Chú thích có niên đại của hiện vật.

Here, chú thích is a noun, meaning caption, annotation, or explanatory note. In a museum or display context, it usually refers to the text next to an object that gives information about it.

In this sentence, it does not mean the verb to annotate.

In this sentence, có means has or contains.

So:

• Chú thích có... = The caption has...
• In natural English, that may come out as The caption includes... or The caption gives...

Vietnamese uses có very often for possession or for saying that something includes something else.

Niên đại means the date, period, or historical age of something, especially in formal, historical, archaeological, or museum contexts.

It is not the usual everyday word for a person’s age. For that, Vietnamese normally uses tuổi.

So niên đại is more like:

• dating
• historical period
• era/date of origin

của is a very common word used to show possession or an of relationship.

So:

• niên đại của hiện vật = the artifact’s date/period
• literally: date/period of the artifact

This pattern is very common in Vietnamese:

• noun + của + noun

Examples:

• màu của xe = the color of the car
• tên của sách = the name of the book

Because Vietnamese usually puts the main noun first, and then adds của + noun after it.

So:

• niên đại của hiện vật = the artifact’s date

If you changed the order, you would change the meaning or structure. For example:

• Hiện vật có niên đại... would mean The artifact has a date/is dated...

That is a different sentence structure.

Hiện vật means artifact, object, or exhibit item, especially a physical object in a museum, archaeological site, or collection.

It is more formal and specific than a general word like đồ vật (thing/object).

So in this sentence, hiện vật suggests something like a museum piece or historical object.

Yes, it can be understood as a complete sentence.

The structure is:

• Chú thích = subject
• có = has/contains
• niên đại của hiện vật = object

So the basic pattern is:

• Subject + có + object

A very literal reading is:

• The caption has the artifact’s date/period.

It is understandable, but many native speakers might feel it sounds a little compressed or formal.

A more natural version could be:

• Chú thích có ghi niên đại của hiện vật.
• Chú thích ghi niên đại của hiện vật.

Adding ghi makes it clearer that the caption states, gives, or records the artifact’s date.

So the original sentence is possible, but a slightly fuller version may sound more natural in everyday usage.

Vietnamese does not have articles like English the and a/an.

So:

• chú thích can mean the caption or a caption
• hiện vật can mean the artifact or an artifact

The exact meaning depends on context. Vietnamese usually leaves this unstated unless it needs to be made specific in some other way.

Yes. Chú thích can be either a noun or a verb.

• As a noun: caption, annotation, note
• As a verb: to annotate, to add explanatory notes

In this sentence, it is a noun, because it is the thing that has/contains the information.
