المشجعين المتحمسين احتفلوا بعد المباراة.

Because Arabic adjectives normally come after the noun they describe.

So:

• المشجعين المتحمسين = literally the fans the-enthusiastic
• natural English order = the enthusiastic fans

This is one of the biggest word-order differences between English and Arabic.

Because in Arabic, the adjective has to match the noun in definiteness.

Here, المشجعين means the fans, so the adjective must also be definite:

• المشجعين المتحمسين = the enthusiastic fans

If you removed الـ from both, you would get:

• مشجعين متحمسين = enthusiastic fans / some enthusiastic fans

So Arabic usually marks the on both the noun and the adjective, not just the noun.

This is a very common question, especially if you have seen formal Arabic.

In strict MSA, a sound masculine plural subject would normally be -ون, so you would expect:

• المشجعون المتحمسون احتفلوا

But in Levantine colloquial, case endings are not really used the way they are in MSA, and -ين is very commonly used in these plural forms.

So in this sentence:

• المشجعين
• المتحمسين

look more colloquial/Levantine-style than fully case-marked formal Arabic.

Because adjectives in Arabic have to agree with the noun they describe.

Here, المتحمسين matches المشجعين in:

• number: plural
• gender: masculine
• definiteness: both have الـ
• in more formal grammar, also case

So Arabic agreement is stronger than in English. You do not just say the fans enthusiastic with a fixed adjective form; the adjective changes to match the noun.

The ending -وا means they in the past tense.

So:

• احتفلوا = they celebrated

Arabic verbs usually include the subject inside the verb itself, so there is no need for a separate word meaning they.

That means the sentence is literally something like:

• the enthusiastic fans — they celebrated after the match

In natural English, we just say:

• The enthusiastic fans celebrated after the match.

Arabic allows more than one word order.

This sentence uses subject + verb order:

• المشجعين المتحمسين احتفلوا

That is common and natural, especially when you want to start by talking about the fans.

If you put the verb first in formal Arabic, the structure would usually be:

• احتفل المشجعون المتحمسون بعد المباراة

So English speakers often notice that Arabic can switch word order more freely than English.

It means after the match or after the game.

• بعد = after
• المباراة = the match / the game

So the whole phrase is a time expression telling you when they celebrated.

In formal grammar, بعد is followed by a genitive noun, but in everyday Levantine speech you usually do not hear the case ending.

It is understandable as Levantine, but it feels a bit mixed in register.

Why?

• The -ين plural forms fit colloquial Levantine better than strict MSA.
• Words like المباراة and the overall sentence structure are also perfectly normal in more standard-style Arabic.

This kind of mixing is very common in real life, especially in writing. People often write Arabic in a way that is not purely formal and not purely dialect either.

A broad Levantine-style pronunciation would be something like:

• el-mshajjaʿīn el-mutaḥammisīn eḥtafalo baʿd el-mbārāh

Exact pronunciation varies by country and city, but a few general points are:

• الـ is often pronounced el- or il-
• احتفلوا sounds like eḥtafalo / iḥtafalo
• بعد is baʿd

So even if the spelling looks formal, the spoken form can sound clearly Levantine.

For one male fan, you would say:

• المشجع المتحمس احتفل بعد المباراة

For one female fan, you would say:

• المشجعة المتحمسة احتفلت بعد المباراة

So the sentence changes in both the adjective and the verb to match the person you are talking about.
