Các sản phẩm còn mới.

Các is a plural marker. It tells you that sản phẩm means products rather than just product.

So:

• sản phẩm = product / products
• các sản phẩm = the products / products in general

In many cases, Vietnamese nouns do not have to show singular vs. plural as clearly as English does, but các makes the plural meaning explicit.

Vietnamese often does not use a verb like to be in sentences where an adjective describes something.

In English, you say:

• The products are new.

In Vietnamese, you can simply say:

• Các sản phẩm mới.

or, in your sentence:

• Các sản phẩm còn mới.

So mới works as the predicate adjective, and there is no need for a separate word meaning are here.

Here, còn means still.

So còn mới means:

• still new
• still in new condition

This often suggests that time has passed or the speaker is considering wear and tear, but the products have remained new or fairly new.

Compare:

• Các sản phẩm mới. = The products are new.
• Các sản phẩm còn mới. = The products are still new.

Mới just says something is new.

Còn mới adds the idea of still being new, often implying:

• they have been used only a little, or
• some time has passed, but they remain in good condition

So:

• mới = new
• còn mới = still new / still fairly new

In many contexts, còn mới can sound more natural when talking about the condition of objects.

It is written as two Vietnamese syllables: sản phẩm, but together they form one lexical item meaning product.

This is very common in Vietnamese. Many words are made up of two written syllables separated by a space.

So you should learn sản phẩm as a unit meaning:

• product
• item
• goods in some contexts

In this sentence, mới is not directly modifying the noun inside the noun phrase. It is the main predicate of the sentence.

Structure:

• Các sản phẩm = the products
• còn mới = are still new

So the adjective comes after the noun phrase because it is saying something about the products.

Compare:

• sản phẩm mới = new products
  Here mới is inside the noun phrase and modifies sản phẩm.

• Các sản phẩm còn mới = The products are still new.
  Here còn mới is the predicate.

No, not in normal reading.

In this sentence, còn combines naturally with mới to mean still new. Native speakers would understand:

• Các sản phẩm còn mới. = The products are still new.

The structure is not interpreted as products remain plus a separate adjective. Instead, còn functions like an aspect-like adverb meaning still.

No. Vietnamese often leaves number unstated when the context is clear.

For example, sản phẩm còn mới could still be understood as the products are still new or the product is still new, depending on context.

Adding các makes it clearly plural:

• Các sản phẩm còn mới. = The products are still new.

So các is useful when you want to make plurality explicit.

Not exactly.

Các mainly marks plurality, not definiteness. English the shows that the listener knows which things are being talked about. Vietnamese handles that differently and often relies on context.

Depending on context, các sản phẩm may be translated as:

• the products
• products
• these products in looser translation if context supports it

But các itself does not simply equal the.

A rough pronunciation guide is:

• Các ≈ gahk (with a sharp stopping sound at the end)
• sản phẩm ≈ sahn fuhm
• còn mới ≈ kawn muhy

A more important point for learners is the tones:

• Các: high rising/glottalized tone in Northern Vietnamese
• sản: hỏi tone
• phẩm: nặng tone
• còn: huyền tone
• mới: sắc tone

Exact pronunciation varies by region, especially North vs. South, but the meaning stays the same.

Yes, that is possible.

Both các and những can mark plural nouns, but they are not always identical in feel.

Very roughly:

• các can sound more like all the / the various
• những often sounds like some / several / the

In many everyday contexts, both are acceptable:

• Các sản phẩm còn mới.
• Những sản phẩm còn mới.

The exact nuance depends on context, but both can mean the products are still new.

Yes. It is short, grammatical, and natural.

It works especially well in contexts like:

• describing the condition of goods
• evaluating used items
• talking about stock or merchandise

For example, a seller might say it to mean that the products are still in new condition.
