كتب katab — write | Arabic (Egyptian) Grammar

كتب / بيكتب katab / biyiktib is the everyday Cairene verb “write.” It is a strong Form I verb from the root ك-ت-ب and a useful model for regular person endings, but one fact remains lexical: the perfect has a–a, while the imperfect uses i. The unvocalized letters كتب do not predict yiktib, so learn the pair rather than reconstructing it from English or MSA. The wider dictionary-form method applies the same principle to other verbs.

Writing also exposes several important complement choices. The thing written is a direct object; a recipient takes لـ; a topic takes عن; a language normally takes بـ; and a physical surface takes على. English often hides these contrasts inside write someone, write about, and write in, which is why the Egyptian frame matters as much as the conjugation.

Complete practical paradigm

The forms below are mainstream urban Cairene (informal/neutral). Bare imperfect forms follow modal or control expressions. بـ supports ordinary independent ongoing and habitual clauses, while joined حـ marks projected events.

Person	Perfect	Bare imperfect	b-imperfect	ḥa-future
أنا	كَتَبْتْ katabt	أَكْتِبْ ʾaktib	بَكْتِبْ baktib	حَكْتِبْ ḥa-ktib
إنت	كَتَبْتْ katabt	تِكْتِبْ tiktib	بِتِكْتِبْ bitiktib	حَتِكْتِبْ ḥa-tiktib
إنتي	كَتَبْتِي katabti	تِكْتِبِي tiktibi	بِتِكْتِبِي bitiktibi	حَتِكْتِبِي ḥa-tiktibi
هو	كَتَبْ katab	يِكْتِبْ yiktib	بِيِكْتِبْ biyiktib	حَيِكْتِبْ ḥa-yiktib
هي	كَتَبِتْ katabit	تِكْتِبْ tiktib	بِتِكْتِبْ bitiktib	حَتِكْتِبْ ḥa-tiktib
إحنا	كَتَبْنَا katabna	نِكْتِبْ niktib	بِنِكْتِبْ biniktib	حَنِكْتِبْ ḥa-niktib
إنتوا	كَتَبْتُوا katabtu	تِكْتِبُوا tiktibu	بِتِكْتِبُوا bitiktibu	حَتِكْتِبُوا ḥa-tiktibu
هم	كَتَبُوا katabu	يِكْتِبُوا yiktibu	بِيِكْتِبُوا biyiktibu	حَيِكْتِبُوا ḥa-yiktibu

كتبت الطلب امبارح وسلمته بنفسي.

katabt iṭ-ṭalab imbāriḥ wi-sallamto binafsi.

I wrote the application yesterday and handed it in myself.

هي بتكتب ملخص بعد كل محاضرة.

hiyya bitiktib molakhkhaṣ baʿd koll moḥāḍara.

She writes a summary after every lecture.

حكتب الملاحظات في ملف واحد وأبعته للفريق.

ḥa-ktib il-molāḥaẓāt fi malaff wāḥid wa-ʾabʿato lil-farīʾ.

I’ll put the notes in one file and send it to the team.

The direct object is what gets written

Use a direct object for the produced text or content: كتب رسالة، كتب اسمه، كتب تقرير. An attached object replaces that text: كتبته “I wrote it,” كتبها “he wrote it.” The suffix does not mean the recipient.

الفكرة كانت معقدة، فكتبتها في سطرين أبسط.

il-fikra kānit moʿaʾʾada, fa-katabtha fi saṭrēn ʾabsaṭ.

The idea was complicated, so I wrote it in two simpler lines.

ماكتبتهوش بإيدي؛ استخدمت الإملا الصوتي.

ma-katabtūsh bi-ʾīdi; istakhdamt il-ʾimla ṣ-ṣōti.

I didn’t type it myself; I used voice dictation.

Here English write naturally includes handwriting and composing text. Digital typing also commonly uses كتب in Egyptian; طبع has narrower printing/typing uses depending on context.

