المنطقة المخصصة قرب المسار.

It is most naturally understood as a noun phrase, not a full sentence.

• المنطقة المخصصة = the designated/specified area
• قرب المسار = near the path/track

So the whole thing works like a label, caption, or sign text: the designated area near the path.

In everyday Arabic, especially on signs, notices, maps, and headings, it is very common to use a phrase instead of a full sentence.

A fuller sentence could be something like:

• المنطقة المخصصة قرب المسار. = The designated area is near the path.
  or
• هذه هي المنطقة المخصصة قرب المسار. = This is the designated area near the path.

The written form without a verb is completely normal in context.

Because المخصصة is an adjective describing المنطقة, and Arabic adjectives normally agree with the nouns they describe in:

• definiteness
• gender
• number
• case (in fully inflected Arabic)

Since المنطقة is definite because it has الـ, the adjective must also be definite:

• المنطقة المخصصة = the designated area

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

• منطقة مخصصة = a designated area

So this matching is one of the most important adjective rules in Arabic.

Because المنطقة is a feminine singular noun, so the adjective must also be feminine singular.

• masculine: مخصص
• feminine: مخصصة

So:

• مكان مخصص = a designated place
• منطقة مخصصة = a designated area

The feminine ending here is ة.

It is a passive participle used adjectivally.

It comes from the verb:

• خصّص = to allocate, designate, specify, assign

The passive participle pattern of this form is:

• مُخَصَّص = designated / allocated / assigned

Its feminine form is:

• مُخَصَّصَة

So in this phrase, المخصصة literally means something like the designated or the allocated.

This is very common in formal Arabic:

• مقاعد مخصصة = designated seats
• غرفة مخصصة = a designated room
• منطقة مخصصة = a designated area

قرب here means near and functions like a noun of place / ظرف in this kind of expression.

In practice, learners can think of it as behaving a lot like near in English.

So:

• قرب المسار = near the path

This structure is very common in Arabic.

You will also often see another version:

• بالقرب من المسار = near the path

Both are correct, but they are built differently:

• قرب المسار = a shorter, more compact expression
• بالقرب من المسار = a very common explicit prepositional expression

Because قرب can directly take a following noun in an iḍāfa-like structure:

• قربَ المسارِ = near the path

So you do not need من after plain قرب in this usage.

But if you use the expression بالقرب, then من normally appears:

• بالقرب من المسار

So compare:

• قرب المسار = near the path
• بالقرب من المسار = near the path

Both are good Arabic. The second one may feel a little more explicit to many learners because it resembles a preposition + object structure more clearly.

Because the phrase is referring to a specific path/track: the path rather than a path.

So:

• قرب المسار = near the path
• قرب مسار = near a path

In Arabic, the noun after قرب can be definite or indefinite depending on the meaning you want.

Also, because المسار follows قرب in this structure, it is understood in a genitive relationship grammatically.

A fully vocalized version would typically be:

• المنطقةُ المُخَصَّصَةُ قربَ المسارِ

Grammatically:

• المنطقةُ — nominative
• المُخَصَّصَةُ — nominative adjective agreeing with المنطقة
• قربَ — accusative as an adverbial noun of place
• المسارِ — genitive after قرب in this construction

In normal everyday writing, these short vowels are usually not written, so you just see:

• المنطقة المخصصة قرب المسار

A careful MSA pronunciation is approximately:

• al-manṭiqatu al-mukhaṣṣaṣatu qurba al-masāri

Without full case endings, many learners will hear or say something closer to:

• al-manṭiqa al-mukhaṣṣaṣa qurb al-masār

A few useful pronunciation notes:

• ط in منطقة is an emphatic t
• ص in مخصصة is an emphatic s
• the middle consonant in مخصصة is doubled in the fully vocalized form: مُخَصَّصَة
• the final ة in منطقة and مخصصة is normally pronounced like -a in pause

Yes. In Arabic, descriptive adjectives normally come after the noun.

So:

• المنطقة المخصصة = literally the area the-designated

This is the normal order in Arabic, unlike English, where adjectives usually come before the noun:

• designated area

This is one of the basic word-order differences English speakers have to get used to.

Yes, absolutely.

• المنطقة المخصصة قرب المسار
• المنطقة المخصصة بالقرب من المسار

Both are correct.

Very roughly:

• قرب المسار is shorter and more compact
• بالقرب من المسار is slightly more explicit and often feels more natural in full prose

In signs, labels, and concise written Arabic, the shorter قرب المسار is especially natural.

You can change it, but the result may sound different in emphasis or style.

The most straightforward order here is:

• المنطقة المخصصة قرب المسار

If you move the location phrase earlier, for example:

• قرب المسار المنطقة المخصصة

that would usually sound less natural as a neutral phrase.

Arabic is somewhat flexible, but for a simple descriptive expression, the most normal pattern is:

• noun + adjective + location phrase

So for learners, the safest model is:

• المنطقة = noun
• المخصصة = adjective
• قرب المسار = adverbial/location phrase

No. It is not iḍāfa.

It is a regular noun + adjective combination.

Why not iḍāfa?

Because in an iḍāfa construction, the first noun usually does not take الـ unless it is definite through possession/context, and the second noun is another noun, not an adjective.

Compare:

• المنطقة المخصصة = the designated area
  This is noun + adjective

Versus an iḍāfa like:

• منطقةُ المدرسةِ = the school’s area / the area of the school

That is noun + noun in a possessive/genitive relationship.

So in your phrase:

• المنطقة = noun
• المخصصة = adjective

not iḍāfa.
