Egyptian uses زي ما when one action, situation, or manner provides a real model for another: اعمل زي ما اتفقنا “Do it as we agreed.” It uses كأن when something merely looks, sounds, or behaves as if another proposition were true: بيتكلم كأنه المدير “He talks as if he were the manager.”
That factuality contrast is more useful than memorizing both as translations of English like/as. زي ما points to an actual way, instruction, precedent, or matching fact. كأن asks the listener to imagine a comparison; the speaker need not believe its clause literally.
Rule 1: use زي before a noun, زي ما before a clause
Like قبل and بعد, زي changes shape according to its complement. A noun follows زي directly. A finite clause normally follows زي ما.
| Complement | Pattern | Meaning |
|---|---|---|
| noun | زي أخوه | like his brother |
| clause | زي ما أخوه بيعمل | the way his brother does |
| noun | زي الأول | like before / as it used to be |
| clause | زي ما كان في الأول | the way it was at first |
اعملها زي ما شرحتلك امبارح.
iʿmalha zayy ma sharaḥtilak imbāriḥ.
Do it the way I explained to you yesterday. (to a man)
الولد ده بيتكلم زي أبوه.
il-walad da biyitkallim zayy ʾabūh.
This boy talks like his father.
الولد ده بيتكلم زي ما أبوه كان بيتكلم.
il-walad da biyitkallim zayy ma ʾabūh kān biyitkallim.
This boy talks the way his father used to talk.
The noun comparison only identifies a similar person. The clause comparison specifies a matching manner and its own past-habit predicate.
Rule 2: زي ما treats the comparison as an actual model
The model may be an earlier agreement, a demonstrated method, a repeated pattern, or a fact that the speaker accepts.
رتبت الملفات زي ما المدير طلب.
rattabt il-malafāt zayy ma l-modīr ṭalab.
I arranged the files the way the manager requested.
زي ما توقعت، القطر اتأخر.
zayy ma twaʾʾaʿt, il-ʾaṭr itʾakhkhar.
Just as I expected, the train was delayed.
حنقسم الشغل زي ما عملنا المرة اللي فاتت.
ḥan-ʾassim ish-shoghl zayy ma ʿamilna l-marra lli fātit.
We’ll divide the work the way we did last time.
Initial زي ما توقعت frames the whole following claim. Final زي ما... more often specifies how the main action is performed. A comma ، helps separate a longer initial frame.
Rule 3: كأن introduces apparent or imagined resemblance
كأن can take an attached subject suffix—كأني، كأنك، كأنه، كأنها، كأنهم—or a full noun phrase. The proposition supplies the imagined scene against which reality is compared.
بيتكلم كأنه المدير.
biyitkallim kaʾannu l-modīr.
He talks as if he were the manager.
بصلي كأنه مايعرفنيش.
baṣṣli kaʾannu ma-yiʿrafnīsh.
He looked at me as if he didn’t know me.
كأن الدنيا حتمطر، خد شمسية.
kaʾann id-dunya ḥa-timṭar, khod shamsiyya.
It looks as if it’s going to rain; take an umbrella. (to a man)
The speaker does not assert that he is the manager, that he genuinely failed to recognize the speaker, or that rain is certain. كأن marks a resemblance or inference based on appearance.
In fast colloquial speech and informal spelling, variants such as كإن and reduced pronunciations occur (informal/social variation). This page keeps كأن as its consistent house form.
Rule 4: choose aspect inside each comparison normally
Neither linker erases aspect. Use بـ for ongoing or habitual activity, the perfect for a bounded model, كان + بـ for a past habit, and حـ for a future situation.
هو بيفتح المحل بدري زي ما أبوه كان بيعمل.
huwwa biyiftaḥ il-maḥall badri zayy ma ʾabūh kān byiʿmil.
He opens the shop early, the way his father used to.
حكلمها زي ما وعدتها.
ḥa-kallimha zayy ma waʿadtaha.
I’ll call her as I promised her.
كان ماشي بسرعة كأنه متأخر على طيارة.
kān māshi bisorʿa kaʾannu mitʾakhkhar ʿala ṭayyāra.
He was walking fast as if he were late for a flight.
The forms differ because the meanings differ: a current habit matches a past habit; a future action fulfills a completed promise; a past scene contains an apparent state.
Rule 5: subject continuity and negation stay local
The comparison can keep the main subject or introduce a different one. State a changed subject inside the comparison when context does not already identify it.
