Kameratredningen trenger to personer.

It is a compound noun in the definite singular form.

You can break it down like this:

• kamerat = comrade / companion / partner
• redning = rescue
• kameratredning = companion rescue / buddy rescue
• kameratredningen = the companion rescue / the buddy rescue

In Norwegian, the definite article is often attached to the end of the noun instead of being a separate word like the in English.

The ending -en marks the noun as definite singular for many masculine nouns.

Here, the base noun is kameratredning, and the definite form is:

• en kameratredning = a companion rescue
• kameratredningen = the companion rescue

Even though the compound ends with -redning, which is often a feminine noun in isolation, many feminine nouns in Bokmål can also take the masculine-style definite ending -en. In practice, this is very common.

Because Norwegian normally writes compound nouns as one word.

So:

• kameratredning is correct
• kamerat redning is not the normal way to write it

This is very different from English, where similar expressions are often written as two words. Norwegian strongly prefers compounds to be joined together.

Trenger is the present tense of the verb å trenge.

So:

• å trenge = to need
• trenger = need / needs

Norwegian verbs do not change according to person the way English verbs do. The same form is used with all subjects in the present tense:

• jeg trenger
• du trenger
• han trenger
• vi trenger

That makes Norwegian verb conjugation simpler than English in this respect.

Because Norwegian builds this sentence more directly than English.

In English, you might say something like The companion rescue needs two people. Norwegian simply uses:

• Kameratredningen = the subject
• trenger = needs
• to personer = two people

There is no extra helping verb like does because that only appears in certain English sentence types, especially questions and negatives.

Because after a number greater than one, the noun is usually plural.

So:

• én person = one person
• to personer = two people

The plural of person is personer in Norwegian.

This is similar to English, where two person is wrong and two people or two persons is used instead.

To is simply the Norwegian word for two.

A few basic numbers are:

• en/ett = one
• to = two
• tre = three

There is no extra ending here because numbers themselves do not change in this kind of sentence.

The word order is the standard Norwegian main-clause pattern:

subject + verb + object

So here:

• Kameratredningen = subject
• trenger = verb
• to personer = object

This is very similar to normal English word order: The companion rescue needs two people.

Sometimes, depending on context, but not always with exactly the same tone.

• to personer = two persons / two people
• to folk = two people

Personer is a bit more neutral and precise.
Folk is common in everyday speech, but it can sound slightly less formal.

In instructional, technical, or safety-related language, personer is often the better choice.

This sentence is Bokmål.

A few clues:

• trenger is Bokmål-compatible
• personer is also normal Bokmål usage

A Nynorsk version might look different, depending on style and word choice.

In speech, the sentence would usually be said with the main stress on the important content words:

Kameratredningen trenger to personer.

Often, to personer gets clear emphasis because it gives the key information.

Also, the compound kameratredningen is spoken as one unit, not as separate words.

It is understandable and correct, but it is somewhat specialized rather than everyday casual vocabulary.

It is the kind of word you might encounter in:

• rescue training
• avalanche safety
• outdoor instruction
• emergency procedures

Norwegian often forms very specific compound nouns like this, especially in technical or practical contexts.
