ممكن تنتبه على اختي اليوم؟

A common Levantine-style pronunciation is:

momken tentebeh ʿa ekhti il-yom?

A few notes:

• ممكن is often pronounced momken or mumkin, depending on the speaker.
• على is very often shortened in speech to عَ / ʿa.
• أختي / اختي is often pronounced ekhti in Levantine.
• اليوم is commonly il-yom or just lyom in fast speech.

So in natural speech, it may sound quite compact: momken tentebeh ʿa ekhti lyom?

This is best understood as Levantine colloquial Arabic.

Why?

• The use of ممكن to make a request is very common in spoken dialect.
• The structure is conversational and natural for everyday speech.
• انتبه على in the sense of look after / keep an eye on is very colloquial.

In more formal Standard Arabic, someone might say something like: هل يمكنك أن تعتني بأختي اليوم؟

So the original sentence is very normal in speech, but not especially formal.

ممكن literally means possible.

At the start of a sentence, it often works like:

• can... ?
• could you... ?
• would it be possible to... ?

So it softens the request and makes it polite.

Compare:

• انتبه على أختي اليوم = Look after my sister today → more direct
• ممكن تنتبه على أختي اليوم؟ = Could you look after my sister today? → softer and more polite

In everyday Levantine Arabic, yes/no questions often do not need a separate question particle.

They are usually understood from:

• intonation
• context
• words like ممكن

So ممكن تنتبه على اختي اليوم؟ naturally sounds like a request/question.

In spoken Levantine, using هل would usually sound too formal or bookish for this kind of everyday sentence.

This is an important phrase to learn as a unit.

انتبه by itself can mean things like:

• pay attention
• notice
• be careful

But in Levantine, انتبه على + person often means:

• look after
• keep an eye on
• watch over

So:

• تنتبه على أختي = look after my sister / keep an eye on my sister

Why على? Because Arabic verbs often pair with prepositions in ways that do not match English directly. You should memorize:

انتبه على حدا = look after someone / watch someone carefully

Also, in speech, على is often reduced to عَ.

The subject is an understood you.

Arabic often does not need a separate pronoun like you because the verb form already gives that information.

Here, تنتبه is being understood as:

• you pay attention / you look after

So the sentence does not need إنت.

A learner should also know that this written form can be ambiguous in isolation:

• تنتبه can also look like she pays attention

But in this sentence, because it is a request directed at someone, it is naturally understood as you.

This is a very common learner question in Levantine.

In many Levantine contexts, بـ marks the regular present or habitual:

• بتفهم عربي = you understand Arabic
• بروح كل يوم = I go every day

But after words like ممكن, speakers often use the bare imperfect without بـ:

• ممكن تجي؟
• ممكن تساعدني؟
• ممكن تنتبه على أختي؟

So ممكن تنتبه sounds natural.

Using بتنتبه here would not be the usual way to make this polite request.

Yes — in careful spelling, it would normally be أختي.

But in informal writing, especially:

• texting
• chat messages
• social media
• casual dialect writing

people often leave out hamzas.

So:

• أختي = more careful spelling
• اختي = very common informal spelling

Both represent my sister.

The -ي is the attached pronoun meaning my.

So:

• أخت = sister
• أختي = my sister

This is a very common Arabic pattern:

• صديق = friend
• صديقي = my friend
• بيت = house
• بيتي = my house

So أختي is simply sister + my.

You change the verb to match who you are addressing.

To a man:

• ممكن تنتبه على أختي اليوم؟

To a woman:

• ممكن تنتبهي على أختي اليوم؟

To more than one person:

• ممكن تنتبهوا على أختي اليوم؟

So the rest of the sentence stays the same, but the verb changes.

Yes. Arabic has fairly flexible word order, especially in speech.

These are all possible:

• ممكن تنتبه على أختي اليوم؟
• ممكن اليوم تنتبه على أختي؟
• ممكن تنتبه اليوم على أختي؟

The original version sounds very natural. Putting اليوم at the end is a simple, common way to add the time after the main request.

Yes, it is natural and polite for everyday Levantine speech.

If you want to make it even softer, you could add something like:

• لو سمحت = please (to a man)
• لو سمحتي = please (to a woman)

For example:

• ممكن لو سمحت تنتبه على أختي اليوم؟
• لو سمحت، ممكن تنتبه على أختي اليوم؟

That sounds warm and natural when asking a favor.
