بعد الشغل رح مر عالبقالة قبل ما ارجع عالبيت.

Literally, بعد الشغل is after the work, but in natural English it means after work.

In Levantine, الشغل is a very common everyday word for work or job, so بعد الشغل is a very normal way to say after work.

Because شغل is the more everyday, colloquial word in Levantine for work / job.

So:

• الشغل = everyday spoken work
• العمل = more formal, more MSA-like, or more abstract depending on context

A native speaker would very naturally say بعد الشغل in casual conversation.

رح marks the future. It means something like will or going to.

So:

• رح مرّ = I’ll stop by / I’m going to stop by
• رح ارجع would mean I’ll return

In Levantine, رح is one of the most common future markers. You may also hear the shorter حـ in some speech.

In Levantine, the b- prefix usually marks the regular present tense:

• بمرّ = I pass / I’m passing / I usually pass by

But after a future marker like رح, that b- usually disappears:

• رح مرّ = I’ll stop by

So the sentence is following a very common Levantine pattern:

• present/habitual: بمرّ
• future: رح مرّ

Here مرّ عـ means to stop by, to pass by, or to swing by a place.

So رح مر عالبقالة does not just mean physically passing in front of the store. In this context, it usually means I’ll stop by the grocery store.

This is a very common colloquial use:

• مرّ عليّ = stop by me / come by my place
• مرّ عالمحل = stop by the shop

Because in spoken Levantine, على + ال is very often contracted to عالـ.

So:

• على البقالة → عالبقالة
• على البيت → عالبيت

This is extremely common in speech and in informal writing.

Yes, على often literally means on, but in Levantine it is used much more broadly than English on.

With some verbs, especially everyday motion expressions, على can correspond to English to, at, or by, depending on the phrase. With مرّ عـ, it is the normal preposition.

So:

• مرّ عالبقالة = stop by the grocery store
• ارجع عالبيت = go back home

You should learn these as natural verb + preposition combinations, not as word-for-word translations.

قبل ما means before when followed by a verb.

So:

• قبل ما ارجع = before I return / before I go back

The ما here is not a negation. It does not mean not in this sentence. It is just part of the expression قبل ما.

This is a very common structure in Levantine:

• قبل ما روح = before I go
• قبل ما ييجي = before he comes

Because after expressions like قبل ما, Levantine often uses the verb without the b- prefix.

Compare:

• برجع عالبيت = I go back home / I usually go back home
• قبل ما ارجع عالبيت = before I go back home

So just like رح often drops the b-, قبل ما also commonly takes the verb without b-.

Because Arabic usually does not need an explicit subject pronoun when the verb already shows the person.

Here the verbs already tell you the speaker is I:

• رح مرّ = I’ll stop by
• ارجع = I return / go back

So adding أنا is possible for emphasis, but it is not necessary. In normal speech, leaving it out is more natural.

In this sentence, عالبيت most naturally means home.

Literally it comes from على البيت, but in everyday Levantine:

• روح عالبيت = go home
• ارجع عالبيت = go back home

So even though بيت literally means house, the expression often corresponds to English home.

Because ش is a sun letter, so the l of ال assimilates to it.

So الشغل is pronounced more like ish-shughl or esh-shughl, not al-shughl.

That is a pronunciation rule you will hear all the time:

• الشغل → ish-shughl / esh-shughl
• الشام → ish-shaam / esh-shaam

Yes, it is clearly colloquial Levantine.

Some clues are:

• رح as a future marker
• الشغل as an everyday colloquial word
• contractions like عالبقالة and عالبيت
• the verb patterns without b- after رح and قبل ما

A more formal MSA-style sentence would be phrased differently, but this sentence sounds natural in spoken Levantine.
