Fairwaydriveren brukes på fairwayen.

Because -en is the definite singular ending for many Norwegian nouns of common gender.

So:

• en fairwaydriver = a fairway driver
• fairwaydriveren = the fairway driver

and

• en fairway = a fairway
• fairwayen = the fairway

Unlike English, Norwegian usually puts the at the end of the noun instead of as a separate word in front.

Brukes is the passive form of bruke.

• bruker = uses / is using
• brukes = is used / gets used

So:

• Fairwaydriveren bruker ... would mean The fairway driver uses ..., which does not make sense here.
• Fairwaydriveren brukes ... means The fairway driver is used ...

This -s passive is very common in Norwegian.

Because Norwegian often makes the passive with -s attached to the verb instead of using a separate helping verb.

So English:

• is used

often corresponds to Norwegian:

• brukes

Another possible Norwegian passive is:

• Fairwaydriveren blir brukt på fairwayen

That also means The fairway driver is used on the fairway, but brukes is shorter and very natural.

Norwegian often uses the definite singular to talk about a thing as a type or category.

So Fairwaydriveren brukes på fairwayen can mean something like:

• The fairway driver is used on the fairway
• in the sense of this kind of club is used there

This is normal in explanations, instructions, and general descriptions.

You could also hear:

• En fairwaydriver brukes på fairwayen

That means more like A fairway driver is used on the fairway. Both are possible, but the definite form is very natural when describing what something is for.

Norwegian uses på for many places and surfaces where English might use on or sometimes even in.

With golf areas, på is the natural choice:

• på fairwayen = on the fairway
• på greenen = on the green

Using i here would sound wrong or at least unnatural in standard usage.

Yes. In Norwegian, compound nouns are normally written as one word.

So:

• fairway + driver = fairwaydriver
• fairwaydriver + en = fairwaydriveren

This is very typical of Norwegian. English often writes similar expressions as two words, but Norwegian usually joins them into one compound.

Fairwaydriver is normally treated as a common gender noun, which is why it takes:

• en in the indefinite singular: en fairwaydriver
• -en in the definite singular: fairwaydriveren

Many borrowed words in Norwegian become common gender by default, especially everyday nouns like this.

The same applies here to fairway:

• en fairway
• fairwayen

Yes. That is also correct.

There are two common passive patterns here:

• brukes — the -s passive
• blir brukt — the bli-passive

So these are both natural:

• Fairwaydriveren brukes på fairwayen
• Fairwaydriveren blir brukt på fairwayen

Very roughly:

• brukes can sound a bit more neutral, general, or factual
• blir brukt can sound a bit more verbal or event-like

But in many cases, the difference is small.

The sentence follows normal Norwegian main-clause word order:

• Fairwaydriveren = subject
• brukes = verb
• på fairwayen = prepositional phrase

So the pattern is:

• Subject + verb + other information

This is the same basic order as in English here:

• The fairway driver is used on the fairway

The main difference is that Norwegian expresses the passive with brukes instead of is used.
