فيه شاي وقهوة في البيت.

Here فيه means there is / there are.

In Egyptian Arabic, فيه is very commonly used to introduce the existence of something:

• فيه شاي = There is tea
• فيه ناس = There are people

So in فيه شاي وقهوة في البيت, فيه is not the preposition in by itself. It is functioning as an existential expression: there is / there are.

In Arabic, the present tense often does not use a separate verb for to be the way English does.

So instead of saying something like There is tea and coffee in the house with an explicit is, Egyptian Arabic simply says:

• فيه شاي وقهوة في البيت

This is a very normal pattern. The idea of there is/are is carried by فيه.

Because they are doing two different jobs:

• فيه = there is / there are
• في البيت = in the house / at home

So even though both contain في, they are not the same thing in the sentence.

A helpful way to think about it:

• فيه = existential marker
• في = the normal preposition in

So the sentence structure is basically:

• There is
  • tea and coffee
    • in the house

Because in Egyptian Arabic, فيه is usually used as a general existential expression and does not change the way English is/are does.

So:

• فيه شاي = there is tea
• فيه شاي وقهوة = there is / there are tea and coffee
• فيه ناس = there are people

English forces you to choose is or are, but Egyptian Arabic usually just uses فيه in all these cases.

Because they are being mentioned as indefinite nouns: tea and coffee, not the tea and the coffee.

So:

• شاي = tea
• القهوة = the coffee
• قهوة = coffee

In this sentence, the speaker means that tea and coffee are available in the house, not that they are referring to specific already-known tea and coffee.

Also, with mass nouns like tea and coffee, English often also uses the bare noun in a similar way.

Usually it means that tea and coffee are available / present in the house.

Since شاي and قهوة are mass nouns here, the meaning is more like:

• There is some tea and some coffee at home
• Tea and coffee are in the house
• The house has tea and coffee

It does not automatically mean one cup of tea and one cup of coffee.

That is a very natural word order in Egyptian Arabic.

A common pattern is:

• فيه
  • thing(s) + place

So:

• فيه شاي وقهوة في البيت
• literally: There is tea and coffee in the house

This order sounds normal and natural. Arabic can sometimes move parts of the sentence around for emphasis, but this version is a standard everyday order.

It can mean either the house or home, depending on context.

In a sentence like this, English speakers will often translate it more naturally as:

• There is tea and coffee at home

But a more literal translation is:

• There is tea and coffee in the house

So في البيت can often be understood idiomatically as at home.

A common pronunciation is:

• fīh shāy wi-ʔahwa fil-bēt

A few useful notes:

• فيه = fīh
• شاي = shāy
• و is often pronounced wi before the next word
• قهوة in Egyptian is commonly pronounced ʔahwa
• في البيت often sounds like fil-bēt

So learners often hear the sentence almost like:

• fīh shāy wi-ʔahwa fil-bēt

In Egyptian Arabic, the usual negative existential is مفيش.

So:

• مفيش شاي وقهوة في البيت
• There isn’t tea and coffee in the house / There’s no tea and coffee at home

Very often, if you want to deny both items clearly, context will help. You could also separately mention them if needed.

The key contrast is:

• فيه = there is / there are
• مفيش = there isn’t / there aren’t / there is no

Not in natural English. Even though Arabic uses فيه for both singular and plural-style existence, English still has to sound natural.

Because tea and coffee are mass nouns, the best translations are things like:

• There is tea and coffee in the house
• There’s tea and coffee at home
• We have tea and coffee at home

So the Arabic is simple and flexible, but the best English translation depends on natural English usage.
