يا ريتني حفظت النسخة عالكمبيوتر كمان، لاني حذفت الملف من التلفون وما انتبهت.

يا ريتني means if only I had... / I wish I had... and usually expresses regret.

• يا ريت = if only / I wish
• -ني = me

So يا ريتني is an idiomatic way to say I wish I had or if only I had.

In this sentence, it sets up a regret about something in the past.

Because in Levantine Arabic, يا ريت often takes the past/perfect form when you are regretting something that did not happen.

So:

• يا ريتني حفظت...
  = I wish I had saved...

Even though English uses had saved, Arabic simply uses the regular past form here.

It can mean either one, depending on context.

• حفظ = to memorize
• حفظ can also mean to save, especially in computer/digital contexts

Here, because the sentence talks about a copy, a computer, a file, and a phone, حفظت clearly means saved.

So حفظت النسخة here means I saved the copy.

النسخة means the copy or the version.

In this context, it most likely means:

• a copy of the file
• a saved version
• a backup copy

It does not necessarily mean a physical paper copy. In everyday Arabic, نسخة is often used for digital copies too.

عالكمبيوتر is the colloquial contracted form of على الكمبيوتر.

In Levantine speech:

• على
  • الـ often becomes عالـ

So:

• على الكمبيوتر → عالكمبيوتر

This is very common in spoken Arabic and in informal writing.

In natural English, you would usually translate it as on the computer.

So:

• حفظت النسخة عالكمبيوتر
  = saved the copy on the computer

Even though English sometimes thinks of this as movement (save it to the computer), Arabic commonly uses على here.

كمان means also, too, or as well.

Here it means the speaker wishes they had saved the copy on the computer too, not just kept it on the phone.

So it adds the idea of an additional place.

They are the same word: because I.

• لأني is the more standard spelling
• لاني is a very common informal spelling in dialect writing

In Levantine, people often do not write the hamza carefully in casual text. So لاني is completely normal in informal writing.

حذفت means I deleted.

It comes from حذف = to delete / remove.

The ending -ت marks first person singular past:

• حذفت = I deleted

This form is the same whether the speaker is male or female.

They are related, but not exactly identical.

• النسخة = the copy / the version
• الملف = the file

The speaker is saying they wish they had saved a copy/version on the computer, because they deleted the file from the phone.

In natural speech, people may switch between these kinds of words loosely, especially in tech situations.

Because من means from, and that fits the verb deleted.

• حذفت الملف من التلفون
  = I deleted the file from the phone

If you said عالتلفون, that would mean on the phone, which sounds more like location than removal.

So من is the natural choice here.

ما انتبهت literally means I didn’t pay attention, but in natural English it often means:

• I didn’t notice
• I didn’t realize
• I wasn’t paying attention

In this sentence, it suggests the speaker deleted the file and didn’t notice / didn’t realize what had happened.

The و simply means and.

So:

• حذفت الملف من التلفون وما انتبهت
  = I deleted the file from the phone and didn’t notice / realize

In Arabic, و is used very often to connect actions, sometimes more often than in English.

Both are common.

• التلفون = phone
• الموبايل = mobile phone

In everyday Levantine, many speakers would naturally say الموبايل here too:

• حذفت الملف من الموبايل

Both sound normal. The choice depends on the speaker and region.

No, it is clearly colloquial Levantine.

Some clues are:

• يا ريتني
• عالكمبيوتر
• كمان
• التلفون
• informal spelling like لاني
• no case endings

A more formal version would sound more like:

• يا ليتني حفظت النسخة على الكمبيوتر أيضًا، لأنني حذفت الملف من الهاتف ولم أنتبه.

But the original sentence is much more natural for everyday spoken Levantine.

A rough pronunciation would be:

ya rētni ḥfaẓet en-nuskha ʿal-kombyūter kamān, laʾanni ḥazaft el-malaf men et-telefōn w ma-ntabahet

Pronunciation varies by region, but a few useful things to notice are:

• عالكمبيوتر is said smoothly as one chunk
• لاني is often pronounced something like laʾanni
• ما انتبهت often runs together in speech

No. يا ريت can be used for wishes in general, not only past regret.

But in this sentence, because it is followed by a past verb, it expresses regret about the past:

• يا ريتني حفظت... = I wish I had saved...

In other contexts, يا ريت can express present or future wishes too.
