سيبنا الاكل الباقي في التلاجة.

A common Cairene-style pronunciation is:

sibna l-akl il-bāʔi fit-talāga

A few useful notes:

• سيبنا → sibna
• الأكل → often l-akl or il-akl in connected speech
• الباقي → il-bāʔi, where ق is often pronounced as a glottal stop ʔ in Egyptian Arabic
• في التلاجة → often runs together as fit-talāga

So the whole sentence flows pretty smoothly as one unit.

Here سيبنا is the past tense, 1st person plural form of the Egyptian verb ساب / يسيب, meaning to leave.

So:

• سيبنا = we left

This is the Egyptian colloquial equivalent of something like MSA تركنا.

Because this is Egyptian Arabic, not Modern Standard Arabic.

In Egyptian speech, ساب / يسيب is the everyday verb for leave:

• ساب = he left
• سيبت = I left
• سيبنا = we left

ترك exists, but it sounds more formal or more MSA-like in many contexts.

Because الباقي is describing الأكل, and in Arabic adjectives usually match the noun in definiteness.

So:

• الأكل = the food
• الباقي = the remaining

Together:

• الأكل الباقي = the remaining food

If the noun is definite, the adjective normally has ال too.

الباقي literally means something like:

• the remaining
• what is left
• leftover

It comes from the idea of remaining/staying over.

So in this sentence, الأكل الباقي is naturally understood as:

• the remaining food
• the leftover food

التلاجة is the normal Egyptian colloquial form of the word.

In Modern Standard Arabic, the word is:

• الثلاجة

But in Egyptian Arabic:

• ث is very often pronounced as ت
• so ثلاجة becomes تلاجة

This is a very common sound change in Egyptian Arabic, and many people also write the colloquial pronunciation directly.

Because in natural speech, words connect.

What is written as:

• في التلاجة

is often pronounced more like:

• fit-talāga

This happens because:

• في ends in a vowel sound
• التلاجة begins with the definite article
• the whole phrase gets smoothed together in fast speech

So this is normal connected pronunciation, not a different grammar structure.

في means in or inside.

That makes it the natural preposition for something located in a fridge:

• في التلاجة = in the fridge

If something were on top of the fridge, you would more likely use:

• على التلاجة = on the fridge

Yes. Egyptian Arabic allows more than one word order.

The original:

• سيبنا الاكل الباقي في التلاجة

is a very natural verb-first sentence.

But you could also hear:

• إحنا سيبنا الأكل الباقي في التلاجة = We left the remaining food in the fridge
• الأكل الباقي سيبناه في التلاجة = The remaining food, we left it in the fridge

The basic meaning stays the same, but the emphasis changes.

It is grammatically singular, but it is a mass noun meaning food in a general sense.

So الأكل does not mean one food item. It means food as a substance/category, like:

• the food
• the leftover food

This is very normal in Arabic, just as food in English is usually not plural in this kind of sentence.

Yes, it can be.

Without vowels, سيبنا could potentially be read in different ways depending on context. For example, it can also look like an imperative expression involving us.

But in this sentence, the structure clearly supports the past-tense meaning:

• سيبنا الأكل الباقي في التلاجة = we left the remaining food in the fridge

So context removes the ambiguity.
