Questions & Answers about Driftskostnaden er høy.
Because -en is the usual definite singular ending for many masculine nouns in Norwegian. The base noun is driftskostnad (an operating cost / operating expense), and driftskostnaden means the operating cost.
So:
- driftskostnad = operating cost
- driftskostnaden = the operating cost
In this sentence, Norwegian uses the definite form directly on the noun instead of a separate word like English the.
The -s- is a linking element used in compounds. The word is built from:
- drift = operation, running
- kostnad = cost
Together, driftskostnad means operating cost. The s helps connect the parts smoothly. This is very common in Norwegian compound nouns.
You will see similar patterns in other words too, where an s appears between parts of a compound even though it is not a separate word by itself.
