Đội này rất giỏi.

In Vietnamese, demonstratives like này (this) usually come after the noun.

So:

• đội này = this team
• literally: team this

This is a very common Vietnamese pattern:

• nhà này = this house
• người này = this person
• xe này = this vehicle / this car

So even though English says this team, Vietnamese says team this.

Đội means team in this sentence.

It is commonly used for:

• sports teams
• work teams
• groups organized for a task or purpose

Depending on context, đội can sometimes also mean a squad or unit, but here it simply means team.

Rất means very.

It goes before an adjective to strengthen it:

• rất giỏi = very good / very skilled / very talented

This is one of the most common ways to form very + adjective in Vietnamese.

Examples:

• rất đẹp = very beautiful
• rất nhanh = very fast
• rất tốt = very good

Giỏi usually means good at something, skilled, talented, or excellent.

In Đội này rất giỏi, it means the team is very capable or very good.

A useful nuance:

• tốt often means good in a broad sense
• giỏi often emphasizes ability or skill

So:

• Đội này rất tốt can sound more general
• Đội này rất giỏi focuses more on skill or performance

Yes, from an English point of view, you can think of it that way.

Vietnamese often does not use a word equivalent to is/are in simple adjective sentences.

So:

• Đội này rất giỏi.
• literally: This team very skilled.

But in natural English, that becomes:

• This team is very good/skilled.

This is normal in Vietnamese. Adjectives can directly describe the subject without a separate to be verb.

The structure is:

• Đội này = subject noun phrase
• rất giỏi = predicate describing the subject

So the pattern is:

noun + demonstrative + degree word + adjective

In this sentence:

• đội = team
• này = this
• rất = very
• giỏi = skilled / good

So the sentence is built very simply: this team + very + skilled

Yes, absolutely.

• Đội này giỏi. = This team is good / skilled.
• Đội này rất giỏi. = This team is very good / very skilled.

So rất just adds intensity.

In everyday speech, Vietnamese sometimes even uses adjectives without any extra degree word, especially when the meaning is already clear.

Đội is pronounced roughly like doi with a falling-glottalized tone on the vowel.

A few pronunciation points:

• đ is like English d
• plain d in Vietnamese is a different sound, depending on dialect
• ội is a vowel combination, somewhat like oy in English boy, but not exactly the same

Tone matters a lot here, so it is best learned by listening to native audio.

Also remember:

• đ and d are different letters in Vietnamese
• đội and a similar-looking word with d would not be pronounced the same

Này has the huyền tone, which is a low falling tone.

So it is not flat. The voice drops.

This matters because tone changes word identity in Vietnamese. If you use the wrong tone, listeners may misunderstand you or need extra context to figure out what you mean.

Yes, it is completely natural.

It is short, direct, and very common in style. Vietnamese often prefers compact sentences like this.

Depending on context, a native speaker might also say things like:

• Đội này giỏi lắm. = This team is really good.
• Đội này rất mạnh. = This team is very strong.
• Đội này chơi rất giỏi. = This team plays very well.

But Đội này rất giỏi is already a perfectly normal sentence.

Yes, giỏi can describe different kinds of ability depending on context.

It can mean:

• good at a subject
• skilled at an activity
• talented in general
• sometimes clever or capable

For example:

• Cô ấy giỏi toán. = She is good at math.
• Anh ấy rất giỏi. = He is very capable / talented.

In Đội này rất giỏi, because the subject is a team, the natural interpretation is that the team is skilled or very good in performance.

Yes.

A common opposite is đó or kia, depending on context:

• đội này = this team
• đội đó = that team
• đội kia = that team over there / that other team

These small differences can depend on distance, contrast, and speaking style.

So if you want to change this team to that team, you would usually change này to đó or kia.

Because đội itself is already a noun meaning team. You do not need a separate classifier here just to say this team.

Vietnamese classifiers are common, but they are not used in every noun phrase.

For example:

• đội này = this team

That is already complete and natural.

A classifier would be more relevant in patterns involving numbers or certain noun types, but not every noun must have one in every sentence.
