nahuda wo tukemasu.

It is read:

なふだ を つけます
Romanization: nafuda o tsukemasu

A few pronunciation notes:

• 名札 = なふだ
• を is usually pronounced o in modern Japanese
• 付けます = つけます

So the whole sentence sounds like nafuda o tsukemasu.

名札 means a name tag or name badge.

It usually refers to the kind of label or badge that shows a person's name, often worn on clothing in places like:

• schools
• workplaces
• events
• stores

So it is not just the word name; it is specifically a physical tag or badge with a name on it.

を marks the direct object of the verb.

In this sentence, the thing being attached or put on is 名札, so it takes を:

• 名札を = the name tag as the object
• 付けます = attach / put on

So を shows that the action is being done to the name tag.

Also, even though it is written を, it is usually pronounced o.

Here, 付けます means to attach, to put on, or to wear something by attaching it.

With 名札, the nuance is not the same as putting on clothes. It is more like:

• pinning on a name tag
• attaching a badge
• wearing something that is fixed onto your clothing

So in this sentence, 付けます means to put on a name tag.

Yes. 付けます is the polite non-past form of the verb.

The dictionary form is:

付ける = つける

So:

• dictionary form: 付ける
• polite form: 付けます

This is the form often used in textbooks and polite everyday speech.

Japanese -ます forms do not work exactly like English present tense.

付けます can mean:

• put on / wear as a regular action
• will put on in the future
• sometimes a present/future statement depending on context

So 名札を付けます could mean things like:

• I wear a name tag
• I will put on a name tag
• Please put on a name tag if used in a certain situation, though that would more commonly be phrased differently

The exact time is understood from context.

The subject is not stated.

Japanese often leaves out the subject when it is obvious from context. So 名札を付けます could mean:

• I put on a name tag
• You put on a name tag
• He/She puts on a name tag
• We/They will put on name tags

Context tells you who the subject is.

This is very normal in Japanese.

In normal Japanese writing, spaces are usually not used.

So this sentence would normally be written as:

名札を付けます。

Textbooks often add spaces to help learners see the parts more clearly:

• 名札
• を
• 付けます

So the spaced version is just a learning aid.

Japanese uses different verbs depending on the kind of thing you wear or how you wear it.

For example:

• 着ます is used for clothes you put on your upper body
• はきます is used for things like shoes, socks, pants
• かぶります is used for hats
• 付けます is used for things you attach to your body or clothing

A 名札 is usually pinned, clipped, or attached, so 付けます is the natural verb.

This is why 名札を付けます sounds natural, while using a general clothing verb would sound wrong or unnatural.

The casual form is:

名札を付ける。

Comparison:

• polite: 名札を付けます。
• casual/plain: 名札を付ける。

The meaning stays basically the same, but 付けます sounds polite and neutral, while 付ける sounds more casual or plain.
