتدعي وتاخد بالأسباب.
Incorrect for the intended obligation—لازم licenses the bare imperfect.
✅ لازم تدعي وتاخد بالأسباب.
lāzim tidʿi wi-tākhud bil-ʾasbāb.
You must pray and take practical steps.
Separating the attached recipient
❌ بدعي لها تقوم بالسلامة.
Incorrect for the intended bound Cairene pronunciation—the recipient sequence joins the verb.
✅ بدعيلها تقوم بالسلامة.
badʿīlha tʾūm bis-salāma.
I pray that she recovers safely.
Separating the future marker
❌ أنا ح ادعيلك بكرة.
Incorrect spelling—the Egyptian future marker joins the verb.
✅ أنا حدعيلك بكرة.
ʾana ḥa-dʿīlak bokra.
I’ll pray for you tomorrow.
Treating formal “invite” as the only everyday choice
❌ لازم أستخدم دعا لكل عزومة عادية.
Incorrect—formal دعا and conversational عزم differ in register and lexical use.
✅ عزمت صحابي على العشا.
ʿazamt ṣoḥābi ʿala l-ʿasha.
I invited my friends to dinner.
Key Takeaways
Store دعا / بيدعي / دعيت together. The perfect alternates among daʿa, daʿē-, and daʿ-; the imperfect is final -i. Aspect comes from perfect, بـ, licensed bare forms, حـ, and context. The frames دعا لـ and دعا على must be learned with their attached pronouns, and formal senses must be labeled separately.
