التكييف شغال بالغرفة.

In Levantine Arabic, the verb to be is usually not expressed in the present tense.

So:

• التكييف شغال = The AC is on / working
• literally: the AC working

This is completely normal in Arabic.
If you want past or future, then Arabic uses other forms:

• التكييف كان شغال = The AC was on
• التكييف رح يكون شغال = The AC will be on

شغال means something like:

• working
• running
• on
• operating

With machines and appliances, it often means switched on and functioning.

So with التكييف, شغال usually means:

• the AC is on
• the AC is running

You will hear شغال with many other things too:

• التلفزيون شغال = The TV is on
• الموتور شغال = The engine is running
• الإنترنت شغال = The internet is working

Both can be used, but they are not exactly the same in all contexts.

• التكييف often refers to air conditioning or the AC system
• المكيّف often refers more specifically to the air conditioner unit

In everyday speech, people may use either one depending on region and habit. So:

• التكييف شغال = The AC / air conditioning is on
• المكيّف شغال = The AC unit is on

A learner should recognize both.

بالغرفة is made of:

• بـ = in / at
• الغرفة = the room

Together:

• بـ + الغرفة = بالغرفة
• meaning: in the room

Arabic often attaches short prepositions directly to the following word. That is why it is written as one unit.

Other common examples:

• بالبيت = in the house
• بالمدرسة = at school
• بالسيارة = in the car / by car depending on context

Both بالغرفة and في الغرفة can mean in the room.

In Levantine, بـ is very common and often sounds more natural in everyday speech than في in many contexts.

So these are both possible:

• التكييف شغال بالغرفة
• التكييف شغال في الغرفة

The version with بـ is very colloquial and common.

A natural Levantine-style pronunciation would be close to:

• it-takyiif shaghghaal bil-ghurfe

A few notes:

• التكييف: the ال before ت is pronounced with assimilation, so it sounds like it- rather than al-
• شغال is often pronounced shaghghaal
• بالغرفة is often bil-ghurfe or bil-ghirfe, depending on region

The final ة in غرفة is pronounced like -e in Levantine speech, so:

• غرفة → ghurfe / ghirfe

Because التكييف is treated as a masculine singular noun, the predicate is also masculine singular.

So:

• التكييف شغال = masculine singular

If the subject were feminine, you would usually use شغالة:

• الغسالة شغالة = The washing machine is on
• السيارة شغالة = The car is running

This kind of agreement is very important in Arabic.

In this sentence, شغال behaves like an adjective / active participle, not a fully conjugated verb.

That is very common in Arabic. Active participles often express a current state:

• شغال = working / on
• قاعد = sitting
• واقف = standing
• نايم = sleeping

So التكييف شغال literally has the structure:

• the AC + working

But in natural English, you translate it as:

• The AC is on
• The AC is running

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

It starts with a noun:

• التكييف = the AC

Then it gives information about it:

• شغال بالغرفة = on / running in the room

This is a basic and very common pattern in Arabic for describing states:

• الجو حلو = The weather is nice
• الباب مفتوح = The door is open
• الأكل جاهز = The food is ready

So التكييف شغال بالغرفة fits a very normal Arabic structure.

In meaning, بالغرفة tells you where this state applies: the AC is on in the room.

In practice, English speakers can think of it as describing the whole situation:

• The AC is on in the room

It is not usually understood as the room’s AC in a possessive sense.
It is simply giving the location.

Usually, no. The most natural interpretation is:

• The AC is on
• The AC is running
• The AC is operating

If you wanted to emphasize that something functions properly, context would usually make that clearer. For example, if someone asks whether the AC is broken, شغال could mean it works.

So شغال can mean either:

• on / running
  or
• working properly

But in this sentence, most learners should understand it first as the AC is on in the room.

Yes. In fully marked spelling, it is often written شغّال.

In everyday Arabic writing, short vowels and many other marks are often omitted, and people may also omit the shadda. So you may see:

• شغال
• شغّال

Both represent the same word in normal informal writing.

Because both nouns are definite here:

• التكييف = the AC
• الغرفة = the room

This usually means the speaker has a specific AC and a specific room in mind, or both are already known from context.

Compare:

• تكييف شغال بغرفة would sound less natural in most everyday contexts and much less specific
• التكييف شغال بالغرفة sounds like the AC is on in the room

Arabic uses definiteness very regularly, so it is normal to see الـ on both nouns here.

It is understandable and acceptable, and it sounds quite natural. But depending on region and speaker, you might also hear:

• المكيّف شغّال بالغرفة
• المكيّف شغال بالأوضة in areas where أوضة is used for room
• التكييف شغال جوّا الغرفة = The AC is on inside the room

So the exact wording may vary, but the structure is very normal Levantine:

• noun + state + location

Yes, absolutely.

If everyone already knows which room you mean, you can simply say:

• التكييف شغال

That means:

• The AC is on
• The AC is running

Arabic often leaves out information that is already clear from context.
