Bestill reservedelen til tross for at reparasjonskostnaden er høy.

Bestill is the imperative form of the verb å bestille (to order).

In Norwegian, the imperative is often just the verb stem:

• å bestille → Bestill!
• å kjøpe → Kjøp!
• å lese → Les!

So Bestill reservedelen ... means Order the spare part ...

Unlike English, Norwegian imperatives usually do not need a subject like you. The you is understood.

Because this is a command, and Norwegian normally leaves out the subject in the imperative.

So:

• Bestill reservedelen. = Order the spare part.

If you added du, it would usually sound unnatural in a normal command.

This is similar to English, where we say:

• Order the part.

not usually:

• You order the part.

Reservedelen is the definite singular form of reservedel.

• en reservedel = a spare part
• reservedelen = the spare part

In Norwegian, definiteness is often expressed by adding an ending to the noun:

• bil → bilen
• bok → boka / boken
• reservedel → reservedelen

So the sentence is talking about the spare part, not just a spare part.

Because Norwegian usually puts the definite article at the end of the noun instead of using a separate word before it.

Compare:

• English: the spare part
• Norwegian: reservedelen

That -en ending already means the.

A separate article like den is only used in certain situations, especially with adjectives:

• reservedelen = the spare part
• den nye reservedelen = the new spare part

So in this sentence, reservedelen by itself is completely normal.

Til tross for at means something like despite the fact that or even though.

It introduces a contrast:

• Bestill reservedelen til tross for at reparasjonskostnaden er høy.
• Order the spare part even though the repair cost is high.

It tells you that the action in the main clause should happen in spite of the situation in the second clause.

This is a fairly formal or neutral expression. In everyday speech, many people might also say:

• selv om reparasjonskostnaden er høy

That means almost the same thing.

Because til tross for and til tross for at are used in slightly different ways.

• til tross for + noun phrase
• til tross for at + clause

Here, what follows is a full clause:

• reparasjonskostnaden er høy

Since that part has a subject and a verb, Norwegian uses at.

Compare:

• til tross for den høye reparasjonskostnaden
  = despite the high repair cost
  (noun phrase)

• til tross for at reparasjonskostnaden er høy
  = despite the fact that the repair cost is high
  (full clause)

Because Norwegian very often forms compound nouns by writing them as one word.

Reparasjonskostnaden can be broken down like this:

• reparasjon = repair
• kostnad = cost
• reparasjonskostnad = repair cost
• reparasjonskostnaden = the repair cost

This is extremely common in Norwegian:

• bil + dør → bildør (car door)
• sommer + ferie → sommerferie (summer vacation)
• reparasjon + kostnad → reparasjonskostnad

English often writes these as separate words, but Norwegian usually combines them.

That -s- is a very common linking element in Norwegian compounds.

So:

• reparasjon
• reparasjonskostnad

The -s- does not usually change the meaning much; it mainly helps the compound sound natural.

You will see this in many words:

• arbeid → arbeidsdag
• regjering → regjeringsparti
• reparasjon → reparasjonskostnad

Unfortunately, this is not always fully predictable, so learners often just need to become familiar with common patterns.

Because the sentence refers to the repair cost as a specific, identifiable cost.

• reparasjonskostnad = repair cost / a repair cost in some contexts
• en reparasjonskostnad = a repair cost
• reparasjonskostnaden = the repair cost

Here, the speaker is talking about the cost of that particular repair, so the definite form makes sense.

This is similar to English using the when both speaker and listener know which cost is meant.

Because kostnad is a noun that takes the adjective form høy here.

In this sentence, høy is a predicate adjective after er:

• Kostnaden er høy. = The cost is high.

You often use the basic/common-gender adjective form in sentences like this when the noun is a singular common-gender noun.

Compare:

• En pris er høy.
• Kostnaden er høy.

You would see høyt with a neuter singular noun, for example:

• Nivået er høyt. = The level is high.

So høy matches the noun pattern here.

Yes, Norwegian commonly uses høy (high) with prices, costs, levels, temperatures, and similar things.

So these are all natural:

• høy pris = high price
• høy kostnad = high cost
• høy lønn = high salary
• høy temperatur = high temperature

So reparasjonskostnaden er høy is completely idiomatic Norwegian.

Yes. After at, Norwegian uses subordinate clause word order.

In this sentence:

• at reparasjonskostnaden er høy

the order is:

• subject: reparasjonskostnaden
• verb: er
• predicate adjective: høy

That is normal for a subordinate clause.

A useful thing to remember is that Norwegian subordinate clauses do not use the typical main-clause verb-second pattern. You can see this more clearly when an adverb is present:

• main clause: Kostnaden er ikke høy.
• subordinate clause: ... at kostnaden ikke er høy.

So while this sentence looks simple, it still follows subordinate-clause structure after at.

Yes. A very natural alternative is:

• Bestill reservedelen selv om reparasjonskostnaden er høy.

This means almost the same thing.

A rough difference in tone:

• selv om = very common, everyday even though
• til tross for at = slightly more formal or emphatic, like despite the fact that

Both are correct, but til tross for at can feel a little more written or formal.

It sounds mostly neutral to somewhat formal.

The main reason is the phrase til tross for at, which is a bit more formal than selv om.

So:

• Bestill reservedelen til tross for at reparasjonskostnaden er høy.
  = neutral/formal

• Bestill reservedelen selv om reparasjonskostnaden er høy.
  = slightly more everyday

Neither one is wrong; they just differ a little in style.
