"We are people."
Translation:My jesteśmy ludźmi.
Why not "ludzie?" As far as I understand ludzie is the plural for people . So, even though it was nominative, it still should be ludzie such as " oni sa ludzie" correct? PD: in this lesson there isn't any grammar focus, so please be humble enough to correct me or give me an idea why is this grammatical issue occurring.
Sentences like "X is Y" (We are Y) either take Instrumental for Y, or may be constructed as "X to Y" with Y being in Nominative, but that doesn't work if X was a pronoun, both X and Y would need to be noun phrases.
So here, the only option is with X = Nominative and Y = Instrumental. My jesteśmy ludźmi, Wy jesteście ludźmi, Oni/one są ludźmi.
