Chữ ký của bạn ở đây.

Chữ ký means signature.

A rough breakdown is:

• chữ = writing, letters, script, characters
• ký = sign

But in modern Vietnamese, chữ ký is a fixed expression meaning a signature. You should learn it as one unit rather than translating each part separately every time.

Của marks possession, similar to of or 's in English.

So:

• chữ ký của bạn = your signature
• literally: signature of you

Vietnamese often forms possession like this:

• tên của tôi = my name
• xe của anh ấy = his car
• chữ ký của bạn = your signature

In everyday speech, của can sometimes be omitted in other phrases, but here chữ ký của bạn is very normal and clear.

Vietnamese often puts the main noun first, then the possessor after của.

So:

• chữ ký = signature
• của bạn = of you / your
• ở đây = here

Putting it together:

• Chữ ký của bạn ở đây.
• literally: Your signature here or The place for your signature is here

This is different from English, where your comes before signature.

Ở đây means here or at this place.

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

In many contexts, đây alone can already mean here, but ở đây sounds more explicitly locational.

So in this sentence:

• ở đây = here, in this spot

It tells you the location where the signature belongs.

Vietnamese often leaves out words that English requires, especially in short notices, labels, or simple directions.

English might say:

• Your signature goes here.
• Sign here.
• Your signature is here.

Vietnamese can simply say:

• Chữ ký của bạn ở đây.

This is natural in short written instructions because the intended meaning is understood from context. Vietnamese does not always need an explicit verb like English does.

It is more like a label or instructional note than a full command.

Depending on context, it can mean something like:

• Your signature here
• Put your signature here
• This is where your signature goes

So it is not a direct imperative in the way Ký tên ở đây is. It is more like the wording you might see next to a blank line on a form.

Not always. It works best as a form label or brief written prompt.

If you want to directly tell someone Sign here, more natural choices are:

• Ký tên ở đây. = Sign here.
• Xin ký vào đây. = Please sign here.
• Vui lòng ký ở đây. = Please sign here.

So:

• Chữ ký của bạn ở đây = suitable for a form or indicated signature area
• Ký tên ở đây = more direct instruction

They are related, but they are not the same grammar-wise.

• chữ ký = signature → a noun
• ký tên = to sign → a verb phrase

Examples:

• Tôi cần chữ ký của bạn. = I need your signature.
• Bạn hãy ký tên ở đây. = Please sign here.

So in your sentence, chữ ký is used because the sentence is talking about the signature itself, not the action of signing.

Yes. Bạn here means you, in a neutral and fairly friendly way.

Vietnamese pronouns depend a lot on relationship, age, and situation. In real life, other words might be used instead of bạn, for example:

• anh = you, for an older male / male peer in many contexts
• chị = you, for an older female / female peer in many contexts
• quý khách = valued customer, very polite/formal
• ông / bà = sir / madam, depending on context

So on a general form, bạn is understandable and common in modern neutral Vietnamese, but businesses may choose something more formal.

A rough word-for-word gloss would be:

• chữ ký = signature
• của = of
• bạn = you
• ở đây = here

So:

• chữ ký của bạn ở đây
• literally: signature of you here

A more natural English rendering would be:

• Your signature here
• Your signature goes here

A learner-friendly approximation is:

chữ ký của bạn ở đây
≈ chuh kee koo-a ban uh day

But Vietnamese pronunciation depends heavily on tones, so the tones matter a lot.

A rough tone guide:

• chữ = falling-rising tone
• ký = high rising tone
• của = falling-rising tone
• bạn = low heavy tone
• ở = falling-rising tone
• đây = level/high tone

A more standard Northern-style pronunciation in IPA is approximately:

• /cɨ˧˩˧ ki˦˥ kuə˧˩˧ ɓaːn˨˩ʔ ɤ˧˩˧ ɗɤj˧/

If you are learning, the most important thing is to notice that chữ and ký do not sound flat, and bạn has a short, heavy, stopped quality.

You could say other things, but they would mean something slightly different.

• chữ ký = the signature itself
• chỗ ký = the place to sign / signing spot

So:

• Chữ ký của bạn ở đây = Your signature goes here / your signature here
• Chỗ ký ở đây = The signing place is here / sign here area is here

If you specifically want to mark the line where someone should sign, more natural options include:

• Ký tên ở đây
• Chỗ ký tên
• Nơi ký tên

So yes, similar phrases exist, but they are not exact substitutes.

Yes. It depends on context.

It sounds fine when:

• it appears on a form
• it labels a blank line
• it points out where a signature belongs

It may sound less natural if spoken out loud as a normal sentence in conversation. In speech, people are more likely to say:

• Bạn ký ở đây nhé. = Sign here, okay.
• Xin ký tên ở đây. = Please sign here.
• Chị ký vào đây giúp em. = Please sign here for me.

So the sentence is most natural as a short written prompt, not as everyday conversation.
