Đây là công việc toàn thời gian.

Đây usually means this or here, depending on context.

In Đây là công việc toàn thời gian, it means this:

• Đây = this
• là = is
• công việc toàn thời gian = a full-time job

So đây is pointing to something near the speaker, either physically or in the conversation.

You can think of đây là... as a very common pattern meaning this is...

Là is the Vietnamese linking verb, similar to to be in English when identifying or defining something.

So:

• Đây là công việc toàn thời gian = This is a full-time job

You often use là when one noun is being equated with another noun:

• Đây là giáo viên. = This is a teacher.
• Đó là nhà tôi. = That is my house.

However, Vietnamese does not use là in every situation where English uses is/am/are. For example:

• Tôi mệt. = I am tired.
  Not Tôi là mệt.

So in this sentence, là is correct because it connects this with a full-time job.

Công việc means job, work, or task, depending on context. In this sentence, it means job.

Both việc and công việc can refer to work, but công việc often sounds a bit more clearly like a job or employment-related work.

Compare:

• công việc = job, work
• việc = work, matter, task, thing to do

In many real-life situations, Vietnamese speakers might also say:

• Đây là việc toàn thời gian.

That is also understandable, but công việc toàn thời gian is especially clear if you want to mean a full-time job.

Toàn thời gian literally means something like all time or full time.

Breakdown:

• toàn = whole, entire, full
• thời gian = time

Together, toàn thời gian means full-time.

This is a fixed expression commonly used for jobs, study, and work schedules:

• làm việc toàn thời gian = work full-time
• nhân viên toàn thời gian = full-time employee
• công việc toàn thời gian = full-time job

The opposite is:

• bán thời gian = part-time

In Vietnamese, descriptive words and phrases often come after the noun, not before it like in English.

So:

• English: full-time job
• Vietnamese: công việc toàn thời gian

This is a very common word-order pattern:

• nhà lớn = big house
• xe mới = new car
• công việc toàn thời gian = full-time job

So even though full-time comes before job in English, in Vietnamese the modifier comes after the noun.

Vietnamese does not use articles like a, an, and the the way English does.

So:

• Đây là công việc toàn thời gian can mean This is a full-time job

If you want, you can add một:

• Đây là một công việc toàn thời gian.

That also means This is a full-time job.

The version without một is very natural. Vietnamese often leaves out words that English requires.

Very roughly:

• công việc = job / the job / a job, depending on context
• một công việc = one job / a job

Not necessarily. Both are correct, but they can feel slightly different.

• Đây là công việc toàn thời gian.
  Natural and straightforward. It identifies something as full-time work or a full-time job.

• Đây là một công việc toàn thời gian.
  Also natural, and it emphasizes that it is one full-time job or a full-time job.

In many contexts, Vietnamese prefers the version without một unless the speaker wants to stress the idea of one or introduce it more explicitly.

Yes. Depending on context, công việc can refer to job or work.

So this sentence could be understood as:

• This is a full-time job
• This is full-time work

If you are talking about employment status, a full-time job is probably the most natural English translation. But Vietnamese often leaves a little more room for context than English does.

A rough learner-friendly guide:

• Đây ≈ day (but with a Vietnamese tone)
• là ≈ lah
• công ≈ gong / kohng
• việc ≈ vee-etk or vee-uhk with a short, clipped ending
• toàn ≈ twahn
• thời ≈ somewhat like tuh-ee or thuhy, but this is hard to approximate in English
• gian ≈ zan or yan, depending on accent

A few important pronunciation notes:

• đ is like normal English d
• plain d in Vietnamese is different
• tones matter a lot, especially in đây, là, việc, thời

If possible, it is much better to learn this from audio than from English spelling approximations.

Yes, it is natural and correct.

A Vietnamese speaker might say it in contexts like:

• explaining a position in a company
• describing a job listing
• clarifying whether something is full-time or part-time

For example:

• Đây là công việc toàn thời gian, không phải bán thời gian.
  = This is a full-time job, not a part-time one.

So the sentence sounds normal and useful.

You would usually say:

Đây là công việc bán thời gian.

Breakdown:

• bán thời gian = part-time
• toàn thời gian = full-time

So:

• Đây là công việc toàn thời gian. = This is a full-time job.
• Đây là công việc bán thời gian. = This is a part-time job.

This is a very helpful pair to learn together.
