في ناس من كل العالم.

Here في means there is / there are, not in.

In Levantine, في is very commonly used as an existential word:

• في ناس = there are people
• ما في وقت = there isn’t time
• في مشكلة = there is a problem

So in this sentence, في ناس means there are people.

In Arabic, the verb to be is usually not expressed in the present tense.

So instead of saying something like there are people, Levantine often just says:

• في ناس

The word في already gives the idea of existence, so you do not need a separate verb like are.

Yes. في can also mean in.

The meaning depends on context:

• في البيت = in the house
• في ناس = there are people

A useful clue: when في comes at the start of a sentence and is followed by an indefinite noun like ناس, it often means there is/there are.

ناس means people.

It is a very common everyday word in Levantine and other Arabic varieties. It is a collective plural word, so it refers to people as a group.

Examples:

• الناس منيحة = people are nice
• في ناس هون = there are people here

It does not mean one person. For a person, you would use another word, such as شخص.

Because the sentence means there are people, not there are the people.

• ناس = people / some people
• الناس = the people

After existential في, Arabic often uses an indefinite noun:

• في كتاب = there is a book
• في سيارات = there are cars
• في ناس = there are people

If you said في الناس, that would sound much less natural in this meaning.

Literally, من كل العالم means from all the world.

In natural English, that becomes:

• from all over the world
• from around the world

So the phrase is:

• من = from
• كل = all / every
• العالم = the world

Together, it means from all over the world.

Because كل العالم means the whole world / all the world.

When كل is followed by a definite noun, it often means the whole entire thing:

• كل البيت = the whole house
• كل اليوم = the whole day
• كل العالم = the whole world

If you said كل عالم, that would mean something more like every world or could create confusion with other meanings of عالم. In this sentence, كل العالم is the natural phrase.

A natural Levantine pronunciation is roughly:

fii naas min kill il-ʕaalam

A few notes:

• في = fii
• ناس = naas
• من is often pronounced lightly, almost like min or mən
• كل may sound like kill or kell, depending on region
• العالم here means the world, pronounced roughly il-ʕaalam

So the whole sentence flows like: fii naas min kill il-ʕaalam

It is very natural in Levantine, but it would also be understood very widely across the Arabic-speaking world.

Why it feels Levantine/informal:

• using في for there is/there are is very common in spoken dialects
• there are no case endings
• the structure is simple and conversational

A more formal Modern Standard Arabic version might be:

• هناك أناس من جميع أنحاء العالم

But في ناس من كل العالم is exactly the kind of sentence you would hear in everyday speech.

Yes, the spelling العالم can represent different words depending on pronunciation.

Here it means the world:

• العالَم in formal Arabic
• roughly il-ʕaalam in Levantine speech

A different pronunciation gives the scholar/scientist:

• العالِم in formal Arabic

In this sentence, the context makes it clear that العالم means the world, because من كل العالم is a fixed, very common expression meaning from all over the world.

In Levantine, the most straightforward form is في ناس.

You may sometimes see or hear فيه in some dialects or informal writing, but that can also mean in him / in it, so for a learner, في ناس is the safest and clearest form to learn for there are people.

So for this sentence, stick with:

• في ناس من كل العالم

This order is the most natural, neutral one:

• في ناس من كل العالم

It starts with the existence idea (there are) and then tells you who those people are.

You could rearrange parts in special contexts for emphasis, but as a basic sentence pattern, this is the best one to learn:

• في
  • noun
• then extra information

So:

• في ناس = there are people
• في ناس من كل العالم = there are people from all over the world

In Levantine, you usually negate existential في with ما في:

• ما في ناس من كل العالم = There aren’t people from all over the world

More examples:

• في وقت = There is time
• ما في وقت = There isn’t time

So the negative pattern to remember is:

• في = there is / there are
• ما في = there isn’t / there aren’t
