لا يخرج المرشد من المسار ولا من المنطقة المخصصة.

لا is the normal particle used to negate a present-tense verb in MSA.

So:

• يخرج = he leaves / he goes out
• لا يخرج = he does not leave / he does not go out

In this sentence, لا يخرج المرشد means the guide does not leave.

Grammatically, it is a statement, not a direct command.

• لا يخرج المرشد = the guide does not leave
• A direct command to a man would be لا تخرج = do not leave

However, in formal instructions, rules, or regulations, Arabic often uses a statement like this to express what is allowed or not allowed. So depending on context, it can sound like a rule:

• The guide does not leave the path...
• In natural English, this may be understood as The guide must not leave the path...

Because this is a verbal sentence. In Arabic, it is very common for the verb to come first:

• يخرج المرشد = literally leaves the guide
• Natural English: the guide leaves

This verb-subject order is very normal in MSA.

You could also say:

• المرشد لا يخرج من المسار...

That is also correct, but it has a slightly different feel, since it begins with the subject.

يخرج is the imperfect (non-past) form of the verb خرج.

Here it is:

• 3rd person
• masculine
• singular

So it means:

• he leaves
• he goes out
• he exits

Because the subject is المرشد and that word is masculine singular, يخرج matches it.

The subject المرشد is singular, so the verb is singular too.

Also, in Arabic verbal sentences, when the verb comes before the subject, the verb is typically singular if the subject is singular.

Here:

• المرشد = the guide
• so يخرج = he leaves

If the subject were plural, Arabic has its own agreement patterns, but in this sentence everything is singular.

ولا here means and not or nor.

So the sentence structure is:

• لا يخرج المرشد من المسار
• ولا من المنطقة المخصصة

This gives the meaning:

• The guide does not leave the path, nor the designated area

In smoother English, we often translate it as:

• The guide does not leave the path or the designated area

So even though English often uses or after a negative, Arabic commonly uses ولا in this kind of structure.

Arabic often repeats the preposition with each item in a list, especially in formal writing.

So:

• من المسار
• ولا من المنطقة المخصصة

This is very natural Arabic.

In English, we often say:

• from the path or the designated area

without repeating from, but Arabic prefers to repeat it here.

That repeated من makes the structure clear and balanced.

Because both nouns are definite:

• المسار = the path / the route
• المنطقة = the area

This suggests that the speaker is talking about a specific path and a specific designated area, not just any path or any area.

Without الـ, the meaning would be more like a path or an area, which would sound different.

Because it is an adjective describing المنطقة, and المنطقة is a feminine noun.

In Arabic, adjectives agree with the noun they describe in:

• gender
• number
• definiteness

So:

• المنطقة = feminine, singular, definite
• المخصصة must also be feminine, singular, definite

That is why it is المخصصة, not المخصص.

المخصصة is an adjective modifying المنطقة.

So:

• المنطقة = the area
• المخصصة = designated / assigned / allocated

Together:

• المنطقة المخصصة = the designated area

This is a standard Arabic noun + adjective pattern, where the adjective comes after the noun.

Because only المنطقة is being described by المخصصة.

So the sentence means:

• from the path
• and not from the designated area

The adjective belongs only to the second noun phrase.

If Arabic wanted to say the designated path, it would need a separate adjective after المسار, such as المسار المخصص.

With full case endings, the sentence would be:

لا يخرجُ المرشدُ من المسارِ ولا من المنطقةِ المخصصةِ

Breakdown:

• يخرجُ: verb in the indicative
• المرشدُ: subject, so nominative
• المسارِ: after من, so genitive
• المنطقةِ: after من, so genitive
• المخصصةِ: adjective matching المنطقة, so also genitive

In normal Arabic writing, these short vowels are usually omitted.

Yes, that is also correct.

The difference is mainly in structure and emphasis:

• لا يخرج المرشد... = verbal sentence, very natural in formal Arabic
• المرشد لا يخرج... = starts with the subject, which can feel slightly more topic-focused

Both are grammatical. The original version sounds very natural for formal instructions or regulations.

Yes. يخرج comes from the root خ ر ج, which is associated with the idea of going out, exiting, or leaving.

From this root, you get forms like:

• خرج = he went out / he left
• يخرج = he goes out / he leaves
• خروج = خروج = exit / departure

Learning roots is very helpful in Arabic because many related words come from the same three consonants.

Yes, depending on context, المرشد can mean:

• guide
• leader
• advisor
• mentor

But in a sentence about staying within a path or designated area, guide is the most likely meaning.

So the exact English word depends on the situation, even though the Arabic grammar stays the same.
