مبارح مريت من قدام الجامعة وشفت اخي.

It is mostly colloquial Levantine.

Clues that it is colloquial:

• مبارح for yesterday
• مريت for I passed
• من قدام for in front of / past

The spelling اخي is a casual written form of أخي. That part is not especially un-Levantine, but in everyday speech some speakers might prefer forms like أخوي or خيّي, depending on the region.

مريت means I passed or I went past/by.

The -ت ending marks first person singular in the past tense, so it tells you the subject is I.

A fuller spelling is often مرّيت, but in casual writing people frequently leave out details like the shadda. So:

• مرّيت / مريت = I passed

In speech, the exact pronunciation can vary a bit by region.

Literally, من قدام means from in front of.

But in natural English, in a sentence like this, it usually means:

• past
• by
• in front of

So مريت من قدام الجامعة is naturally understood as I passed by the university or I passed in front of the university.

Because in many Levantine dialects, the letter ق is not pronounced like Classical Arabic q.

Common possibilities:

• a glottal stop sound, like ء
• sometimes a weakened sound in fast speech

So قدّام is very often pronounced something like ʔoddām in Levantine speech, even though it is still written with ق.

Because the conjunction و meaning and attaches directly to the next word in Arabic writing.

So:

• و + شفت → وشفت

This is normal Arabic spelling. The و is not a separate written word here.

It mainly means and, but in storytelling it often also gives a sense of then or and then.

So the sentence has a natural sequence:

1. I passed by the university
2. and then I saw my brother

Arabic often uses و very freely in narration this way.

In casual Arabic writing, people often leave out the hamza and other spelling details.

So:

• أخي = more careful spelling
• اخي = casual everyday spelling

They both represent my brother, pronounced roughly akhi.

It is understandable and common enough, especially in writing, but spoken Levantine has regional alternatives.

You may also hear:

• أخوي
• خيّي in some areas, especially Lebanese
• أخي in some contexts

So the sentence is fine, but a more colloquial version in some regions might use أخوي instead.

Because الجامعة means the university, referring to a specific university.

Without الـ, جامعة would usually sound more general:

• a university
• university in a broader sense

Here, the speaker is talking about a known place, so الجامعة is natural.

The word order can change. Arabic is quite flexible.

Putting مبارح first is very natural because it sets the scene right away:

• مبارح مريت من قدام الجامعة وشفت اخي

But other orders are possible for different emphasis, for example:

• شفت اخي مبارح = stronger focus on I saw my brother
• مبارح شفت اخي = time first, then the main event

So مبارح does not have to come first, but it is a very common placement.

A rough Levantine-style pronunciation could be:

mbāreḥ mrēt / marrēt men ʔoddām il-jāmʿa w shuft akhī

A few notes:

• مبارح → mbāreḥ
• مريت may vary a bit by region
• من قدام is often heard as men ʔoddām
• الجامعة often sounds like il-jāmʿa
• وشفت → w shuft
• أخي → akhī

Exact pronunciation depends on whether the speaker is Syrian, Lebanese, Palestinian, Jordanian, and so on.

Yes. Depending on the region, you might also hear:

• مبارح مرقت من قدّام الجامعة وشفت أخوي
• مبارح مريت من قدّام الجامعة وشفت أخوي

Using مرقت instead of مريت is very common in some Levantine varieties, and أخوي can sound more conversational than أخي.
