فريقنا ضد الفريق التاني.

A common Levantine-style pronunciation is:

farīʔna dedd il-farīʔ it-tāni

A few useful notes:

• فريقنا = farīʔna or sometimes farīqna, depending on whether the speaker turns ق into a glottal stop.
• ضد is often heard as something like dedd or didd, depending on region and speaker.
• الفريق is il-farīʔ.
• التاني is pronounced it-tāni, because the l of ال assimilates to t.

In Arabic, the verb to be is usually omitted in the present tense.

So Arabic literally says something like:

our team against the other team

But the natural English meaning is:

Our team is against the other team
or in a sports context, Our team is playing against the other team.

This is completely normal in both Levantine and Standard Arabic.

-نا means our.

So:

• فريق = team
• فريقنا = our team

Arabic often shows possession by attaching a suffix directly to the noun, instead of using a separate word like our before it.

Because فريقنا is already definite.

When you add a possessive suffix like -نا (our), the noun automatically becomes specific/definite:

• فريق = a team / team
• فريقنا = our team

So الفريقنا would be incorrect.

Because التاني is describing الفريق, and Arabic adjectives agree with the noun in definiteness.

So:

• الفريق التاني = the other team
• فريق تاني = another team or a second team

If the noun has ال, the adjective usually has ال too.

It can mean either second or other, depending on context.

In this sentence, the most natural meaning is the other:

• الفريق التاني = the other team

That is very common in spoken Levantine. In contexts where there are only two teams, the second team and the other team often amount to the same thing.

التاني is the common colloquial Levantine form.
الثاني is the Standard Arabic form.

In many Levantine everyday words, ث becomes ت in speech, so:

• Standard Arabic: الثاني
• Levantine: التاني

Both relate to the same basic meaning, but التاني sounds natural in spoken Levantine.

Yes. ضد is a very common way to say against.

It can be used:

• in sports: Team A against Team B
• in opinions: I’m against this idea
• in conflicts or opposition generally

In this sentence, it most naturally means versus.

Most likely, yes, because team against team strongly suggests sports or competition.

But grammatically, it could also fit other situations, like:

• a debate
• a game
• a contest
• a quiz competition

So the structure itself is general; the context tells you exactly what kind of against is meant.

Not if you mean against.

مع means with, not against.

So:

• فريقنا ضد الفريق التاني = Our team is against the other team
• فريقنا مع الفريق التاني = Our team is with the other team

That changes the meaning completely.

A more formal version would usually be:

فريقنا ضد الفريق الثاني

The main difference is:

• Levantine: التاني
• Standard Arabic: الثاني

In everyday spoken Levantine, التاني is the natural choice.
