romfartøyets
Romfartøyets is the possessive form of the Norwegian compound noun romfartøy, meaning spacecraft. The base romfartøy combines rom (space) and fartøy (vessel). In Bokmål and Nynorsk, the definite singular form is romfartøyet, and the possessive is formed by adding -s to that form, yielding romfartøyets to indicate ownership or attribution, as in romfartøyets hull (the spacecraft’s hull) or romfartøyets kontrollsystem (the spacecraft’s control system).
Morphology and usage notes: romfartøyet is the definite form used when referring to a specific spacecraft.
Context and nuance: The -s possessive in Norwegian is widely used for nouns borrowed from other languages
