Nhân viên kiểm tra đặc điểm nhận dạng.

• nhân viên = employee, staff member
• kiểm tra = check, inspect, verify
• đặc điểm = feature, characteristic
• nhận dạng = identification, recognition

So đặc điểm nhận dạng means identifying features or distinguishing characteristics.

It follows a very common Vietnamese pattern:

Subject + Verb + Object

• Nhân viên = subject
• kiểm tra = verb
• đặc điểm nhận dạng = object

So the sentence is literally:

Staff member checks identifying features.

This word order is quite similar to English.

Vietnamese usually does not require articles like the or a/an.

So nhân viên could mean:

• a staff member
• the staff member
• sometimes even staff in a general sense

The exact meaning depends on context. Vietnamese often leaves definiteness unstated unless it needs to be made clear.

For example:

• một nhân viên = a staff member
• nhân viên đó = that staff member
• các nhân viên = the staff members / staff members

By itself, nhân viên is usually understood as singular or generic, depending on context.

This sentence most naturally sounds like:

• The staff member checks the identifying features, or
• A staff member checks identifying features

If you want to make plural explicit, you could say:

• các nhân viên kiểm tra... = staff members check...

If you want to make singular explicit:

• một nhân viên kiểm tra... = one/a staff member checks...

Vietnamese verbs do not change form for tense the way English verbs do.

So kiểm tra by itself does not specifically mark present tense. The sentence could mean:

• a present action
• a habitual action
• a general statement
• an instruction, depending on context

If needed, Vietnamese can add time words or particles:

• đã kiểm tra = checked / has checked
• đang kiểm tra = is checking
• sẽ kiểm tra = will check

So:

• Nhân viên đang kiểm tra đặc điểm nhận dạng.
  = The staff member is checking the identifying features.

Kiểm tra is a very common verb meaning:

• to check
• to inspect
• to examine
• to verify

The best English translation depends on context.

In this sentence, it likely means something like:

• check
• verify
• inspect

For example, in an airport, hospital, police, or administrative setting, kiểm tra often suggests an official or procedural check.

This is a very common Vietnamese pattern.

• đặc điểm = characteristic / feature
• nhận dạng = identification / recognizing identity

Together, đặc điểm nhận dạng means identifying characteristics or distinguishing features.

Vietnamese often places the main noun first and then adds another word or phrase after it to narrow the meaning.

So the structure is roughly:

đặc điểm + nhận dạng
= features for identification
= identifying features

In English, we often reverse or reshape this relationship when translating.

On its own, nhận dạng can be understood as a verb meaning identify / recognize, or as a noun-like element related to identification.

In đặc điểm nhận dạng, it functions like a modifier describing what kind of features they are:

• features used for identification
• identifying features

This flexibility is normal in Vietnamese. A word can often behave more like a noun, verb, or modifier depending on where it appears.

Yes, it sounds natural, especially in formal or procedural contexts such as:

• security checks
• police work
• hospital intake
• immigration
• administrative processing

It has a slightly official, matter-of-fact tone.

In everyday casual conversation, a speaker might add more detail, such as whose identifying features are being checked:

• Nhân viên kiểm tra đặc điểm nhận dạng của khách hàng.
  = The staff member checks the customer’s identifying features.

The sentence does not explicitly say whose features they are. Vietnamese often leaves information unstated when it is obvious from context.

So đặc điểm nhận dạng could refer to:

• a person’s identifying features
• identifying marks on a document
• distinguishing characteristics of an object or suspect

If you want to specify it, you can add của:

• Nhân viên kiểm tra đặc điểm nhận dạng của hành khách.
  = The staff member checks the passenger’s identifying features.

• Nhân viên kiểm tra đặc điểm nhận dạng của đối tượng.
  = The staff member checks the subject’s identifying features.

Here are some common expansions:

• Một nhân viên kiểm tra đặc điểm nhận dạng.
  = A staff member checks the identifying features.

• Nhân viên đang kiểm tra đặc điểm nhận dạng.
  = The staff member is checking the identifying features.

• Nhân viên kiểm tra các đặc điểm nhận dạng của khách hàng.
  = The staff member checks the customer’s identifying features.

• Nhân viên kiểm tra giấy tờ và đặc điểm nhận dạng.
  = The staff member checks the documents and identifying features.

These versions can sound clearer because they add number, aspect, or ownership.

Yes, a few things:

1. Don’t expect articles
   Vietnamese often omits a/the.

2. Don’t expect tense on the verb itself
   kiểm tra stays the same whether the action is present, past, or future unless extra words are added.

3. Modifiers often come after the noun
   đặc điểm nhận dạng is not word-for-word like English. Vietnamese builds the phrase in its own way.

4. Meaning depends heavily on context
   The sentence is grammatically complete, but English usually wants more explicit information, such as who is being checked and when.
