اذا الجو منيح السبت، منطلع عالجبل من الصبح ونرجع قبل المسا.

In Levantine Arabic, the verb to be is usually omitted in the present tense.

So:

• الجو منيح = the weather is nice
• literally: the weather nice

This is completely normal.
If you wanted the past or future, you would usually need a form of كان:

• الجو كان منيح = the weather was nice
• الجو رح يكون منيح = the weather will be nice

إذا means if for a real or possible condition.

So here:

• إذا الجو منيح السبت = If the weather is nice on Saturday

This suggests a normal, realistic possibility.

By contrast, لو is often used for more hypothetical, unlikely, or contrary-to-fact situations.

Compare:

• إذا الجو منيح، منطلع = If the weather is nice, we’ll go out
• لو الجو منيح، كنا طلعنا = If the weather had been nice, we would have gone out

So in this sentence, إذا is the natural choice.

منيح is a very common Levantine adjective meaning good, nice, fine, or well, depending on context.

Here, with weather, it means something like:

• nice
• good
• pleasant

So الجو منيح means the weather is nice.

This is colloquial Levantine, not Modern Standard Arabic. In MSA, you might expect something like:

• الجو جميل
• الطقس جميل

But in everyday Levantine, منيح is extremely common.

In Levantine Arabic, days of the week are often used without a preposition when giving time.

So:

• السبت = on Saturday / Saturday

That is very natural.

You can think of it as a time expression functioning by itself. English needs on, but Arabic often does not.

You may also hear:

• يوم السبت = on Saturday
• بالسبت in some dialect usage, though السبت by itself is very common

So إذا الجو منيح السبت is a normal way to say if the weather is nice on Saturday.

منطلع comes from the verb طلع.

In Levantine, طلع can mean things like:

• go up
• go out
• head off
• leave
• climb
• set out

Here, because the destination is the mountain, it has the sense of:

• we go up
• we head up
• we go

The مـ / نـ part here is part of the imperfect conjugation for we:

• منطلع = we go up / we head out

So the sentence uses a very natural colloquial verb for going up to the mountain.

No. In منطلع, the beginning is part of the verb conjugation, not the separate word من.

The verb is طلع. In the imperfect tense, Levantine adds prefixes:

• بطلع / بطلع = I go up or sometimes he goes up, depending on dialect and context
• بتطلع = you go up / she goes up
• منطلع = we go up
• بيطلع = he goes up

So منطلع is one single verb meaning we go up / we head out.

It is not:

• من + طلع

That would be a different thing entirely.

عالجبل is the colloquial contracted form of:

• على الجبل

In Levantine, على often becomes عَـ, especially before ال:

• على البيت → عالبيت
• على الجبل → عالجبل
• على المدرسة → عالمدرسة

So:

• منطلع عالجبل = we go up to the mountain

This contraction is extremely common in spoken Levantine.

من الصبح literally means from the morning.

In natural English, depending on context, it can mean:

• in the morning
• from early morning
• starting in the morning

In this sentence, it suggests they will leave or be there from the morning onward, not just at some vague point later in the day.

A few useful pieces:

• من = from
• الصبح = the morning

So:

• من الصبح = from the morning / starting in the morning

This is a very common colloquial time expression.

المسا is the common Levantine colloquial form of المساء.

So:

• المسا = the evening
• MSA: المساء

In everyday speech, Levantine often simplifies words compared with Standard Arabic, especially endings and hamza sounds.

So:

• قبل المسا = before the evening
• more naturally in English: before evening / before it gets late

This is very normal spoken dialect.

In Levantine Arabic, the imperfect/present form is often used for the future, especially when the future meaning is already clear from context.

Here the future is clear because of:

• إذا = if
• السبت = Saturday

So:

• منطلع = we’ll go up
• ونرجع = and we’ll come back

You could also say:

• رح نطلع
• ورح نرجع

But the version without رح is very natural, especially in conditionals and plans.

Because the verb itself already shows the subject.

In Arabic, subject pronouns are often omitted when the verb makes the subject clear.

So:

• منطلع already means we go / we’ll go
• ونرجع already means and we return / and we’ll return

You only add an explicit pronoun like نحنا if you want emphasis or contrast.

For example:

• نحنا منطلع، مو هني = We’re going, not them

But in a normal sentence, the verb alone is enough.

It means we return or we go back.

The verb is رجع = to return / go back / come back.

So:

• ونرجع قبل المسا = and we come back before evening

In English, come back sounds very natural here, because the idea is returning from the trip.

The و at the beginning simply means and:

• و + نرجع = and we return / and we come back

Yes, to some extent.

This sentence is natural, but Levantine often allows some flexibility with time expressions. You may also hear things like:

• إذا الجو منيح السبت، منطلع عالجبل
• إذا السبت الجو منيح، منطلع عالجبل
• إذا الجو منيح يوم السبت، منطلع عالجبل

All of these can work, though they may sound slightly different in emphasis.

The given version sounds like:

• If the weather’s nice Saturday, we’ll go up to the mountain...

So the word order is conversational and very typical of spoken dialect.

Yes, it sounds clearly Levantine. Some strong clues are:

• منيح for good/nice
• عالـ instead of full على الـ
• الصبح
• المسا
• the general spoken-style structure

A more Standard Arabic version would look quite different, for example:

• إذا كان الطقس جميلاً يوم السبت، سنصعد إلى الجبل صباحاً ونعود قبل المساء

That sounds formal and written.
The original sentence sounds like something people would actually say in everyday Levantine conversation.
