النور في المطبخ كان مطفي، وفتحت المروحة كمان.

Yes. النور literally means the light, and in everyday Egyptian Arabic it is very commonly used for a lamp or electric light being on or off.

So النور في المطبخ means the light in the kitchen.

A learner might expect a word like ضوء, but النور is extremely natural in speech.

في means in, and المطبخ means the kitchen.

So:

• في = in
• المطبخ = the kitchen

Together: في المطبخ = in the kitchen

Egyptian Arabic often uses this very directly, just like English.

كان means was.

In النور في المطبخ كان مطفي, it links the subject with the state:

• النور = the light
• كان = was
• مطفي = off / switched off

So the structure is basically:

The light in the kitchen was off.

Without كان, the sentence would sound more like a present-time statement in many contexts. With كان, it clearly places the situation in the past.

مطفي means off, extinguished, or switched off.

It comes from the verb طفّى / يطفّي, which is used for turning something off, such as a light, TV, or other device.

Examples:

• النور مطفي = The light is off.
• التلفزيون مطفي = The TV is off.

So in this sentence, كان مطفي means was off.

Because مطفي is a very common colloquial participle-like form in Egyptian Arabic, used like an adjective.

This is extremely normal in speech. Egyptian often uses these forms for states:

• مفتوح = open
• مقفول = closed
• مطفي = off
• مولع or منور = on / lit, depending on context

So even though it may not look like a simple basic adjective to an English learner, it functions like one here: it describes the state of the light.

Literally, فتحت comes from فتح = to open.

But in Egyptian Arabic, فتح is also commonly used for turning some devices on, especially things like:

• a fan
• air conditioning
• TV
• radio
• water tap, etc.

So فتحت المروحة naturally means I turned on the fan or she turned on the fan, depending on context.

This is one of those places where a literal word-for-word translation can be misleading.

The -ت marks the past tense with either:

• I opened / I turned on
• she opened / she turned on

So فتحت is ambiguous by itself in Egyptian Arabic. It can mean either I opened/turned on or she opened/turned on.

You know which one it is from context, or from the translation already provided.

You usually know from context.

In Egyptian Arabic past tense:

• فتحت = I opened / she opened
• فتحتَ and فتحتِ distinctions are not usually shown in normal Arabic spelling without vowel marks, and Egyptian speech often relies on pronunciation and context

In writing without vowel marks, the form can be unclear. That is very normal.

So if the meaning has already been given to the learner, then that tells you whether the speaker means I or she here.

Because مروحة is a feminine noun in Arabic.

That matters because verbs and adjectives can agree with feminine nouns in some contexts.

Here, though, the verb فتحت does not necessarily show that the fan is the subject. In this sentence, the fan is the object: turned on the fan.

So المروحة is feminine as a noun, but فتحت is more likely telling you about the hidden subject: I or she turned on the fan.

كمان means also, too, or as well.

So:

• وفتحت المروحة كمان = and I/she turned on the fan too

It adds the idea that this happened in addition to something else.

Very common Egyptian word:

• أنا كمان = me too
• هو كمان = him too / he too

و means and.

So the sentence is made of two linked parts:

• النور في المطبخ كان مطفي
• وفتحت المروحة كمان

That gives:

The light in the kitchen was off, and I/she turned on the fan too.

In Egyptian Arabic, و is extremely common for connecting actions and ideas, just like and in English.

Yes, very normal.

The first part:

• النور في المطبخ كان مطفي Literally: the light in the kitchen was off

The second part:

• وفتحت المروحة كمان Literally: and turned on the fan too

Egyptian Arabic often allows a hidden subject when it is understood from the verb or context, so not saying I or she explicitly is completely natural.

Because the sentence is talking about specific things:

• النور = the light
• المطبخ = the kitchen
• المروحة = the fan

This is very natural if the speaker and listener both know which kitchen and which fan are being discussed.

Arabic often uses the definite article where English would too, and sometimes even where English might not.

Yes. Egyptian has several natural ways to express similar ideas.

For example, instead of مطفي, someone might say something involving النور مش منور in some contexts, though that changes the wording slightly.

Also, instead of فتحت المروحة, some speakers might prefer other verbs depending on region or habit, but فتحت المروحة is very common and natural.

So this sentence is not the only possible version, but it is perfectly normal Egyptian Arabic.

A rough pronunciation would be:

en-nūr fil-maṭbax kān maṭfi, w-fataḥt il-mirwaha kamān

A few notes:

• النور is usually pronounced en-nūr
• المطبخ in Egyptian is often il-maṭbax or el-maṭbax
• المروحة is often il-mirwaha or el-mirwaha
• كمان is kamān

This is only an approximate guide, but it can help connect the written sentence to spoken Egyptian Arabic.
