Valency is the participant frame a verb licenses: whether it has only a subject, takes a direct object, introduces another participant with a preposition, or embeds a clause. Egyptian derived forms often reorganize this frame, but no Roman numeral guarantees one syntactic behavior. كسر is transitive, انكسر is intransitive, قابل takes a direct object, اتقابل commonly uses مع, and Form X استعمل is transitive while استغرب من is prepositional.
This matters because English frequently uses one surface verb for several frames: “The door opened / I opened the door.” Egyptian often chooses a different stem, and pronoun attachment makes the difference audible. The focused comparison of related lexical meanings is on Choosing among Related Derived Forms.
A practical valency map
| Verb | Core frame | What the syntax profiles |
|---|---|---|
| كسر kasar | فاعل + فعل + مفعول | an agent acts on an object |
| انكسر inkasar | متأثر + فعل | the affected thing undergoes a change |
| علّم ʿallim | معلّم + متعلّم + محتوى | a causer transfers knowledge |
| اتعلم itʿallim | متعلّم + محتوى + من المصدر | the learner acquires knowledge |
| قابل ʾābil | فاعل + شخص مفعول | one participant is syntactically central |
| اتقابل itʾābil | مشاركون / فاعل + مع | the encounter is mutual |
| استعمل istaʿmil | فاعل + أداة مفعول | an agent uses a resource |
| استغرب istaghrab | فاعل + من / إن | a person reacts to a stimulus or proposition |
The Arabic labels in the middle column are analytical shorthand, not a demand for formal MSA syntax in speech. The actual Cairene examples below carry no case or mood endings.
Rule 1: a middle stem can remove the external agent
Compare transitive كسر with Form VII انكسر. The first clause has an agent and a direct object. The second makes the affected entity its subject and leaves the cause unexpressed or adds it as a circumstance.
الهوا كسر فرع الشجرة.
il-hawa kasar farʿ ish-shagara.
The wind broke the tree branch.
فرع الشجرة انكسر من الهوا.
farʿ ish-shagara inkasar min il-hawa.
The tree branch broke in the wind.
Form VII is not a free passive that licenses a formal “by-agent” phrase. If the agent is discourse-important, the transitive clause is usually clearer. If the event or result is central, the middle clause is natural.
الكوباية انكسرت لوحدها.
il-kubbāya inkasrit liwaḥdaha.
The glass broke by itself.
Rule 2: causative and learning frames distribute participants differently
Form II علّم can license the teacher, learner, and taught content. Form V اتعلّم promotes the learner to subject; the source, if mentioned, uses من. This is a valency alternation, not merely a change in intensity.
سلمى علمت أخوها الإنجليزي.
Salma ʿallimit ʾakhūha l-inglīzi.
Salma taught her brother English.
أخوها اتعلم الإنجليزي منها.
ʾakhūha itʿallim il-inglīzi minha.
Her brother learned English from her.
هي علمته ينطق الاسم صح.
hiyya ʿallimitu yinṭaʾ il-ism ṣaḥḥ.
She taught him to pronounce the name correctly.
The object suffix in علّمته is licensed by the transitive/causative frame. With اتعلم منه, the same person is expressed after من: اتعلمت منه “I learned from him.”
Rule 3: reciprocal viewpoint often changes the complement
Form III قابل commonly takes a direct object. Form VI اتقابل presents the meeting as joint; a plural subject may contain both participants, or a singular subject adds the other participant with مع.
قابلت نادر في المكتب.
ʾābilt Nādir fil-maktab.
I met Nader at the office.
اتقابلت مع نادر في المكتب.
itʾābilt maʿ Nādir fil-maktab.
I met up with Nader at the office.
اتقابلنا في المكتب وراجعنا الخطة.
itʾābilna fil-maktab wi-rāgaʿna l-khuṭṭa.
We met at the office and reviewed the plan.
The English translations overlap, so the Egyptian complement frame must be learned directly. English meet with is a helpful comparison, but it is not a word-for-word rule for every encounter verb.
Rule 4: Form X has no single valency
استعمل takes the thing used directly, استحمل takes what is endured, and استغرب commonly uses من for a stimulus or إن for a proposition. The shared استـ prefix predicts none of these frames.
استعملنا الخريطة عشان نوصل.
istaʿmilna l-kharīṭa ʿashān nūṣal.
We used the map to get there.
