Màu xanh hợp với áo này.

It can mean either, depending on context.

In Vietnamese, xanh is a broad color word that can cover both blue and green. If speakers want to be more specific, they often say:

• xanh lá cây = green
• xanh dương or xanh da trời = blue

So Màu xanh hợp với áo này could mean Green goes well with this shirt or Blue goes well with this shirt, depending on the situation.

Màu means color, so màu xanh literally means the color blue/green.

Vietnamese often allows both forms:

• xanh = blue/green
• màu xanh = the blue/green color

Using màu can make it sound a bit more explicit, especially when talking about color as a thing in itself. In this sentence, màu xanh sounds like the color green/blue is what matches the shirt.

Hợp với means something like:

• to suit
• to go well with
• to match

So Màu xanh hợp với áo này means that the color blue/green looks good with this shirt.

A few similar examples:

• Màu đỏ hợp với bạn. = Red suits you.
• Giày này hợp với váy đó. = These shoes go well with that dress.

Vietnamese often puts the thing being discussed first, then says what it suits or matches.

So the structure is:

• Màu xanh = blue/green
• hợp với = goes well with
• áo này = this shirt

Literal order: Blue/green goes well with this shirt.

That is a very natural Vietnamese way to say it. English might express the same idea differently depending on emphasis, but the Vietnamese sentence structure is normal.

Này means this.

In Vietnamese, demonstratives like this and that usually come after the noun, not before it.

So:

• áo này = this shirt
• áo đó = that shirt

This is the normal pattern:

• noun + này = this + noun
• noun + đó/kia = that + noun

Sometimes yes, but Màu xanh hợp với áo này is clearer.

If you say Xanh hợp với áo này, it may sound a bit incomplete or less natural unless the context already makes it very clear that you are talking about a color. Adding màu helps show that xanh is being used as a noun-like color expression.

So for learners, màu xanh is the safer and clearer choice.

Vietnamese often does not need a verb like to be in sentences where English would use one.

English:

• Green is suitable for this shirt.

Vietnamese:

• Màu xanh hợp với áo này.

The verb hợp already carries the meaning of being suitable / matching, so no extra is is needed.

This is very common in Vietnamese grammar.

Sometimes in casual speech, people may shorten things, but hợp với is the standard and clearest form here.

So:

• hợp với áo này = suits this shirt / goes well with this shirt

The word với shows the relationship with the thing it matches. For learners, it is best to keep với.

Usually áo refers to an upper-body garment such as a shirt, blouse, or top. The exact English translation depends on context.

So áo này could be:

• this shirt
• this top
• this blouse

If the meaning shown to you is this shirt, that is a natural translation.

No, not by itself.

Màu xanh hợp với áo này means the color blue/green matches the shirt. It does not directly say that the shirt is blue/green.

If you want to say This shirt is blue/green, you would say:

• Áo này màu xanh.
• Áo này có màu xanh.

So the original sentence is about matching, not about the shirt’s own color.

You can replace màu xanh with a more specific color phrase:

• Màu xanh lá cây hợp với áo này. = Green goes well with this shirt.
• Màu xanh dương hợp với áo này. = Blue goes well with this shirt.
• Màu xanh da trời hợp với áo này. = Sky blue goes well with this shirt.

That is useful because xanh alone can be ambiguous.
