Ga giường này sạch.

Ga giường means bed sheet. In everyday use, it often refers especially to the sheet that goes over the mattress.

A few related expressions:

• ga giường = bed sheet
• ga trải giường = bed sheet / sheet for covering the bed
• ga bọc nệm = fitted sheet

So in this sentence, ga giường này means this bedsheet.

In Vietnamese, words like này (this) usually come after the noun, not before it.

So:

• ga giường này = this bedsheet
• literally: bedsheet this

This is a very common Vietnamese pattern:

• nhà này = this house
• người này = this person
• cái bàn này = this table

So the position of này is completely normal.

Vietnamese often does not need a verb like is when an adjective describes something.

So:

• Ga giường này sạch.
• literally: This bedsheet clean.
• natural English: This bedsheet is clean.

This is a standard Vietnamese structure. Adjectives can act as the predicate by themselves.

No. You normally do not use là before an adjective like sạch.

Correct:

• Ga giường này sạch. = This bedsheet is clean.

Not natural:

• Ga giường này là sạch.

A simple rule:

• use là mainly when linking one noun to another noun
  
  • Anh ấy là bác sĩ. = He is a doctor.
• do not usually use là before adjectives
  
  • Anh ấy cao. = He is tall.
  • Căn phòng sạch. = The room is clean.

It is basically an adjective meaning clean, but in Vietnamese adjectives can behave a bit like verbs in sentences.

That is why sạch can stand directly after the subject:

• Ga giường này sạch.

So it is best to think:

• meaning: adjective = clean
• sentence behavior: can function directly as the predicate without is

This is very common in Vietnamese.

Vietnamese classifiers are common, but they are not always required.

You can say:

• Ga giường này sạch.
• Cái ga giường này sạch.

Both are possible. The version without cái is perfectly normal. Adding cái can sound a little more specific, concrete, or conversational, depending on context.

So learners should know:

• classifiers are important in Vietnamese
• but native speakers do not use them in every single noun phrase

The tones are:

• ga — level tone
• giường — falling tone
• này — falling tone
• sạch — heavy, short, low tone

A rough pronunciation guide for English speakers:

• ga ≈ gah
• giường is harder; in northern speech it begins somewhat like z or y depending on accent
• này ≈ like nye with a falling tone
• sạch ends abruptly because of the final ch and the heavy tone

If tone is your main concern, the most important contrast here is that sạch has a very strong, clipped tone.

Yes, if the context is clear.

• Ga giường này sạch. = This bedsheet is clean.
• Ga này sạch. = This sheet is clean.

If everyone already knows you are talking about a bedsheet, dropping giường is natural. But if you want to be more explicit, ga giường này is clearer.

Yes.

• Ga giường này sạch. = This bedsheet is clean.
• Ga giường này rất sạch. = This bedsheet is very clean.

You can also hear:

• Ga giường này sạch sẽ.

Sạch sẽ also means clean, but it can sound a bit fuller or more descriptive than plain sạch in some contexts.

Vietnamese nouns do not change form for singular vs. plural the way English nouns do.

So ga giường này is usually understood as this bedsheet in context, but Vietnamese itself does not mark singular in the noun form.

If you want to make plural very clear, you could say something like:

• những cái ga giường này = these bedsheets

So the sentence as written is most naturally understood as singular, but Vietnamese relies a lot on context.

Yes, the normal order here is:

noun phrase + adjective/predicate

So:

• Ga giường này = subject
• sạch = predicate adjective

Natural:

• Ga giường này sạch.

Not natural:

• Này ga giường sạch
• Sạch ga giường này

Vietnamese word order is different from English, but once you learn the pattern, this sentence is very straightforward.
