Låneapparatet er klar i butikken.

It is a compound noun:

• låne- = related to borrowing / being on loan
• apparat = device, apparatus
• -et = the definite ending for a singular et-word

So låneapparatet means something like the loaner device or the device for borrowing, depending on context.

Because Danish usually puts the at the end of the noun instead of using a separate article.

• et apparat = a device
• apparatet = the device

In this sentence, låneapparatet already includes the.

Here klar means ready, prepared, or available.

So it does not mean clear in this sentence. A learner will often meet klar in phrases like:

• Jeg er klar = I’m ready
• Maden er klar = The food is ready

In this sentence, it means the loaner device is ready for use, pickup, or collection.

i butikken means in the shop/store.

Danish uses i for being inside a place or located there. English sometimes says in the store and sometimes at the store, but Danish commonly uses i here.

• i butikken = in the store / at the store
• i en butik = in a store

So i butikken is the natural way to say the device is there in the shop.

Because it refers to a specific shop, usually one that is already known from the situation.

• butik = shop/store
• butikken = the shop/store

If you wanted to mean in a shop, not a specific one, you would say i en butik.

This sentence uses the basic Danish main-clause order:

• Låneapparatet = subject
• er = verb
• klar = subject complement
• i butikken = adverbial phrase of place

So it looks very similar to English: The loaner device is ready in the store.

A useful Danish rule is that the finite verb normally comes in second position in main clauses. For example, if you move the location to the front, you get:

• I butikken er låneapparatet klar/klart.

The verb er still stays in second position.

This is a very good question.

Since apparat is normally an et-word in Danish, learners often expect the predicate adjective to agree with it:

• et apparat
• therefore standard agreement would normally be klart

So in careful standard Danish, many learners would expect:

• Låneapparatet er klart i butikken.

However, in real-life Danish you may sometimes see klar used in this kind of sentence, especially because klar is a very common everyday word in expressions meaning ready.

So for your own Danish, klart is the safer grammar-based form if låneapparatet is literally a neuter noun meaning the device.

This can confuse English speakers.

In everyday Danish, låne can be used from either perspective, depending on context:

• Kan jeg låne din pen? = Can I borrow your pen?
• Kan du låne mig din pen? = Can you lend me your pen?

If you want to make lend out extra clear, Danish often uses låne ud.

In a compound like låneapparat, the idea is usually something that is provided on loan or for temporary borrowing.

Not always, but very often.

apparat can mean:

• a physical device or machine
• in some contexts, a system, setup, or apparatus in a more abstract sense

In this sentence, it most likely refers to a physical device, because that is the most natural reading of låneapparatet in a store context.
