في السوبرماركت فيه ساندوتشات وبيض.

The first في means in or at.

So في السوبرماركت means in the supermarket or at the supermarket, depending on context. In Egyptian Arabic, في is a very common preposition for location.

Here, فيه means there is or there are.

In Egyptian Arabic, فيه is often used as an existential expression: it tells you that something exists somewhere.

So the pattern is:

في + place + فيه + thing(s)
= In/at + place, there is/are + thing(s)

Even though فيه can literally mean in it in other contexts, that is not how it works here.

Because they do two different jobs:

• في السوبرماركت = gives the location
• فيه = says that something exists there

So the sentence structure is basically:

In the supermarket, there are ...

This is completely normal in Egyptian Arabic.

In Arabic, the present tense often does not use a separate verb for is/are the way English does.

In this kind of sentence, فيه handles the idea of there is / there are, so you do not need another verb.

That is why the sentence can feel a little strange to an English speaker at first: Arabic is building the idea differently.

Yes. السوبرماركت is a borrowed word from English.

This is very common in Egyptian Arabic, especially for modern everyday items and places. You will often hear borrowed words adapted to Arabic pronunciation.

Also, because it has الـ attached, it means the supermarket.

Because س is a sun letter.

When الـ comes before a sun letter, the l sound assimilates. So السوبرماركت is pronounced more like:

es-supermarket
or
is-supermarket

rather than el-supermarket.

This is a very common pronunciation rule in Arabic.

Because -ات is a very common plural ending in Arabic, especially for:

• borrowed words
• many non-Arabic nouns
• some Arabic nouns as well

So:

• ساندوتش = sandwich
• ساندوتشات = sandwiches

You may also see slightly different spellings for this word, since loanwords are not always written in only one fixed way.

بيض is commonly used in Egyptian Arabic as a collective / mass noun meaning eggs.

So instead of thinking of it as a normal English-style plural, it is better to think of it as a word that refers to eggs in general.

Useful related form:

• بيضة = one egg

So:

• بيض = eggs
• بيضة = an egg

This kind of singular/collective relationship is very common in Arabic.

Because they are indefinite here.

After فيه, nouns often appear without الـ when the meaning is something like:

• there are some sandwiches
• there are eggs

If you added الـ, it would sound more like you mean specific, known sandwiches and eggs:

• الساندوتشات
• البيض

So without الـ, the sentence sounds more natural for introducing items that are simply present there.

Yes. In spoken Egyptian Arabic, فيه is commonly used for both:

• there is
• there are

So you do not need a separate plural form the way English does.

For example:

• فيه كتاب = there is a book
• فيه كتب = there are books

This is one of the nice simplifications in spoken Arabic.

In Egyptian Arabic, و is usually pronounced more like we or wi, not like formal Arabic wa.

So وبيض is often pronounced something like:

we bēḍ
or
wi bēḍ

The exact vowel can vary a bit by speaker and speed, but it usually will not sound like a careful formal wa.

A rough Egyptian-style pronunciation would be:

fi s-supermarket fīh sandweshāt we bēḍ

A few notes:

• في = fi
• السوبرماركت = es-/is-supermarket because of the sun-letter rule
• فيه = fīh
• ساندوتشات may sound like sandweshāt or something close, depending on speaker
• بيض in Egyptian is often pronounced bēḍ

You do not need perfect transliteration; the main goal is getting used to how Egyptian Arabic reduces and links sounds in natural speech.

Yes. Egyptian Arabic allows some flexibility.

For example, you could also hear something like:

فيه ساندوتشات وبيض في السوبرماركت

That also makes sense. The difference is mostly about focus and flow.

• في السوبرماركت فيه ... puts the location first
• فيه ... في السوبرماركت introduces the existence first, then gives the location

Both are natural, and learners should get used to both patterns.