مااستحملتش الحر، فرجعت بدري.
ma-staḥmiltish il-ḥarr, fa-ragaʿt badri.
I couldn’t stand the heat, so I came back early.
استغربت من رده على الرسالة.
istaghrabt min raddu ʿala r-risāla.
I was surprised by his reply to the message.
استغربت إنه رد بسرعة.
istaghrabt innu radd bisurʿa.
I was surprised that he replied quickly.
Rule 5: aspect changes time viewpoint, not valency
The complement frame remains stable across perfect, b-imperfect, bare imperfect, and future forms. Aspectual markers tell you how the event is viewed; they do not create or remove an object.
Time-context minimal pair
استعملت الجهاز مرة امبارح.
istaʿmilt il-gihāz marra imbāriḥ.
I used the device once yesterday.
بستعمل الجهاز كل يوم.
bastaʿmil il-gihāz koll yōm.
I use the device every day.
Positive-to-negative pair
قابلته بعد المحاضرة.
ʾābiltu baʿd il-muḥāḍara.
I met him after the lecture.
ماقابلتوش بعد المحاضرة.
ma-ʾābiltūsh baʿd il-muḥāḍara.
I didn’t meet him after the lecture.
The object suffix comes before negative -ش. With a prepositional frame, the pronoun attaches to the preposition instead: ماتقابلتش معاه “I didn’t meet up with him.”
Agreement, register, and variation
Valency does not suspend agreement: هي اتعلمت, هم اتعلموا, إنتي بتستعملي. Nor does it force one tense: the perfect, b-imperfect, bare imperfect, and حـ future all preserve the lexical complement frame.
MSA and formal Egyptian may prefer a different passive construction or a learned verb, especially in news and institutional prose (formal/academic). Everyday Cairene often uses a middle verb, an unspecified plural agent, or a participial result. These are structured register choices. Regional varieties may choose انكسر versus اتكسر at different rates and may realize ق as /q/ or /g/; the Cairene production baseline here uses /ʾ/ and the forms displayed.
A two-turn Cairene dialogue
مين كسر الشاشة؟
mīn kasar ish-shāsha?
Who broke the screen?
معرفش، لقيتها انكسرت وهي في الشنطة.
maʿrafsh, laʾētha inkasrit wi-hiyya fish-shanṭa.
I don’t know; I found that it had broken while it was in the bag.
Common Mistakes
Giving an intransitive middle a direct object
❌ الهوا انكسر فرع الشجرة.
Incorrect—the middle verb makes the branch its subject; it cannot take the branch as a direct object.
✅ الهوا كسر فرع الشجرة.
il-hawa kasar farʿ ish-shagara.
The wind broke the tree branch.
Adding an English-style agent to the middle clause
❌ العامل انكسر الفرع.
Incorrect—the intransitive middle cannot take the worker as agent-subject and the branch as its object.
✅ العامل كسر الفرع بالغلط.
il-ʿāmil kasar il-farʿ bil-ghalaṭ.
The worker broke the branch by accident.
Using a direct object where مع is selected
❌ اتقابلت نادر بعد الشغل.
Incorrect for the intended reciprocal Form VI frame—use مع with the co-participant.
✅ اتقابلت مع نادر بعد الشغل.
itʾābilt maʿ Nādir baʿd ish-shoghl.
I met up with Nader after work.
Copying the preposition from the English gloss
❌ استغربت على النتيجة.
Incorrect in the intended Cairene frame—استغرب selects من here.
✅ استغربت من النتيجة.
istaghrabt min in-natīga.
I was surprised by the result.
Separating the negative object clitic
❌ ماقابلتش هو امبارح.
Incorrect for ‘I didn’t meet him’—the object precedes final -ش inside the verb word.
✅ ماقابلتوش امبارح.
ma-ʾābiltūsh imbāriḥ.
I didn’t meet him yesterday.
Letting aspect erase the complement frame
❌ هو يستغرب السعر كل مرة.
Incorrect as a neutral habitual clause, and the intended stimulus frame is missing من.
✅ هو بيستغرب من السعر كل مرة.
huwwa biyistaghrab min is-siʿr koll marra.
He is surprised by the price every time.
Key Takeaways
Derived morphology can add a causer, profile an affected subject, or present participation as mutual, but these are tendencies within lexical families. Learn whether each Egyptian verb is intransitive, transitive, prepositional, or clause-taking. Agreement and aspect operate on that stored frame; they do not replace it.