Recipients take لـ

For “write to someone,” attach or state لـ: كتب لمريم، كتبلها، اكتبلي. English can say write me a message without to, but Egyptian does not make the person a direct object of كتب. The message remains the direct object.

كتبت لمديرتي رسالة قصيرة وطلبت ميعاد.

katabt li-modīrti risāla ʾoṣayyara wi-ṭalabt mīʿād.

I wrote my manager a short message and asked for an appointment.

اكتبلي العنوان في رسالة عشان ما أنساهوش.

iktibli l-ʿunwān fi risāla ʿashān ma ʾansāhūsh.

Write me the address in a message so I don’t forget it. (to one man)

💡

Separate the two roles: كتبها means “wrote it,” while كتبلها means “wrote to/for her.” The consonant ل is the recipient marker, not part of the object suffix.

Topic, language, and surface

Use عن for what a text is about: كتب مقال عن المواصلات. Use بـ for the language or writing medium: كتب بالعربي، كتب بالقلم. Use على for a physical or digital surface: كتب على الورقة، كتب على السبورة. في locates text inside a document, message, or field.

الصحفية كتبت عن الزحمة وتأثيرها على الشغل.

iṣ-ṣoḥofiyya katabit ʿan iz-ziḥma wi-taʾsīrha ʿala sh-shoghl.

The journalist wrote about traffic and its effect on work.

اكتبي اسمك بالعربي والإنجليزي فوق الصورة.

iktibi smik bil-ʿarabi wil-ʾinglīzi fōʾ iṣ-ṣūra.

Write your name in Arabic and English above the photo. (to one woman)

حد كتب رقمه على الكرتونة بقلم أسود.

ḥadd katab raʾamo ʿala l-kartōna bi-ʾalam ʾaswad.

Someone wrote their number on the box with a black pen.

These prepositions are semantic, not interchangeable decoration. عن identifies subject matter; بـ identifies language or instrument; على identifies the supporting surface.

Commands and negation

Positive commands are اكتب iktib, اكتبي iktibi, and اكتبوا iktibu. Negative commands use the second-person imperfect inside ما...ش: ماتكتبش، ماتكتبيش، ماتكتبوش. In statements, ماكتبش is perfect “he didn’t write,” while مابيكتبش is b-imperfect “he doesn’t write/isn’t writing.”

اكتبوا أسئلتكم في الشات وأنا هرد في الآخر.

iktibu ʾasʾiltokom fish-shāt wi-ʾana harodd fil-ʾākhir.

Write your questions in the chat, and I’ll answer at the end. (to several people)

ماتكتبش الرقم على الظرف من بره.

ma-tiktibsh ir-raʾam ʿala ẓ-ẓarf min barra.

Don’t write the number on the outside of the envelope. (to one man)

ماكتبتش التقرير امبارح عشان البيانات كانت ناقصة.

ma-katabtish it-taʾrīr imbāriḥ ʿashān il-bayānāt kānit nāʾṣa.

I didn’t write the report yesterday because the data was incomplete.

كاتب and مكتوب

The active participle كاتب kātib, feminine كاتبة, plural كاتبين, can be the profession noun “writer/author” or a resultative participle “having written.” It does not normally describe typing in progress; use بيكتب for that. The passive participle مكتوب maktūb means “written” and can predicate a result without a present copula.

أنا كاتب كل التفاصيل في الإيميل؛ راجعه قبل الاجتماع.

ʾana kātib koll it-tafāṣīl fil-ʾimēl; rāgiʿo ʾabl il-igtimāʿ.

I’ve written all the details in the email; review it before the meeting.

اسم العيلة مكتوب غلط على التذكرة.

ism il-ʿēla maktūb ghalaṭ ʿala t-tazkara.

The family name is written incorrectly on the ticket.

مكتوب also occurs in the lexicalized idea “destined/written,” while كاتب as a noun may refer to an author or writer. Those meanings are conventional parts of the root family, not a reason to translate every English use of written mechanically. The maṣdar كتابة kitāba means writing; it is common both conversationally and institutionally.

