اخويا ركب اوتوبيس امبارح.

In Egyptian Arabic, اخويا (often also written أخويا) is the everyday colloquial way to say my brother.

• أخ / اخ = brother
• -يا here gives the sense of my

So the whole word means my brother.

This is different from Modern Standard Arabic, where you would usually say أخي. Egyptian often uses forms like:

• أخويا = my brother
• ابويا = my father
• أمِّي / أمي or أمّيا in some speech patterns = my mother

So this is a normal Egyptian colloquial form, not a mistake.

A good rough pronunciation is:

akhūya rikib ōtobīs embāriḥ

A few sound notes:

• خ in اخويا is like the ch in German Bach or Scottish loch
• ركب is commonly pronounced rikib in Egyptian speech
• اوتوبيس is often pronounced ōtobīs or otobīs
• ح at the end of امبارح is a soft, breathy h-like sound, stronger than normal English h

So if you want a smooth reading:

akhūya rikib ōtobīs embāriḥ

Because this sentence is in Egyptian Arabic, not Modern Standard Arabic.

Egyptian Arabic differs from Standard Arabic in both:

• vocabulary
• grammar/forms
• spelling conventions in informal writing

For example:

• Standard Arabic: أخي
• Egyptian Arabic: أخويا / اخويا

Colloquial writing is also less standardized, so people often write things the way they normally say them.

In informal Arabic writing, especially dialect writing, people often leave out hamza spelling details.

So:

• اخويا and أخويا both represent the same word
• the casual spelling without hamza is very common online and in texting

This does not usually change the meaning. It is mostly a matter of informal orthography.

All three are possible translations depending on context.

With transportation, ركب often means something like:

• got on
• rode
• took

So in this sentence, natural English translations could include:

• My brother rode a bus yesterday
• My brother got on a bus yesterday
• My brother took a bus yesterday

English usually prefers took a bus in everyday speech, but the Arabic verb itself is closer to the idea of riding/getting on the vehicle.

Because in Arabic, the verb ركب can take the vehicle directly as its object.

So Arabic says:

• ركب اوتوبيس

Literally, that is more like:

• rode a bus
• got on a bus

English usually wants a preposition in some contexts, but Arabic does not need one here.

Because here it is indefinite, so it means a bus, not the bus.

• اوتوبيس = a bus
• الأوتوبيس = the bus

That said, English and Arabic do not always use definiteness in exactly the same way. English often says take the bus in a general sense, but Arabic may still use an indefinite noun depending on what the speaker means.

In this sentence, the most straightforward reading is a bus.

Yes. اوتوبيس is a very common Egyptian word for bus.

It is a loanword, and you may also see the spelling:

• أتوبيس
• اوتوبيس

Both are common in colloquial writing.

So if you hear or see أتوبيس / اوتوبيس, that is completely normal Egyptian Arabic.

امبارح means yesterday in Egyptian Arabic.

It is colloquial, not the usual Modern Standard Arabic word. In Standard Arabic, the common word is:

• أمس = yesterday

In Egyptian, امبارح is the everyday spoken word. It is often pronounced something like:

embāriḥ or imbāriḥ

So this sentence sounds natural and conversational.

Because putting time expressions at the end is very common and natural in Egyptian Arabic.

So:

• اخويا ركب اوتوبيس امبارح

is a normal neutral sentence.

You can also move امبارح earlier for emphasis:

• امبارح اخويا ركب اوتوبيس

That would mean the same basic thing, but it puts more focus on yesterday.

Because subject–verb–object order is very common in Egyptian Arabic.

So:

• اخويا ركب اوتوبيس امبارح

is completely natural.

A verb-first version is also possible:

• ركب اخويا اوتوبيس امبارح

But in everyday Egyptian speech, starting with the subject is extremely common, especially in simple statements.

Because the verb tells you the subject is he, but it does not tell you which he.

So:

• ركب اوتوبيس امبارح = He took/got on a bus yesterday
• اخويا ركب اوتوبيس امبارح = My brother took/got on a bus yesterday

The noun اخويا identifies the person clearly.

Because this is Egyptian colloquial Arabic, and colloquial Arabic does not use the full case-ending system of Modern Standard Arabic in normal speech.

So you do not get endings like:

• -un
• -an
• -in

in ordinary Egyptian speech.

That is why the sentence looks simpler than a formal Standard Arabic sentence. This is one of the big differences learners notice when moving from Standard Arabic to dialect.
