Đừng đùa ở đây.

Đừng is used to make a negative command, so it means don’t.

The basic pattern is:

đừng + verb

So:

• đừng đùa = don’t joke / don’t fool around

It is one of the most common ways to tell someone not to do something in Vietnamese.

Đùa usually means to joke, to kid, to fool around, or sometimes to mess around, depending on context.

In Đừng đùa ở đây, it could mean things like:

• Don’t joke around here
• Don’t fool around here
• Don’t mess around here

If you specifically want to say something as a joke, Vietnamese often uses:

• nói đùa = to joke / say jokingly

So đùa by itself can be a bit broader than just tell a joke.

Vietnamese often leaves out the subject when it is obvious from context.

In English, you usually need Don’t joke here with an understood you, but in Vietnamese this is very normal:

• Đừng đùa ở đây.

It already sounds complete.

If you want to specify who you are talking to, you can add a pronoun or kinship term, for example:

• Em đừng đùa ở đây. = Don’t joke around here.
• Các bạn đừng đùa ở đây. = You guys, don’t joke around here.

So the version without a subject is natural and common.

Ở đây means here or in/at this place.

• ở = at / in
• đây = this place / here

Together:

• ở đây = here

So the sentence literally has the structure:

• đừng = don’t
• đùa = joke / fool around
• ở đây = here

Vietnamese often keeps location phrases after the verb, so đùa ở đây is a normal word order.

Yes, ở can be a verb meaning to live or to stay, but here it is a preposition meaning at or in.

Compare:

• Tôi ở Hà Nội. = I live in Hanoi.
  Here ở acts more like live/stay in.

• Đừng đùa ở đây. = Don’t joke here.
  Here ở đây is just a location phrase meaning here.

So the function of ở depends on the sentence.

Yes, it is natural.

It sounds like a direct warning or instruction: Don’t joke around here.

Depending on tone and situation, it may sound:

• firm
• annoyed
• serious

If you want to make it softer, Vietnamese often adds particles such as:

• Đừng đùa ở đây nhé.
• Đừng đùa ở đây nha.

If you want to sound more formal or polite, you might say:

• Xin đừng đùa ở đây.

So the original sentence is natural, but fairly direct.

Not necessarily, but it is fairly blunt.

Vietnamese commands are often softened by:

• pronouns
• particles
• polite words

For example:

• Em đừng đùa ở đây nhé. = softer, more personal
• Xin đừng đùa ở đây. = more formal/polite

Without anything added, Đừng đùa ở đây. can sound strict, especially if said with a sharp tone. That is similar to English Don’t fool around here.

So whether it feels rude depends a lot on:

• your tone of voice
• who you are speaking to
• the situation

Sometimes, but you should be careful.

English play covers many ideas, while Vietnamese uses different verbs depending on the meaning.

• chơi = play, have fun, play a game
• đùa = joke, kid around, fool around, tease

So in this sentence, đùa is closer to:

• joke around
• mess around
• fool around

not usually play in the sense of playing a game.

These are related but not identical.

• đùa = to joke / fool around
  Broad and flexible.

• nói đùa = to joke, to say something jokingly
  More specifically about speech.

• đùa giỡn = to play around / horse around / fool around
  Often emphasizes behavior and physical playfulness more than just words.

So:

• Đừng đùa ở đây. = Don’t joke around here.
• Đừng nói đùa ở đây. = Don’t make jokes here.
• Đừng đùa giỡn ở đây. = Don’t fool around here.

The exact best translation depends on context.

Vietnamese word order is different from English.

A simple pattern here is:

đừng + verb + location

So:

• Đừng + đùa + ở đây

Vietnamese often puts place expressions after the verb:

• ăn ở đây = eat here
• ngồi ở đây = sit here
• đùa ở đây = joke around here

This is completely normal Vietnamese structure.

Usually no. You normally need ở before đây in this sentence.

• Đừng đùa ở đây. = correct
• Đừng đùa đây. = unnatural / incorrect

That is because ở đây functions as a location phrase meaning here.

There are cases where đây appears without ở, but not in this structure.

A rough guide is:

• Đừng: starts with đ, which is like an English d sound, not like English th or z
• đùa: again starts with đ
• ở and đây have their own tones, which matter a lot

A rough approximation for an English speaker is something like:

• dừng đùa ở đây

But that is only approximate. The tones are important:

• đừng has a heavy/falling tone
• đùa has a falling tone
• ở has a broken rising tone
• đây has a level/high tone

If your tones are wrong, people may still understand from context, but practicing them will make your speech much clearer.

Yes, in some contexts đùa can overlap with tease or kid around, especially if someone is not being serious.

But if you specifically mean tease someone, Vietnamese might use other expressions depending on the type of teasing.

So in most neutral contexts, Đừng đùa ở đây is better understood as:

• Don’t joke around here
• Don’t fool around here

rather than specifically Don’t tease here.

You can add extra words after the verb phrase.

For example:

• Đừng đùa ở đây nữa. = Don’t joke here anymore.
• Đừng đùa như vậy ở đây. = Don’t joke like that here.
• Đừng có đùa ở đây. = stronger, like Don’t be joking around here.

So the basic sentence can be expanded easily:

đừng + verb + extra information

That makes it a very useful pattern to learn.