عملت الأكل زي ما أمي علمتني.
ʿamilt il-ʾakl zayy ma ʾommi ʿallimitni.
I made the food the way my mother taught me.
دخلت بهدوء كأني مش موجود.
dakhalt bi-hodūʾ kaʾinni mish mawgūd.
I went in quietly as if I weren’t there.
الطلب ماوصلش زي ما الشركة وعدتنا.
iṭ-ṭalab ma-wiṣilsh zayy ma sh-sharika waʿaditna.
The order didn’t arrive the way the company promised us.
The last sentence negates the actual arrival, not the promise. If the imagined comparison itself contains a finite negative verb, use ما...ش, as in كأنه مايعرفنيش. A nonverbal imagined predicate instead uses مش, as in كأني مش موجود.
زي ما versus كأن
| Question | Choose | Core effect |
|---|---|---|
| Is this an actual method, precedent, or accepted match? | زي ما | “as / the way” |
| Is this only how something appears or behaves? | كأن | “as if” |
| Does only a noun follow? | زي | “like” |
قال الكلام النهارده زي ما قاله امبارح بالظبط.
ʾāl il-kalām in-nahārda zayy ma ʾālo imbāriḥ biẓ-ẓabṭ.
He said it today exactly the way he said it yesterday. (actual repeated wording or manner)
قال الكلام كأنه حافظه.
ʾāl il-kalām kaʾannu ḥāfẓo.
He said it as if he had memorized it. (the speaker infers this from his delivery)
A short contextual exchange
أرتب العرض إزاي؟
ʾarattib il-ʿarḍ ʾizzāy?
How should I organize the presentation?
رتبه زي ما عملنا الأسبوع اللي فات، بس ماتقراش كأنك مستعجل.
rattibo zayy ma ʿamilna l-ʾusbūʿ illi fāt, bass ma-tiʾrāsh kaʾannak mistaʿgil.
Organize it the way we did last week, but don’t read as though you’re in a hurry. (to a man)
The first comparison supplies a real template; the second warns against creating an artificial impression.
Register and variation
زي ما is mainstream everyday Egyptian (informal/neutral). Formal MSA-oriented كما is common in essays, official speech, and deliberate code-switching (formal). كأن is shared across registers, but Cairene suffix vowels, verb forms, and the absence of MSA case endings distinguish the colloquial construction.
Alexandrian, Delta, Upper Egyptian, Bedouin, age, class, and community varieties use different words and pronunciations for “like” (regional/social). Performance speech may exaggerate كأنه to signal mockery or disbelief (performance language). The forms here follow mainstream urban Cairo.
Common Mistakes
Omitting ما before a finite comparison clause
❌ اعملها زي شرحتلك.
Incorrect—a finite clause after زي needs ما.
✅ اعملها زي ما وريتهالك.
iʿmalha zayy ma warrēthālak.
Do it the way I showed it to you. (to a man)
Using زي ما for an unreal appearance
❌ بيتصرف زي ما هو صاحب المكان.
Incorrect for the intended ‘as if’ reading—this is an imagined identity, not an actual model.
✅ بيتصرف كأنه صاحب المكان.
biyitṣarraf kaʾannu ṣāḥib il-makān.
He acts as if he owns the place.
Negating a finite verb with مش
❌ بصلي كأنه مش يعرفني.
Incorrect—finite يعرف takes circumfixal ما...ش.
✅ سلم عليا كأنه ماشافنيش من سنين.
sallim ʿalayya kaʾannu ma-shāfnīsh min sinīn.
He greeted me as if he hadn’t seen me in years.
Breaking a habitual comparison with a one-time perfect
❌ هو بيفتح بدري زي ما أبوه عمل كل يوم.
Incorrect for the intended past habit—عمل describes a bounded event.
✅ هو بيفتح بدري زي ما أبوه كان بيعمل زمان.
huwwa biyiftaḥ badri zayy ma ʾabūh kān byiʿmil zamān.
He opens early, the way his father used to long ago.
Treating formal كما as the neutral conversational default
رتب الملفات كما طلب المدير.
rattib il-malafāt kamā ṭalab il-modīr.
Arrange the files as the manager requested. (formal MSA-oriented wording)
✅ رتب الملفات زي ما المدير طلب.
rattib il-malafāt zayy ma l-modīr ṭalab.
Arrange the files the way the manager requested. (neutral Cairene)
