الاجتماع خلص متاخر، بس المدير قال لنا الحل.

With something like الاجتماع (the meeting), خلص means finished, ended, or was over. So الاجتماع خلص means the meeting ended.

In Egyptian Arabic, خلص is a very common everyday verb for something being done or finished.

Here متأخر / متاخر means late, and it is describing how the meeting ended: it ended late.

So the structure is basically:

الاجتماع خلص متاخر
= the meeting ended late

Arabic often puts this kind of word after the verb.

متأخر is the more careful spelling, with a hamza. In informal writing, especially online or in texting, many Arabic speakers leave the hamza out, so متاخر is very common.

The meaning does not change. It is still late.

It can mean either one, depending on context.

In this sentence, بس means but, because it connects two ideas:

• The meeting ended late
• but the manager told us the solution

If it meant only, the sentence structure would be different.

Because Arabic normally uses قال + لِـ + person for say to someone.

So:

• قال = said
• لنا = to us

Together, قال لنا means said to us or told us.

That لـ is the normal pattern with قال when you mention who heard the speech.

لنا literally means to us or for us, depending on context. In this sentence, it means to us.

So:

• قال لنا = he said to us
• natural English: he told us

الحل literally means the solution. Depending on context, it can also feel like the answer, the fix, or the way to solve the problem.

So in this sentence, it means the manager told them what the solution was.

Because it is definite: the solution, not just a solution.

The same is true for:

• الاجتماع = the meeting
• المدير = the manager
• الحل = the solution

The prefix الـ is the Arabic equivalent of the.

It is very natural and understandable in Egyptian Arabic, but it is a bit mixed in register.

Some parts feel especially colloquial, like:

• خلص
• بس

Other words, like الاجتماع and المدير, are used in both Egyptian Arabic and Modern Standard Arabic.

That kind of mix is very normal in real life.

A rough Egyptian pronunciation would be:

el-egtimāʿ khalaṣ mota'akhkhar, bas el-modīr ʔāl lena el-ḥall

A few useful notes:

• الـ often sounds like el-
• ق in قال is usually pronounced as a glottal stop ʔ in Cairene Egyptian, so قال sounds like ʔāl
• الحل ends with a doubled l sound: el-ḥall

Exact pronunciation can vary a little from one speaker to another.
