بالمكتبة مسموح نحكي بصوت واطي، بس مو مسموح نشغل موسيقى.

Because it is really two parts joined together:

• بـ = in / at
• المكتبة = the library

So:

• بـ + المكتبة = بالمكتبة

This kind of joining is very normal in Arabic. In Levantine, بـ is often used where English would say in or at.

You may also hear في المكتبة, but بالمكتبة sounds very natural in everyday Levantine.

Arabic has flexible word order, and starting with بالمكتبة sets the scene first: as for in the library...

That makes sense in a rule or instruction. It is a bit like saying:

• In the library, ...

So the sentence is organized by location first, then the rule.

مسموح means allowed / permitted.

In Levantine, it is commonly used in an impersonal way:

• مسموح نحكي = It’s allowed to speak
• مو مسموح نشغل موسيقى = It’s not allowed to play music

So even though مسموح is literally an adjective/participle, it often works like the English idea it is allowed.

This is a very common Levantine pattern.

After words like:

• مسموح = allowed
• ممنوع = forbidden
• لازم = must
• ممكن = possible

you usually use the bare imperfect verb, without بـ.

So:

• مسموح نحكي
• مو مسموح نشغل

not usually:

• مسموح منحكي
• مو مسموح منشغل

The بـ form is more for normal present/habitual statements, like:

• منحكي عربي = We speak Arabic
• منشغل الموسيقى = We turn on/play the music

Because Arabic does not use an infinitive in the same way English does.

English says:

• to speak
• to play

But Arabic often uses a normal verb form after words like مسموح.

So:

• مسموح نحكي literally uses we speak
• but in context it means to speak is allowed / it is allowed to speak

This is very normal and important to get used to in Arabic.

Because the verb already includes we.

In:

• نحكي
• نشغل

the prefix نـ shows first person plural: we.

So:

• نحكي = we speak / we talk
• نشغل = we turn on / we play

You can add نحنا for emphasis, but you do not need it:

• نحنا نحكي = we talk
  This sounds more emphatic, like we specifically.

Literally it is:

• بصوت = with/in a voice
• واطي = low

So بصوت واطي literally means in a low voice.

That is a very natural Levantine way to say:

• quietly
• softly
• in a low voice

واطي is a common colloquial word for low. A more formal alternative would be منخفض, but واطي is the everyday Levantine choice here.

Here بس means but.

So it connects two contrasting ideas:

• speaking quietly is allowed
• playing music is not allowed

Be careful: بس can also mean other things in other contexts, especially:

• only / just
• enough

But in this sentence, it clearly means but.

Yes — both مو مسموح and مش مسموح are common in Levantine.

Regional and personal preference affect which one people use more. In many Levantine varieties, both are understood and natural.

So these are both fine:

• مو مسموح نشغل موسيقى
• مش مسموح نشغل موسيقى

The meaning is the same: it’s not allowed to play music.

Good question, because شغل has several meanings.

In this sentence, نشغل means:

• turn on
• play
• put on

So:

• نشغل موسيقى = play music / put music on

It does not mean work music here.

Compare:

• شغل as a noun can mean work
• شغّل as a verb can mean turn on / operate / play

So context matters a lot with this root.

Yes, absolutely.

Both are natural:

• مو مسموح نشغل موسيقى = it’s not allowed to play music
• ممنوع نشغل موسيقى = playing music is forbidden / not allowed

ممنوع often sounds a bit more direct and is very common in rules, signs, and instructions.

So the original sentence is natural, but ممنوع would also be very common.

Yes, it sounds clearly Levantine or at least colloquial rather than Modern Standard Arabic.

Some dialectal clues are:

• نحكي for talk/speak — very common in Levantine
• واطي for low — colloquial
• مو for negation — colloquial
• the overall structure is conversational and natural for speech

In more formal Modern Standard Arabic, you would expect different wording, such as more formal vocabulary and often أن before the verb.

So this sentence is a good example of everyday Levantine usage.

Because the final ة (taa marbuuTa) is often pronounced -e in Levantine when pausing.

So:

• مكتبة → maktabe

This is one of the most noticeable pronunciation differences between Levantine and Modern Standard Arabic.

A few examples:

• سيارة → sayyāra or sayyāre, depending on dialect/context
• مكتبة → maktabe

So in this sentence, learners will often hear something like:

• bil-maktabe

rather than the more formal bil-maktaba.
