خبر الشرطة.

If the meaning you were shown is he informed the police, the usual Levantine pronunciation is khabbar eš-šurṭa.

A few helpful points:

• خ sounds like the ch in German Bach or Scottish loch.
• ش is sh.
• ط is an emphatic t.
• الشرطة is pronounced eš-šurṭa because of sun-letter assimilation.

If the meaning were something like police news/report, then خبر would be read khabar instead of khabbar.

Because Arabic usually does not write short vowels, and in normal writing it may also leave out the shadda.

So خبر can represent different words, including:

• khabar = news
• khabbar = he informed / told

That is very normal in Arabic. You use context and the meaning you were given to know which reading is correct.

In Arabic, the verb itself often already tells you the subject.

So if خبر here is the verb khabbar, it already means he informed.
You do not need a separate word for he unless you want emphasis or contrast.

For example:

• هو خبّر الشرطة = he informed the police
  This sounds more emphatic than just خبّر الشرطة.

If this is the verb khabbar, it is past tense:

• خبّر الشرطة = he informed the police

Related Levantine forms:

• بيخبّر الشرطة = he tells / informs the police
• عم يخبّر الشرطة = he is informing the police

Because ش is a sun letter.

With sun letters, the ل of الـ is not pronounced. Instead, the next consonant is doubled.

So:

• written: الشرطة
• pronounced: eš-šurṭa

That doubled sh sound is important. You may also hear slightly different vowels, like iš-šurṭa, depending on the speaker and region.

No. خبّر can take the person directly as its object.

So:

• خبّر الشرطة = he informed the police

This is similar to English tell someone, not tell to someone.

If you want to add the topic, you can say something like:

• خبّر الشرطة عن الحادث = he informed the police about the accident

Because verb + object is a very normal word order in Arabic.

So خبّر الشرطة is a natural way to say he informed the police.

If you wanted to mention the subject too, you could say:

• خبّر الولد الشرطة = the boy informed the police

Levantine can also use subject-first order in many situations, but verb-first order is extremely common.

Grammatically, الشرطة is usually treated as a collective noun, often with feminine singular agreement.

So Arabic may say something equivalent to:

• إجت الشرطة = the police came

That can feel strange to English speakers, because English police behaves like a plural noun.

The spelling can be the same in both Levantine and Standard Arabic.

What changes most is the pronunciation and how formal it sounds:

• Levantine: khabbar eš-šurṭa
• More Standard-Arabic-style reading: khabbara ash-shurṭa

In everyday Levantine, people do not pronounce the formal case endings used in Standard Arabic.

The root is خ ب ر.

This root is connected with news, information, and knowing. That is why you see related words such as:

• خبر = news
• خبّر = inform / tell
• خبرة = experience

Learning roots is very useful in Arabic because it helps you connect vocabulary that looks different in English but belongs to the same word family.

In this word, the final ة is pronounced -a in normal pause, so you get shurṭa.

That is why الشرطة is pronounced eš-šurṭa.

In some other grammatical environments, the hidden t can reappear, but in this sentence you just hear the final -a sound.
