Nhân viên nhìn chữ ký.

Nhân viên means employee, staff member, or worker.

A few useful notes:

• nhân relates to person / human
• viên in this kind of word often helps form a noun for a person with a role

So nhân viên is a very common word for someone who works at a company, office, store, bank, etc.

In this sentence, it can mean:

• the employee
• an employee
• sometimes even employees, depending on context

Vietnamese often does not mark singular vs. plural unless it needs to.

Vietnamese usually does not use articles like English a / an / the.

So:

• Nhân viên can mean an employee, the employee, or employees
• chữ ký can mean a signature or the signature

The exact meaning depends on context.

For example:

• Nhân viên nhìn chữ ký.
  could be The employee looks at the signature
  or An employee looks at a signature

If you want to make something more specific, Vietnamese can add other words, such as:

• này = this
• đó / kia = that
• một = one / a certain

Examples:

• một nhân viên = an employee / one employee
• chữ ký này = this signature

Yes. This sentence follows the basic Subject + Verb + Object order:

• Nhân viên = subject
• nhìn = verb
• chữ ký = object

So it works very much like:

• The employee
  • looks at
    • the signature

That makes this sentence quite straightforward for English speakers.

Nhìn means to look, to look at, or to gaze at.

In this sentence, it means the employee is directing their eyes toward the signature.

Some nearby verbs are different:

• nhìn = look at
• xem = watch / examine / check / look at for information
• thấy = see
• nhìn thấy = see, be able to see

Examples:

• nhìn chữ ký = look at the signature
• xem chữ ký = examine/check the signature
• thấy chữ ký = see the signature

So nhìn is fine here, but if the idea is more like inspect the signature, xem might also be possible in some contexts.

In Vietnamese, many verbs do not need a separate preposition where English does.

English says:

• look at the signature

Vietnamese can simply say:

• nhìn chữ ký

So the idea of at is built into how nhìn works in this sentence.

Sometimes you may also hear:

• nhìn vào chữ ký

This adds vào, which can make the direction of looking feel more explicit, like look toward / look at. But in many simple sentences, nhìn chữ ký is perfectly natural.

Chữ ký means signature.

Literally, the parts are:

• chữ = writing, letter, script, written character
• ký = sign

Together, chữ ký means a person’s written signature.

It is a very common everyday term, especially in offices, banks, forms, contracts, and official documents.

Example:

• Tôi cần chữ ký của bạn. = I need your signature.

Yes, sometimes chữ ký can also mean autograph, depending on context.

Usually:

• in office or legal contexts, it means signature
• in celebrity or fan contexts, it can mean autograph

For example:

• chữ ký trên hợp đồng = signature on the contract
• xin chữ ký của ca sĩ = ask for the singer’s autograph

In your sentence, without extra context, most learners would understand it as signature.

You usually know from context.

By itself, nhân viên can refer to:

• an employee
• the employee
• employees

If Vietnamese wants to make plurality clearer, it can add words like:

• các nhân viên = the employees / employees
• những nhân viên = employees / some employees

So:

• Nhân viên nhìn chữ ký. = could be singular or plural
• Các nhân viên nhìn chữ ký. = clearly plural

This is very normal in Vietnamese.

No, not by itself.

Vietnamese verbs do not change form for tense the way English verbs do.
So nhìn stays nhìn whether the action is present, past, or future.

The time is usually understood from context or from time words such as:

• đã = past marker
• đang = ongoing action
• sẽ = future marker

Examples:

• Nhân viên đã nhìn chữ ký. = The employee looked at the signature.
• Nhân viên đang nhìn chữ ký. = The employee is looking at the signature.
• Nhân viên sẽ nhìn chữ ký. = The employee will look at the signature.

Without a time marker, the sentence is neutral and often understood as present or general description.

A rough pronunciation guide is:

• Nhân viên ≈ nyun vyeen
• nhìn ≈ nyeen with a falling tone
• chữ ký ≈ chy with a broken-rising tone + kee with a rising tone

A few tone notes:

• nhân: level
• viên: level
• nhìn: falling tone
• chữ: ngã tone
• ký: rising tone

A few sounds that may be tricky for English speakers:

• nh sounds a bit like the ny in canyon
• ư in chữ is a vowel that does not exist exactly in English
• tones matter, especially in nhìn, chữ, and ký

Yes, it is a natural and grammatical simple sentence.

It sounds like a basic statement:
The employee looks at the signature or An employee looks at the signature.

Depending on context, Vietnamese speakers might also say:

• Nhân viên xem chữ ký. = The employee checks/examines the signature.
• Nhân viên nhìn vào chữ ký. = The employee looks at the signature.

Your original sentence is still correct and natural, especially as a simple learning example.

You can add đang to show an action in progress:

• Nhân viên đang nhìn chữ ký.

This means:

• The employee is looking at the signature

So:

• nhìn = look
• đang nhìn = is looking

This is one of the most common ways Vietnamese marks an ongoing action.
