Quai cốc nhỏ.

• quai = handle
• cốc = cup
• nhỏ = small

So quai cốc means cup handle, and nhỏ describes that noun phrase.

In very literal English order, it is something like handle cup small.

Because Vietnamese often does not use a copula like English is before adjectives.

So:

• Quai cốc nhỏ = The cup handle is small

This is normal Vietnamese grammar.
Using là here would usually sound wrong or unnatural:

• Quai cốc nhỏ = correct
• Quai cốc là nhỏ = usually not correct in this meaning

A good rule for learners is: when something has a quality such as small, big, beautiful, expensive, Vietnamese often just puts the adjective after the noun phrase.

Because in Vietnamese, adjectives usually come after the noun they describe.

For example:

• cốc nhỏ = small cup
• quai cốc nhỏ = small cup handle / the cup handle is small

This is the opposite of normal English word order, so it often feels unusual at first.

They form a noun-noun combination:

• quai = handle
• cốc = cup
• quai cốc = cup handle / handle of a cup

In Vietnamese, this kind of structure is very common. The first noun is the main thing, and the second noun helps specify what kind of thing it is.

So here, quai is the main noun, and cốc tells you it is the handle of a cup.

It can be understood either way, depending on context.

1. As a sentence:

   • Quai cốc nhỏ. = The cup handle is small.

2. As a noun phrase:

   • quai cốc nhỏ = a small cup handle or the small cup handle

Vietnamese often relies on context and intonation to show which meaning is intended. In a textbook, it may be presented as a sentence, but in real life the same word sequence could also function as a noun phrase.

No, not necessarily.

Vietnamese often leaves out classifiers when the meaning is already clear, especially in short example sentences.

So Quai cốc nhỏ is possible.

But you may also hear longer versions such as:

• Cái quai cốc nhỏ.
• Cái quai của cái cốc nhỏ.
• Quai của cái cốc này nhỏ.

Adding cái can make the noun phrase feel more concrete, but it is not always required.

In Quai cốc nhỏ, the most natural reading is that nhỏ describes the whole noun phrase quai cốc:

• [quai cốc] nhỏ = the cup handle is small / small cup handle

If you want to say the handle of the small cup, Vietnamese usually makes that clearer with của:

• quai của cái cốc nhỏ = the handle of the small cup

So yes, word grouping matters, and Vietnamese sometimes needs extra words if you want to remove ambiguity.

Both are possible, but they feel slightly different.

• quai cốc = shorter, more compact
• quai của cốc = more explicit, literally the handle of the cup

In natural speech, speakers often use the của version when the noun phrase is longer or when they want to be especially clear:

• Quai của cái cốc này nhỏ quá. = The handle of this cup is very small.

So quai cốc is not wrong, but quai của cốc can sound clearer in fuller sentences.

A simple learner-friendly guide:

• quai: roughly like kwy or kw-eye, with a level tone
• cốc: starts like co-, ends with a short clipped -k, with a rising sắc tone
• nhỏ: starts with nh like the ny in canyon, and has a hỏi tone

The tones are:

• quai = no tone mark, so a level tone
• cốc = acute accent ´, so sắc
• nhỏ = hook ?-like mark, so hỏi

For many learners, nhỏ is the hardest word here because of both the nh sound and the tone.

Yes, it is grammatical and understandable, but by itself it feels a little short and context-dependent.

In everyday speech, people often say something slightly fuller, such as:

• Quai của cái cốc này nhỏ. = The handle of this cup is small.
• Cái quai cốc này nhỏ. = This cup handle is small.

So Quai cốc nhỏ works well as a simple learning example, but real conversation often adds words like này, kia, cái, or của for clarity.
