kabekakedana wo tukeru.

It is read かべかけだなをつける.

A quick breakdown:

• 壁 = かべ
• 掛け = かけ
• 棚 = だな in this compound
• を is pronounced o
• 付ける = つける

In normal Japanese writing, it would usually appear without spaces: 壁掛け棚を付ける。

壁掛け棚 is a compound noun meaning a wall-mounted shelf or wall-hanging shelf.

It breaks down like this:

• 壁 = wall
• 掛け = hanging / mounted
• 棚 = shelf

So the idea is a shelf that is hung or mounted on a wall.

It functions as one noun.

Japanese often combines several elements into a single compound noun, especially for everyday objects. So 壁掛け棚 works like a single item name, similar to how English uses compounds like bookshelf or wall cabinet.

You could think of it as a product-name style noun.

This is because of rendaku, a common sound change in Japanese compounds.

On its own:

• 棚 = たな

But in some compounds, the first sound of the second part becomes voiced:

• た → だ

So:

• 壁掛け棚 = かべかけだな

This kind of change is very common, but not completely predictable in every word, so learners often just memorize the compound reading as a whole.

を marks the direct object of the verb.

So in this sentence, 壁掛け棚 is the thing being attached or installed.

Pattern:

• X を 付ける = attach/install X

So 壁掛け棚を付ける means that the wall-mounted shelf is the object being put up.

Here, 付ける means to attach, to put on, or to install/mount.

That is important because 付ける has many meanings in Japanese, depending on context. For example, it can also mean:

• to turn on
• to wear
• to add
• to write down
• to score/give points

But in 壁掛け棚を付ける, the natural meaning is to attach/install a wall shelf.

付ける is in the plain non-past form, also called the dictionary form.

That form can mean different things depending on context, such as:

• to attach/install
• attach/install
• will attach/install

So by itself, 壁掛け棚を付ける。 could be understood as:

• a dictionary-style expression
• a plan or intention
• a simple statement in plain style

Japanese relies heavily on context to decide the exact English tense.

Because the location is simply left out.

Japanese often omits information that is obvious from context. Since 壁掛け棚 already suggests something that goes on a wall, the sentence can just say 壁掛け棚を付ける.

If you wanted to say the location explicitly, you could say:

• 壁に壁掛け棚を付ける。 = attach a wall shelf to the wall

That may sound a little repetitive, but grammatically it is fine.

The subject is omitted.

Japanese very often leaves out the subject when it is understood from context. So this sentence does not explicitly say:

• I install
• you install
• someone installs

It just gives the action: attach/install a wall shelf.

Depending on context, the hidden subject could be:

• I
• you
• we
• they
• an unspecified person

No. Normally, Japanese is written without spaces between words.

So the standard written form is:

• 壁掛け棚を付ける。

Spaces are sometimes added:

• in beginner materials
• in textbooks
• for readability
• in design or labeling

But in ordinary Japanese writing, you should not expect spaces like this.

Often, yes.

• 付ける is a broad, everyday verb meaning attach/put on
• 取り付ける is more specific and often means install or mount something securely

For a shelf, especially one fixed to a wall, 取り付ける can sound more precise:

• 壁掛け棚を取り付ける。

So:

• 付ける = perfectly understandable and natural enough
• 取り付ける = a bit more specifically install/mount

Yes, you could.

• 壁掛け棚 is a compact compound noun
• 壁掛けの棚 is a more descriptive phrase meaning a wall-mounted shelf

The nuance is roughly:

• 壁掛け棚 = more like a set item name or product term
• 壁掛けの棚 = slightly more explanatory

Both are understandable, but 壁掛け棚 feels more like the standard noun for the object itself.
