يوجد خوف كبير هنا.

Here, يوجد means there is or there exists.

So:

يوجد خوف كبير هنا = There is great fear here.

Literally, يوجد comes from a verb related to being found/existing, so the sentence has a sense like A great fear exists here or Great fear is present here.

In English, we often say there is or there are. Arabic does not copy that structure exactly.

Instead, Arabic often uses:

• يوجد = there is / there exists
• or sometimes no verb at all in similar contexts, depending on the sentence

So يوجد خوف كبير هنا is a very normal MSA way to say that something exists in a place.

خوف means fear.

In this sentence, it is the thing that exists:

• يوجد = there is
• خوف = fear
• كبير = great/big
• هنا = here

So خوف is the main noun being described.

Because the sentence is introducing the existence of fear, not referring to a specific previously known fear.

Compare:

• خوف = fear / a fear
• الخوف = the fear

After يوجد, Arabic often uses an indefinite noun when introducing something new:

• يوجد رجل هنا = There is a man here
• يوجد خوف كبير هنا = There is great fear here

If you said يوجد الخوف هنا, it would sound much less natural in most contexts, because it would mean something more like the fear is here/present here, referring to a specific fear already known from context.

Because adjectives usually come after the noun in Arabic.

So:

• خوف كبير = great fear / big fear

This is the normal Arabic order:

• noun first
• adjective second

Compare:

• بيت كبير = a big house
• رجل طويل = a tall man
• خوف كبير = great fear

Arabic adjectives agree with the noun they describe in things like:

• gender
• number
• definiteness

Here, خوف is:

• masculine
• singular
• indefinite

So the adjective must match it:

• خوف كبير

If the noun were feminine, singular, indefinite, the adjective would also be feminine:

• مشكلة كبيرة = a big problem

It can mean both, depending on context.

With something abstract like خوف (fear), كبير is often best understood as:

• great
• serious
• intense

So خوف كبير is more natural in English as:

• great fear
• a lot of fear
• intense fear

rather than the very literal big fear.

هنا means here.

It tells you the location of the fear:

• يوجد خوف كبير هنا = There is great fear here

So the full structure is:

• existence: يوجد
• thing existing: خوف كبير
• place: هنا

Yes, it could come earlier. Arabic word order is flexible.

The version you have:

يوجد خوف كبير هنا

is a very natural neutral order:
There is great fear here.

But you could also say:

هنا يوجد خوف كبير

This puts a bit more attention on here.

So:

• يوجد خوف كبير هنا = neutral, very natural
• هنا يوجد خوف كبير = more emphasis on the location

A careful fully vowelled reading would be:

يُوجَدُ خَوْفٌ كَبِيرٌ هُنَا

Transliteration: yūjadu khawfun kabīrun hunā

A learner should notice:

• خوف ends with -un if full case endings are pronounced
• كبير also ends with -un
• in normal pause, those final short vowels are often not pronounced in actual reading aloud

Yes, in this sentence the noun after it is singular, so that matches well.

But more importantly for a learner, you can think of يوجد as a fixed common MSA expression meaning there is / there exists.

For example:

• يوجد كتاب على الطاولة = There is a book on the table
• يوجد طلاب في الصف = There are students in the classroom

So even though English changes is/are, Arabic often keeps يوجد as a general existential expression.

Yes. In some contexts, Arabic can simply say:

هنا خوف كبير

This can also mean There is great fear here.

However, يوجد خوف كبير هنا is clearer and especially common in formal written Arabic, which makes it very useful for learners of Modern Standard Arabic.

It is very normal in Modern Standard Arabic and formal writing.

In everyday spoken Arabic, many dialects prefer other ways to express there is, often using words like في or dialect-specific forms.

So for MSA study, يوجد خوف كبير هنا is a good, standard sentence. It sounds formal-neutral rather than casual-dialectal.
