Questions & Answers about Målelaboratoriet mottar sporfilmen.

Why is målelaboratoriet written as one word?

Because Norwegian usually writes compound nouns as a single word.
So målelaboratoriet is one compound noun, built from måle- + laboratoriet.

The same applies to sporfilmen: it is spor + filmen, written as one word.

This is much more common in Norwegian than in English, where similar ideas are often written as two words.

Why does målelaboratoriet end in -et?

The ending -et marks the definite singular of a neuter noun.

The base noun is et laboratorium. Its definite singular form is laboratoriet.
When that noun is the last part of a compound, it still takes the definite ending:

• et laboratorium → laboratoriet
• et målelaboratorium → målelaboratoriet

So målelaboratoriet means the measuring laboratory or the measurement laboratory.

Why does sporfilmen end in -en?

The ending -en marks the definite singular of a common-gender noun in Bokmål.

So:

• en sporfilm = an indefinite form
• sporfilmen = the definite form

That is why the sentence does not need a separate word for the before sporfilmen.
