اول ما الاجتماع يخلص، هنروح البنك.

اول ما means as soon as or once.

In Egyptian Arabic, it is a very common way to introduce an action that happens immediately after another one.

So:

• اول ما الاجتماع يخلص = as soon as the meeting ends

You can think of اول ما + clause as a fixed pattern:

• اول ما أوصل، هكلمك = As soon as I arrive, I’ll call you
• اول ما يجي، نبدأ = As soon as he comes, we’ll start

In this expression, ما is part of the set phrase اول ما. You should usually learn it as one chunk.

It does not mean what here. Instead, it helps form the time expression as soon as / when.

So:

• اول alone = first / beginning
• اول ما = as soon as

Because after اول ما, Egyptian Arabic often uses the present tense to talk about a future event in a time clause.

So even though the meaning in English is future:

• As soon as the meeting ends, we’ll go to the bank

Arabic says it with present forms:

• الاجتماع يخلص
• literally: the meeting finishes

This is normal and very common.

يخلص comes from the verb خلص.

In this sentence, it means:

• to finish
• to end
• to be over

So الاجتماع يخلص means:

• the meeting ends
• the meeting is over
• the meeting finishes

In Egyptian Arabic, خلص is a very common verb with a few related meanings depending on context, such as finish, be done, or be over.

Because the sentence means the meeting ends, not we finish the meeting.

Compare:

• الاجتماع يخلص = the meeting ends
  The meeting is the thing that finishes.

• نخلص الاجتماع = we finish the meeting
  Here we are actively finishing it.

Both are possible in different contexts, but they mean slightly different things.

هنروح means we will go.

It is made of:

• هـ / حـ = future marker in Egyptian Arabic
• نروح = we go

So:

• نروح = we go
• هنروح = we’ll go / we will go

In Egyptian Arabic, the future is often formed with هـ or حـ before the present-tense verb:

• هعمل = I’ll do
• هتيجي = you’ll come
• هنروح = we’ll go

Depending on spelling style, you may also see:

• حنروح

Both represent Egyptian speech.

In Egyptian Arabic, راح / يروح is a very common verb meaning to go.

So:

• أروح = I go
• تروح = you go
• يروح = he goes
• نروح = we go

This is one of the main everyday verbs for movement in Egyptian Arabic.

البنك literally means the bank because of الـ.

In real usage, Arabic often uses the definite article where English might say the bank or sometimes just understand it as the bank we have in mind.

So this sentence most naturally means:

• we’ll go to the bank

It usually refers to a specific bank or the bank relevant to the situation, not just any random bank.

الاجتماع is usually pronounced roughly like:

• el-egtimāʿ

A few helpful points:

• الـ is often pronounced el-
• the ج in Egyptian Arabic is pronounced like g in go
• so اجتماع sounds closer to egtimāʿ, not ijtimāʿ as in many other varieties

So the full phrase:

• اول ما الاجتماع يخلص might sound roughly like:
• awwal ma el-egtimāʿ yikhlas

It is usually pronounced roughly as:

• yikhlas

Important details:

• the first vowel is often i, so yi-
• the خ is the throaty sound written kh
• the stress is usually near the end: yikh-LAS or YIKH-las, depending on how narrowly you transcribe it

So:

• الاجتماع يخلص ≈ el-egtimāʿ yikhlas

Yes, but the meaning changes slightly.

• اول ما الاجتماع يخلص = as soon as the meeting ends
• بعد ما الاجتماع يخلص = after the meeting ends

اول ما emphasizes immediacy: right after it ends.
بعد ما is more general: sometime after it ends.

So if you want the idea of immediately after, اول ما is the better choice.

The given word order is very natural:

• اول ما الاجتماع يخلص، هنروح البنك

You can also reverse the two clauses:

• هنروح البنك اول ما الاجتماع يخلص

This still means the same thing:

• We’ll go to the bank as soon as the meeting ends

The version with اول ما... first often sounds especially natural when you want to set the time frame first.

It is clearly Egyptian Arabic.

The main clues are:

• هنروح for the future = Egyptian colloquial
• pronunciation and everyday usage of verbs like يروح
• the overall natural spoken structure

In Modern Standard Arabic, you would expect something more like:

• حالما ينتهي الاجتماع، سنذهب إلى البنك

So the meaning is the same, but the style is very different. The original sentence is natural spoken Egyptian.
