عزمت صحابي على الغدا قبل ما اروح البنك.

Here عزمت does not mean I was determined.

In Egyptian Arabic, عزم can mean to invite someone or to treat someone to food. So:

• عزمت صحابي على الغدا = I invited my friends to lunch
• It can also suggest I paid for the lunch / I treated them

So this is a very colloquial Egyptian use of عزم.

In this sentence, صحابي most naturally means my friends.

Why?

• صحاب = friends
• ـي = my

So صحابي = my friends

If you wanted my friend in Egyptian, you would usually say صاحبي.

A learner can easily confuse these two:

• صاحبي = my friend
• صحابي = my friends

You may also see أصحابي for my friends, but صحابي is very natural in Egyptian colloquial speech and writing.

Because this verb commonly follows the pattern:

عزم + person + على + food/meal/event

So:

• عزمت صحابي على الغدا
• literally something like I invited my friends on/for the lunch
• naturally in English: I invited my friends to lunch or I treated my friends to lunch

The preposition على is part of the normal Arabic pattern here. It is not translated literally as on.

Here it means lunch.

That is a very common point of confusion for learners.

In Egyptian Arabic:

• الغدا = lunch
• بكرة = tomorrow

So in this sentence, على الغدا clearly means for lunch / to lunch, not for tomorrow.

Because this is colloquial Egyptian writing.

In more formal Arabic, lunch is often written:

• الغداء

But in everyday Egyptian writing, people often simplify spelling, especially in chats and informal text, so you will very often see:

• الغدا

The same thing happens later in the sentence with:

• اروح instead of the more careful spelling أروح

So the sentence is written in a normal informal Egyptian style.

قبل ما means before followed by a verb/clause.

So:

• قبل ما أروح البنك = before I go to the bank / before I went to the bank

This is a very common Egyptian structure. Compare:

• بعد ما = after

Egyptian Arabic usually prefers قبل ما + verb rather than trying to copy an English pattern like before going.

Because in Egyptian Arabic, verbs of motion often take the destination directly.

So:

• أروح البنك = go to the bank
• literally it looks like go the bank

This is completely normal in Egyptian. English requires to, but Egyptian Arabic often does not in this kind of sentence.

Because after expressions like قبل ما, Egyptian Arabic normally uses the imperfect form of the verb, even when the overall meaning is past.

So:

• عزمت صحابي على الغدا قبل ما أروح البنك

can be understood as:

• I invited my friends to lunch before I went to the bank

The main verb عزمت is past, and that makes the whole sentence feel past in context.

Also, in casual writing:

• اروح = informal spelling
• أروح = fuller spelling

They mean the same thing here.

A rough pronunciation would be:

ʿazamt saḥābi ʿal-ghada abl ma arūḥ el-bank

A few useful notes:

• على is often pronounced more like ʿa or ʿal
• قبل is often pronounced abl
• البنك is pronounced el-bank
• the sound ع does not have a real English equivalent

So in natural fast speech, it may sound smoother and more connected than the spelling suggests.

That is normal Arabic usage.

Arabic often uses the definite article in places where English would not. So:

• على الغدا literally looks like on the lunch
• but naturally it means to lunch or for lunch

So you should not translate الـ word-for-word every time. In many expressions, it is just part of how Arabic says it naturally.
