Translation:The plumber and the electrician are sisters.
I was wondering. Is there a gender ending in job nouns? I would have thought this sentence to be something more like: "Rørleggerinnen og elektrikerinnen er søstre", since we have seen an actor/actress translated to "skuspiller/-inn. A bit like French would have: électricien/électricienne and German would have: schauspieler/schauspielerin
