Tim itu menjadi juara.

• tim = team
• itu = that / the
• menjadi = to become
• juara = champion / winner

So the structure is:

• Tim itu = that team / the team
• menjadi juara = became champion / became the champion

A very natural gloss is: That team became the champion or The team became champion.

In Indonesian, demonstratives like ini and itu usually come after the noun.

So:

• tim itu = that team / the team
• buku ini = this book
• rumah itu = that house

This is normal Indonesian word order. English puts that before the noun, but Indonesian usually puts itu after it.

It can mean either, depending on context.

• that team if you are contrasting it with another team
• the team if the team is already known from context

Indonesian does not have a direct equivalent of the English article the, so itu often helps make a noun definite.

So tim itu can be understood as:

• that team
• the team in question

Menjadi means to become.

So Tim itu menjadi juara literally means:

• That team became champion

It shows a change into a new state or role.

Compare:

• Dia menjadi dokter. = He/She became a doctor.
• Anak itu menjadi dewasa. = That child became an adult.

So here, the team was not yet champion, and then it became champion.

Because menjadi and adalah do different jobs.

• menjadi = to become
• adalah = roughly is / are / was / were in more formal defining statements

So:

• Tim itu menjadi juara. = The team became champion.
• Tim itu adalah juara. = The team is the champion. / That team is the champion.

The first sentence talks about a change or result.
The second identifies the team as champion.

So adalah would change the meaning.

Indonesian does not use articles like a, an, and the the way English does.

So juara can mean:

• a champion
• the champion
• champion

The exact interpretation comes from context.

After menjadi, Indonesian often uses the bare noun naturally:

• menjadi juara = become champion / become the champion
• menjadi dokter = become a doctor
• menjadi presiden = become president

This is very normal.

Here, juara functions most naturally as a noun, meaning champion or winner.

So:

• menjadi juara = become champion

Indonesian words can sometimes behave flexibly, but for a learner, it is best to understand juara here as a noun used after menjadi.

Not by itself.

Indonesian verbs do not change form for tense the way English verbs do. Menjadi can mean:

• becomes
• became
• has become depending on context.

So Tim itu menjadi juara could refer to present, past, or even future in the right context, though it is often understood as past or completed if the context is about a competition result.

If you want to make time clearer, Indonesian often adds a time word:

• Kemarin tim itu menjadi juara. = Yesterday that team became champion.
• Akhirnya tim itu menjadi juara. = Finally that team became champion.

Yes. Jadi is a very common shorter form in everyday speech.

• Tim itu menjadi juara. = more neutral / slightly more formal
• Tim itu jadi juara. = very natural, common, a bit less formal

Both are correct in many contexts.

Yes, but the meaning shifts a little.

• Tim itu menjadi juara. = That team became champion.
  This emphasizes the process or result of becoming champion.

• Tim itu juara. = That team is champion. / That team’s the champion.
  This identifies the team as champion, without focusing on the change.

So both are possible, but they are not exactly the same.

Tim is a loanword meaning team.

It is pronounced roughly like English team, but with Indonesian pronunciation:

• tim ≈ teem

The vowel is a clear ee sound.

Tim itu menjadi juara. is neutral and completely standard Indonesian.

• menjadi sounds normal and slightly more formal than jadi
• It would fit in news, writing, school materials, and careful speech

If you want a more casual version, Tim itu jadi juara is very common.

No, not in this sentence.

With objects and things like tim, itu is completely normal. It simply marks the noun as definite or points to a specific one.

For people, Indonesian can sometimes prefer names, titles, or other wording depending on context, but for tim, tim itu is perfectly natural.

The pattern is:

• Subject + verb + complement

So:

• Tim itu = subject
• menjadi = verb
• juara = complement

You can compare it with:

• Dia menjadi guru. = He/She became a teacher.
• Mereka menjadi pemenang. = They became the winners.

This is a very common Indonesian structure.
