Việc này gây nhiều vấn đề.

Việc này means something like this matter, this issue, this thing, or this situation, depending on context.

• việc = a matter, task, affair, piece of business
• này = this

So Việc này is not always literally this job. In many contexts, it is broader and can refer to this whole matter or what we’re dealing with right now.

In Vietnamese, demonstratives like this and that usually come after the noun.

So:

• việc này = this matter
• vấn đề này = this problem
• người này = this person

This is the normal Vietnamese word order, even though in English we say this matter.

gây means to cause, to create, or to bring about, usually with a negative result in sentences like this.

In Việc này gây nhiều vấn đề, it means:

• This causes many problems
• This creates many problems

It is a very common verb when talking about effects or consequences.

Examples:

• gây khó khăn = cause difficulties
• gây hại = cause harm
• gây áp lực = create pressure

Yes, the basic structure is very similar to English:

• Việc này = subject
• gây = verb
• nhiều vấn đề = object

So it follows a simple Subject + Verb + Object pattern:

• Việc này / gây / nhiều vấn đề
• This / causes / many problems

That makes this sentence fairly straightforward for English speakers.

Because nhiều means many, and in Vietnamese quantity words normally come before the noun.

So:

• nhiều vấn đề = many problems
• nhiều người = many people
• nhiều sách = many books

This is similar to English in this case.

Vietnamese nouns usually do not change form for singular or plural.

So vấn đề can mean:

• problem
• problems

The word nhiều tells you it is plural here:

• nhiều vấn đề = many problems

This is very common in Vietnamese. The number or quantity is shown by context or by words like:

• một = one
• hai = two
• nhiều = many
• vài = a few

Yes. Việc này gây ra nhiều vấn đề is also correct.

• gây = cause
• gây ra = cause, bring about

In many cases, gây and gây ra are both possible, and the meaning is nearly the same.
Adding ra can make the verb feel a little more complete or natural in some contexts, but gây by itself is already very common and correct.

So both work:

• Việc này gây nhiều vấn đề.
• Việc này gây ra nhiều vấn đề.

You can often use other words, but the tone and nuance change slightly.

• việc này = this matter, this affair, this task, this issue
• chuyện này = this matter, this story, this situation; often a bit more conversational
• điều này = this thing/this point/this fact; often more abstract or formal

Possible alternatives:

• Chuyện này gây nhiều vấn đề.
• Điều này gây nhiều vấn đề.

These are all possible, but they are not always interchangeable in every context.

A rough guide:

• use việc for a concrete matter, case, task, or situation
• use chuyện in everyday speech
• use điều for a more abstract point or statement

It is quite neutral.

Việc này gây nhiều vấn đề sounds natural in writing, speech, work discussions, news-like language, and general explanation.

It is not slangy, and it is not especially formal either.
If you want a more conversational feel, Chuyện này gây nhiều vấn đề may sound a bit more everyday.

Sometimes việc can mean job or work, but not always.

For example:

• tìm việc = look for a job
• công việc = work, job

However, in Việc này gây nhiều vấn đề, việc more likely means matter, issue, or situation, not job in the employment sense.

So translating it as This job causes many problems would only be right if the context is specifically about a task or piece of work.

Vietnamese does not use articles the way English does.

So vấn đề can mean:

• a problem
• the problem
• problem

The exact meaning depends on context.

In this sentence:

• nhiều vấn đề = many problems

English requires many problems, but Vietnamese does not need anything like the or a.

Yes. Depending on context, nhiều vấn đề can be translated in several natural ways:

• many problems
• a lot of problems
• many issues
• a lot of issues

The Vietnamese sentence itself does not force only one English wording.
The best translation depends on tone and context.

vấn đề usually means problem or issue. It often has a negative sense, but sometimes it can be more neutral, like matter or question under discussion.

Examples:

• Có vấn đề rồi. = There’s a problem.
• Tôi muốn bàn về vấn đề này. = I want to discuss this issue.

In Việc này gây nhiều vấn đề, it is clearly negative: this causes many problems.

If someone wants to emphasize the seriousness, they might stress:

• Việc này if they want to highlight this matter
• gây if they want to stress the idea of causing
• nhiều vấn đề if they want to stress many problems

For example:

• Việc này gây nhiều vấn đề. = This matter is what causes problems.
• Việc này gây nhiều vấn đề. = It really causes a lot of problems.

Vietnamese does not rely on stress in exactly the same way as English, but emphasis in speech still matters.

Yes. Việc này gây nhiều vấn đề is a complete and natural sentence.

It has:

• a subject: Việc này
• a verb: gây
• an object: nhiều vấn đề

It can stand alone without needing extra words.

If you want, you can expand it:

• Việc này gây nhiều vấn đề cho công ty. = This causes many problems for the company.
• Việc này đang gây nhiều vấn đề. = This is causing many problems.

But the original sentence is already complete.
