المقعد جنب الكشك فاضي.

It is a nominal sentence in the present tense.

• المقعد جنب الكشك = the subject phrase
• فاضي = the predicate adjective

So the sentence is built like:

[the seat next to the kiosk] + [empty]

A very literal word-for-word breakdown would be:

• المقعد = the seat
• جنب = beside / next to
• الكشك = the kiosk
• فاضي = empty / vacant / free

Because in Levantine Arabic, present-tense sentences like this usually do not use a verb meaning is/am/are.

So instead of saying:

the seat next to the kiosk is empty

Arabic simply says:

the seat next to the kiosk empty

This is completely normal.

If you want other tenses, then a verb appears:

• كان فاضي = it was empty
• رح يكون فاضي = it will be empty

جنب means beside, next to, or by.

In this sentence, جنب الكشك means next to the kiosk.

It often behaves like a preposition in everyday speech, even though historically it is related to the noun side. For a learner, the easiest way to treat it is:

• جنب + noun = next to + noun

Examples:

• جنب البيت = next to the house
• جنب الباب = next to the door

Because Arabic can often attach a short location phrase directly to a noun without needing a relative word like that.

So:

• المقعد جنب الكشك = the seat next to the kiosk

This is natural and compact.

You may also hear longer forms in speech, especially if the phrase is more complex, but here اللي is not necessary.

Because فاضي here is the predicate of the sentence, not an adjective inside the noun phrase.

Compare these two:

• المقعد فاضي = the seat is empty
• المقعد الفاضي = the empty seat

This is a very important Arabic pattern:

• definite noun + indefinite adjective often makes a full sentence
• definite noun + definite adjective makes a noun phrase

So in your sentence, فاضي means is empty, not the empty.

Because المقعد is masculine singular, and the adjective agrees with it.

So:

• masculine singular: فاضي
• feminine singular: فاضية

For example:

• الغرفة فاضية = the room is empty
• المقعد فاضي = the seat is empty

Not always. فاضي is a very common word in Levantine and can mean several related things depending on context:

• empty
• vacant
• unoccupied
• free / available

With a seat, it usually means:

• empty
• available

With a person, it can mean:

• free
• not busy

For example:

• أنا فاضي اليوم = I’m free today

مقعد is understandable and correct, but in everyday Levantine, كرسي is often more common when talking about a chair or seat.

Still, مقعد works well for seat, especially in slightly more formal or written-style Arabic, or when you want the idea of a seat rather than specifically a chair.

So a learner should recognize مقعد, but also know that كرسي is extremely common in daily speech.

A common Levantine-style pronunciation would be roughly:

el-maqʿad janb el-koshk faaDi

A few notes:

• ال is usually pronounced el- or il-, not the careful MSA-style al-
• ق may be pronounced differently depending on region and speaker:
  • some keep it as q
  • many urban speakers pronounce it like a glottal stop, a brief catch in the throat
• فاضي has a long faa-
• the ض in فاضي is a deep, emphatic d sound

So pronunciation can vary, but the sentence remains the same.

In Levantine, the usual way is to use مش before the adjective:

المقعد جنب الكشك مش فاضي.

That means:

The seat next to the kiosk is not empty.

This is the most useful everyday pattern:

• هو فاضي = it is empty / he is free
• هو مش فاضي = it is not empty / he is not free

Usually, you just use intonation:

المقعد جنب الكشك فاضي؟

That means:

Is the seat next to the kiosk empty?

In everyday Levantine, you normally do not need a separate word like do or is at the beginning. The rising intonation does the job.
