اختي بتسوق بسكليتة، بس انا بروح بالباص.

A rough pronunciation is:

ekhti bitsuuʔ basikleeta, bas ana بروح bil-baas

More neatly transliterated:

ekhti bitsūʔ basiklēta, bas ana brūḥ bil-bās

A few notes:

• اختي = ekhti / ikhti
• بتسوق = bitsūʔ or btsūʔ, depending on the speaker
• بسكليتة = basiklēta
• بروح = brūḥ
• بالباص = bil-bās

Pronunciation varies a bit across Levantine regions.

Because اخت means sister, and the ending -ي means my.

So:

• اخت = sister
• اختي = my sister

In more formal spelling, you may also see أختي. In casual Levantine writing, the hamza is often left out, so اختي is very common.

In Levantine Arabic, the prefix بـ often marks the present or habitual tense.

So:

• بتسوق = she drives / she rides
• بروح = I go

This is one of the most noticeable differences from Modern Standard Arabic. In MSA, you would not normally use this بـ prefix in the same way.

In Arabic verb conjugation, she in the present tense often takes تـ.

So:

• هو بيسوق = he drives
• هي بتسوق = she drives

That means بتسوق matches the feminine singular subject اختي.

Yes, that is normal in Levantine. The verb ساق / يسوق can be used for driving or riding vehicles, including a bicycle.

So بتسوق بسكليتة naturally means she rides a bicycle.

You may also hear other expressions in different varieties, such as using يركب in some contexts, but بتسوق بسكليتة is perfectly understandable and natural.

Here, بس means but.

So the sentence is structured like this:

• اختي بتسوق بسكليتة = My sister rides a bicycle
• بس انا بروح بالباص = but I go by bus

Be careful: بس can also mean only / just in other contexts. Here, the meaning is clearly but.

Yes, Arabic could simply say بروح, because the verb already tells you the subject is I.

But انا is included here for emphasis or contrast:

• My sister rides a bike,
• but I go by bus.

So انا helps make the contrast stronger. It sounds very natural in this kind of sentence.

Because بـ here means by or in.

So:

• الباص = the bus
• بالباص = by bus / on the bus

This is a very common pattern in Arabic for transportation:

• بالسيارة = by car
• بالتاكسي = by taxi
• بالباص = by bus

No, it is a borrowed word, and it is very common in spoken Levantine. It refers to a bicycle.

You may see or hear different forms, such as:

• بسكليتة
• بسيكليت
• بسكليت

In Modern Standard Arabic, a more formal word would be دراجة or دراجة هوائية, but in everyday Levantine, forms like بسكليتة are very common.

A more MSA-style version would be:

أختي تركب دراجة، لكنني أذهب بالحافلة.

Main differences:

• اختي becomes أختي
• بتسوق becomes تركب or possibly another formal verb depending on context
• بسكليتة becomes دراجة
• بس becomes لكن
• بروح becomes أذهب
• بالباص becomes بالحافلة

So the original sentence is clearly colloquial Levantine, not formal written Arabic.
