Luật này rất rõ.

Word by word:

• luật = law
• này = this
• rất = very
• rõ = clear

So the sentence means This law is very clear.

In Vietnamese, demonstratives like này (this) usually come after the noun.

So:

• luật này = this law
• literally, it is closer to law this

This is normal Vietnamese word order. English says this law, but Vietnamese says law this.

Vietnamese often does not need a verb like is/are when describing something with an adjective.

So:

• Luật này rất rõ = This law is very clear

There is no separate word for is here. This is very common in Vietnamese.

Compare:

• Anh ấy cao = He is tall
• Trời lạnh = The weather is cold
• Luật này rất rõ = This law is very clear

Rất means very. It intensifies the adjective that follows it.

So:

• rõ = clear
• rất rõ = very clear

If you remove rất, the sentence becomes:

• Luật này rõ = This law is clear

That is still grammatical, just less emphatic.

Here rõ means clear, in the sense of easy to understand, not vague, or well defined.

With luật (law), rõ usually means the law is written or explained clearly.

It can also be used in other contexts, for example:

• nghe rõ = hear clearly
• nói rõ = say clearly / explain clearly
• không rõ = unclear / not known

Yes. Rõ ràng is very common and often sounds slightly more explicit or natural in some contexts.

So you could say:

• Luật này rất rõ ràng = This law is very clear

Both rõ and rõ ràng work.
Rõ ràng can feel a little fuller or more emphatic, while rõ is shorter and perfectly fine.

By itself, luật can mean law in a general sense or a law / legal rule, depending on context.

In this sentence, này makes it specific:

• luật này = this law

So here it refers to a particular law, not the legal system in general.

Vietnamese does not always use classifiers, especially with abstract or formal nouns.

Luật is an abstract/formal noun, so luật này is natural without a classifier.

Learners often expect something like a classifier because Vietnamese has many of them, but not every noun needs one.

Yes, that is a good way to understand this sentence.

Structure:

• luật = noun
• này = demonstrative
• rất = degree word
• rõ = adjective

So:

• Luật này rất rõ
• literally: law this very clear

That is a very typical Vietnamese pattern.

A rough pronunciation guide for English speakers is:

• Luật ≈ loo-uht
• này ≈ nai (with a rising tone)
• rất ≈ zut or ruht depending on accent
• rõ ≈ zaw or yaw with a dipping/rising tone

A few important tone notes:

• luật has a heavy, clipped tone
• này has a rising tone
• rất has a sharp, checked tone
• rõ has a dipping/rising tone

Exact pronunciation varies between northern and southern Vietnamese, especially for r and final consonants.

Yes, you can.

• rất rõ = very clear
• rất là rõ = also very clear

Rất là is common in speech and can sound a little more conversational or emphatic.
But rất rõ is already completely natural and slightly more concise.

It is grammatical and understandable, but in real usage many speakers might prefer:

• Luật này rất rõ ràng

That is because rõ ràng is a very common collocation for clear in the sense of rules, explanations, and statements.

Still, Luật này rất rõ is not wrong. It just sounds a bit shorter and more direct.

Yes. For example:

• Luật đó rất rõ = That law is very clear
• Luật kia rất rõ = That law over there / that other law is very clear

Very roughly:

• này = this
• đó = that
• kia = that over there / that one

So the noun stays first, and the demonstrative changes after it.

Here are some useful parallels:

• Quy định này rất rõ = This regulation is very clear
• Bài này rất khó = This lesson is very difficult
• Nhà này rất đẹp = This house is very beautiful
• Câu này rất hay = This sentence is very good / interesting

These all follow the same basic pattern:

• noun + này + rất + adjective