A cultural collocation

كتب الكتاب literally contains the verb and noun from the same root, but in Egyptian family and legal contexts كتب الكتاب means concluding the Islamic marriage contract (cultural/legal; neutral). This is a fixed collocation, not simply “write the book.” Context normally disambiguates it from authoring a book.

كتبوا الكتاب في البيت، والفرح بعد شهرين.

katabu l-kitāb fil-bēt, wi-l-faraḥ baʿd shahrēn.

They held the marriage-contract ceremony at home, and the wedding celebration is in two months.

A short dialogue

أ: كتبت للدكتور عن النتيجة ولا لسه؟

A: katabt lid-duktōr ʿan in-natīga walla lissa?

A: Have you written to the doctor about the result yet?

ب: كتبتله الصبح، بس لسه ماردش عليا.

B: katabtilo ṣ-ṣobḥ, bass lissa ma-raddish ʿalayya.

B: I wrote to him this morning, but he still hasn’t replied to me.

Register and variation

Formal MSA has related كَتَبَ / يَكْتُبُ (formal/MSA). Ordinary Cairo has كَتَبْ / بِيِكْتِبْ, with no final case or mood endings and a different imperfect vowel. Formal administrative collocations can enter educated Egyptian speech (professional/code-switched) without turning the entire clause into MSA. Regional Egyptian and community varieties may shift short vowels or prefer different digital vocabulary (regional/social); this page keeps the mainstream Cairene pair katab / yiktib.

Common Mistakes

1. Guessing the imperfect vowel from MSA or the perfect.

هو بيكتب بسرعة على اللابتوب.

huwwa biyiktib bisorʿa ʿala l-lābtob.

huwwa biyaktob bisorʿa ʿala l-lābtob.

Pronunciation error—the mainstream Cairene imperfect is yiktib.

✅ هو بيكتب بسرعة من غير ما يبص للكيبورد.

huwwa biyiktib bisorʿa min ghēr ma yiboṣṣ lil-kībōrd.

He types quickly without looking at the keyboard.

2. Making the recipient a direct object.

❌ كتبت صاحبي رسالة طويلة.

Incorrect for ‘I wrote my friend a long message’—the recipient needs لـ.

✅ كتبت لصاحبي رسالة طويلة عن الرحلة.

katabt li-ṣāḥbi risāla ṭawīla ʿan ir-riḥla.

I wrote my friend a long message about the trip.

3. Omitting عن before a topic.

❌ كتبت مقال المواصلات في القاهرة.

Wrong for the intended ‘article about transportation’ relation—use عن for the topic.

✅ كتبت مقال عن المواصلات في القاهرة بعد التجربة.

katabt maʾāl ʿan il-mowāṣalāt fil-ʾāhira baʿd it-tagriba.

I wrote an article about transportation in Cairo after the experience.

4. Using bare imperfect as an independent current clause.

❌ أنا أكتب الرد دلوقتي.

Incorrect for neutral ongoing Cairene—the main-clause imperfect needs بـ.

✅ أنا بكتب الرد دلوقتي، فاستنى خمس دقايق.

ʾana baktib ir-radd dilwaʾti, fa-stanna khams daʾāyiʾ.

I’m writing the reply now, so wait five minutes.

5. Putting the object after negative ـش.

❌ ماكتبتش ها في النسخة الأخيرة.

Incorrect—the direct-object suffix must remain inside the negative circumfix.

✅ ماكتبتهاش في النسخة الأخيرة عشان المعلومة مش مؤكدة.

ma-katabthāsh fin-noskha l-ʾakhīra ʿashān il-maʿlūma mish moʾakkada.

I didn’t write it in the final version because the information isn’t confirmed.

Key Takeaways

Memorize كتب / بيكتب as katab / biyiktib; the imperfect vowel is lexical.
Use a direct object for text, لـ for the recipient, عن for the topic, بـ for language or instrument, and على for the surface.
Distinguish بيكتب “is writing/writes,” كاتب “writer/having written,” and مكتوب “written.”
Commands, future حـ, object clitics, and ما...ش attach to the regular Cairene stem without importing MSA endings.
