كل ما نطلع السطح، بنسمع الجرس من المدخل اللي تحت.

كل ما means whenever, every time, or each time that.

So:

• كل ما نطلع السطح = whenever we go up to the roof
• It introduces something that happens repeatedly, not just one time.

This is different from a simple when in a one-time situation. كل ما strongly suggests a repeated pattern.

Because the verb already includes the subject.

In Egyptian Arabic:

• نطلع = we go up / we go out / we climb
• بنسمع = we hear

The نـ at the beginning shows we. Arabic often does not need a separate pronoun unless you want extra emphasis.

So you could say إحنا بنسمع, but it is not necessary here.

This is a very common question.

In Egyptian Arabic, بـ often marks the normal present or habitual meaning:

• بنسمع = we hear / we usually hear

After expressions like كل ما, the verb is often used without بـ:

• كل ما نطلع = whenever we go up

So the pattern here is very natural:

• كل ما نطلع... = whenever we go up...
• بنسمع... = we hear...

You may also hear some variation in everyday speech, but this sentence is perfectly normal as written.

Because in Egyptian Arabic, طلع can directly take the place you are going up to.

So:

• نطلع السطح = we go up to the roof
• literally, it looks like we ascend the roof

This is very common in colloquial Arabic. English usually needs to, but Egyptian Arabic often does not here.

Usually السطح means the roof / rooftop of a building.

In many Egyptian contexts, this often means the accessible flat rooftop, not just the outside top surface in an abstract sense. So depending on context, roof or rooftop can both work in English.

It means from the entrance downstairs or from the entrance below.

Breakdown:

• من = from
• المدخل = the entrance
• اللي تحت = that is downstairs / that is below

Here من shows the source of the sound:

• بنسمع الجرس من المدخل اللي تحت = we hear the bell coming from the entrance downstairs

اللي is the Egyptian Arabic relative word that often corresponds to English who, which, or that.

Here:

• المدخل اللي تحت
• literally: the entrance that is below

So اللي connects المدخل with the description تحت.

In Egyptian Arabic, اللي is extremely common and very useful because it covers several English relative words.

It describes the entrance.

So the structure is:

• من [المدخل اللي تحت]
• from [the entrance downstairs]

It does not mean the bell downstairs.

If you wanted to say the bell downstairs, you would more naturally say:

• الجرس اللي تحت

It can mean either, depending on context.

• الجرس = the bell
• In everyday building/house context, it is often understood as the doorbell

Since the sentence mentions the entrance downstairs, many learners would naturally understand it as a doorbell or entrance bell.

Because they refer to specific, identifiable things in the situation:

• السطح = the roof of that building
• الجرس = the bell being talked about
• المدخل = the entrance being referred to

Arabic often uses the definite article when the thing is understood from context, even where English might sometimes be a little looser.

Sometimes learners want to replace كل ما with لما, but they are not exactly the same.

• كل ما = whenever / every time
• لما = often when

In this sentence, كل ما is better because the meaning is clearly repeated:

• Every time we go up to the roof, we hear the bell...

If you used لما, it could sound more like a simple when statement, depending on context.

Yes. Arabic can often move the time clause around.

For example, you could say:

• بنسمع الجرس من المدخل اللي تحت كل ما نطلع السطح.

That still means roughly:

• We hear the bell from the entrance downstairs whenever we go up to the roof.

Putting كل ما نطلع السطح first makes the whenever idea feel more prominent.

A simple transliteration would be:

• kull ma nitlaʿ is-saṭḥ, binsmaʿ il-garas min il-madkhal illi taḥt

A few pronunciation notes:

• السطح is pronounced roughly is-saṭḥ because the l of الـ assimilates before s
• اللي is often pronounced illi
• تحت ends with a strong ḥ sound, not an English h

Exact pronunciation varies a bit by speaker, but this is a good practical guide.
