الشقق مختلفة.

A useful learner pronunciation is:

ash-shuqaq mukhtalife

A few notes:

• الش is pronounced ash-sh or ish-sh, not al-sh
• In many Levantine accents, ق is often pronounced as a glottal stop, so the first word may sound closer to ish-shu’aʔ
• مختلفة is often heard as mukhtilfe or mukhtalfe in everyday Levantine speech

So the exact sound depends on the region, but the written sentence is the same.

Because in Arabic, present-tense sentences like this usually do not use a separate word for is/are.

So:

الشقق مختلفة
literally looks like
the apartments different

but it means:

the apartments are different

This is very normal in both Levantine and Standard Arabic.

If you wanted the past, you would usually add a form of كان:

كانت الشقق مختلفة = the apartments were different

This is one of the most important grammar patterns in Arabic:

Non-human plural nouns are very often treated grammatically as feminine singular.

Since الشقق means the apartments and apartments are non-human, the adjective comes in the feminine singular form:

• الشقق مختلفة
• البيوت كبيرة
• الكتب جديدة

So even though the meaning is plural in English, the adjective is often feminine singular in Arabic.

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

Here the structure is:

• الشقق = the subject, the apartments
• مختلفة = the predicate, different

So the sentence means:

The apartments are different

In Arabic, predicate adjectives are usually indefinite, so they do not take ال here.

These mean different things:

• الشقق مختلفة = The apartments are different
• الشقق المختلفة = the different apartments

So:

• without ال on مختلفة, it is a full sentence
• with ال on المختلفة, it becomes a noun phrase

This is a very common contrast in Arabic.

The singular is:

شقة = an apartment / a flat

The plural is:

شقق = apartments

This is a broken plural, which means Arabic changes the internal shape of the word instead of just adding a simple ending.

That is very common in Arabic vocabulary.

The final ة is called taa marbuuTa.

In this sentence, because the word comes at the end and you pause on it, in Levantine it usually sounds like:

-e

So مختلفة is often pronounced something like mukhtilfe or mukhtalfe.

In more careful Standard Arabic-style reading, it is usually -a:

mukhtalifa

And when grammar requires it in connected speech, ة can sound like -t.

Because ش is a sun letter.

With sun letters, the l sound in ال disappears in pronunciation and the next consonant is doubled.

So:

• written: الشقق
• pronounced: ash-shuqaq or ish-shu...

You still write ال, but you do not pronounce it as al-sh...

The writing works perfectly in both Levantine and Standard Arabic.

What changes most is the pronunciation, not the basic grammar.

Shared features here:

• no present-tense are
• non-human plural with feminine singular adjective
• same spelling

Levantine-style differences often include:

• ق becoming a glottal stop
• final ة sounding like -e
• some vowels being reduced in everyday speech

So this sentence is a good example of something that is natural and understandable in both.
