قبل ما نطلع، لازم نشوف الخريطة لانه طريق الفندق جديد علينا.

In Levantine, قبل ما + verb is the normal way to say before [someone does something].

So:

• قبل ما نطلع = before we leave / before we head out

Here, ما is not a negation word. It is just part of the pattern قبل ما when a verb follows.

Compare:

• قبل الظهر = before noon
• قبل ما نوصل = before we arrive

After قبل ما, Levantine usually uses the bare imperfect verb, without the بـ prefix.

So you normally say:

• قبل ما نطلع
• قبل ما توصل
• قبل ما يبلّش

This is because the action is still pending and tied to the clause introduced by قبل ما. Using بنطلع here would sound off in most Levantine speech.

For the same general reason: after لازم (must / have to / need to), Levantine normally uses the bare imperfect too.

So:

• لازم نشوف = we need to see / check
• لازم نروح = we have to go
• لازم تحكي معه = you need to talk to him

The بـ prefix is usually not used after لازم in this structure.

Not exactly. In everyday Levantine, شوف often means more than just passive see. It can mean:

• look at
• check
• take a look at

So لازم نشوف الخريطة is very naturally understood as:

• we need to check the map
• we should look at the map

Yes—طلع is a very flexible verb in Levantine.

Depending on context, it can mean things like:

• go up
• come out
• go out
• head out
• leave

In قبل ما نطلع, the natural meaning is before we head out / before we leave.

So this is a good example of how Levantine uses طلع more broadly than the basic dictionary meaning go up.

لانه means because.

In more careful spelling, you will often see لأنه. In casual writing, people very often drop the hamza and write لانه.

Both represent the same word here:

• لأنه / لانه = because

Pronunciation varies a bit by region, but something like laanno or laʔanno is common.

This is an iḍāfa structure, often called a construct phrase:

• طريق الفندق

Literally, it is something like road of the hotel, but in natural English here it means:

• the road to the hotel
• the way to the hotel

In an iḍāfa:

• the first noun usually does not take ال
• the whole phrase becomes definite because the second noun is definite

So even though it is طريق and not الطريق, the whole phrase طريق الفندق is definite because of الفندق.

This part is a nominal sentence, which is very common in Arabic.

• طريق الفندق = the subject
• جديد علينا = the predicate

Arabic usually does not use a present-tense verb for is in sentences like this. So:

• طريق الفندق جديد علينا literally = the road to the hotel new to us naturally = the road to the hotel is new to us

Also, جديد does not take ال here because it is a predicate adjective, not an adjective inside the noun phrase.

Compare:

• طريق الفندق جديد علينا = the road to the hotel is new to us
• طريق الفندق الجديد = the new road to the hotel

Because طريق is being treated as masculine here, which is very normal in Levantine.

So:

• طريق ... جديد

You may sometimes encounter feminine agreement with طريق in other contexts or in more formal Arabic, but جديد is completely natural here.

علينا is:

• على = on
• نا = us

So literally, جديد علينا is new on us, but the real meaning is:

• new to us
• unfamiliar to us

This is a very natural Arabic way to express that something is not familiar.

For example:

• هاي الفكرة جديدة عليّ = this idea is new to me
• المنطقة جديدة علينا = the area is new to us
