ماتكلمناش من زمان، فقعدنا ندردش عن الهواية والذكريات.

It is the verb تكلم (to talk/speak) in the past with the we ending, plus Egyptian negation:

• تكلمنا = we talked
• ما...ش = the common Egyptian way to negate many verbs
• ماتكلمناش = we didn’t talk

So the negation wraps around the verb: ما + تكلمنا + ش.

In casual writing, it is often written as one word, just like here.

Arabic often does not need a separate subject pronoun, because the verb already shows the subject.

Here, the ending -نا means we:

• تكلمنا = we talked
• قعدنا = we sat / we stayed / we started

So there is no need to add إحنا unless you want emphasis.

من زمان is a very common Egyptian expression meaning for a long time, in a long time, or for ages, depending on the sentence.

With a negative verb like ماتكلمناش, it usually corresponds to English:

• We haven’t talked in a long time
• We hadn’t talked for ages

So even though the Arabic form is past + negation, the most natural English translation is often present perfect.

The فـ is the conjunction so, then, or and so.

It links the second action to the first one as a result:

• ماتكلمناش من زمان، فقعدنا...
• We hadn’t talked in a long time, so we...

In Arabic spelling, this فـ is normally attached directly to the next word.

Literally, yes: قعد means to sit.

But in Egyptian Arabic, قعد often has a broader meaning, especially before another verb. It can mean:

• sat and...
• stayed there and...
• started / ended up...
• spent some time...

So فقعدنا ندردش does not only mean that you physically sat down. It more naturally means something like:

• so we sat chatting
• so we ended up chatting
• so we started chatting

This is a very common Egyptian pattern:

• قعد + imperfect verb

It often describes an action that followed and continued for a bit.

So:

• قعدنا ندردش = we sat chatting / we started chatting / we kept chatting

The imperfect ندردش is not really present tense here. It is part of this larger expression after قعدنا.

If you said قعدنا دردشنا, that would sound much less natural in this structure.

ندردش comes from دردش, which means to chat in a casual, friendly way.

It suggests light, informal conversation, not serious speech. So it is softer and more social than a plain نتكلم (we talk).

You can think of it as:

• chat
• have a little chat
• talk casually

It is definitely colloquial, not formal Standard Arabic.

Because عن is the normal preposition for the topic of conversation with verbs like يتكلم and يدردش.

So:

• نتكلم عن... = talk about...
• ندردش عن... = chat about...

In this sentence:

• ندردش عن الهواية والذكريات
• chat about the hobby and the memories

الهواية is singular because it most likely refers to one specific hobby that both people know about, or to the hobby as a known topic.

Arabic often uses the singular in places where English might use something broader or more flexible.

So:

• الهواية = the hobby / our hobby
• الهوايات = the hobbies

If the meaning were clearly plural, you would expect الهوايات instead.

Yes. اتكلم is very common in Egyptian Arabic, and many learners will hear ما اتكلمناش very often for we didn’t talk / we haven’t talked.

So these are close in meaning:

• ماتكلمناش
• ما اتكلمناش

For many speakers, اتكلم sounds more everyday-colloquial. تكلم is still understandable and used, but may feel a bit less typically Cairene to some ears.

Also, do not confuse this with ماكلمناش. That can lean more toward we didn’t contact someone / we didn’t speak to someone.

The definite article الـ is not pronounced the same way before every letter.

• الهواية: the ل is pronounced normally, because ه is a moon letter
  → il-hawāya / el-hawāya

• الذكريات: the ل is not pronounced, because ذ is a sun letter
  → iz-zikrayyāt / ez-zikrayyāt

So the phrase sounds roughly like:

• ʿan il-hawāya wiz-zikrayyāt

That assimilation is very common and important for natural pronunciation.
