الخزان مليان.

A common Levantine pronunciation is il-khazzān malyān or el-khazzān malyān.

A few helpful points:

• خ sounds like the ch in German Bach or Scottish loch
• ال is usually pronounced il- or el- in Levantine
• خ is a moon letter, so the l in ال is pronounced clearly: il-kh...
• The stress is roughly khaz-ZAAN mal-YAAN

You may also notice that everyday Arabic writing often leaves out short vowels and sometimes other pronunciation details, so learners usually have to pick up the exact spoken form by hearing it.

الخزان means the tank or the reservoir.

Depending on context, it could be:

• a water tank
• a fuel tank
• a storage tank
• another kind of container/reservoir

The noun is خزان, and الـ makes it definite, so it becomes the tank.

Because in Arabic, the present-tense verb to be is usually omitted in simple sentences like this.

So:

• الخزان مليان literally looks like the tank full
• but it means The tank is full

This is a very normal Arabic sentence pattern. If you wanted a different tense, then a verb would appear, for example:

• كان الخزان مليان = The tank was full

Because مليان here is the predicate of the sentence, not a directly attached adjective inside the noun phrase.

Compare these:

• الخزان مليان = The tank is full
• الخزان المليان = the full tank

So in your sentence, مليان is saying something about الخزان. It is not forming one combined phrase with it.

مليان is very common and natural in Levantine spoken Arabic.

In Modern Standard Arabic, you are more likely to see:

• الخزان ممتلئ
• الخزان مليء

So الخزان مليان sounds colloquial and spoken, which is exactly what you would expect in Levantine.

In this sentence, مليان functions like an adjective meaning full.

It is the masculine singular form, which matches الخزان.

So the structure is basically:

• الخزان = the tank
• مليان = full

Together: The tank is full.

Yes. It changes to agree with the noun.

Common forms include:

• مليان = masculine singular
• مليانة = feminine singular
• مليانين = masculine plural, especially with people

Examples:

• القنينة مليانة = The bottle is full
• الشباب مليانين طاقة = The guys are full of energy

With non-human plurals in Levantine, you will often hear feminine singular agreement:

• الخزانات مليانة = The tanks are full

A very common Levantine version is:

• الخزان مش مليان

In some areas, especially in Syria, you may also hear:

• الخزان مو مليان

Both mean The tank is not full.

You can add the substance or thing after مليان.

For example:

• الخزان مليان مي = The tank is full of water
• الخزان مليان بنزين = The tank is full of gasoline

This direct pattern is very common in everyday Levantine.

Yes. This pattern is extremely common in Levantine: noun + predicate.

Examples:

• البيت كبير = The house is big
• الأوضة فاضية = The room is empty
• الشارع زحمة = The street is crowded

So الخزان مليان is a very typical and useful sentence type to learn.
