Noun: rutabaga (American and Canadian), swede (British), a root vegetable that is a cross between a cabbage and a turnip.
Colloquial (and not often heard nowadays): head, brain, ”noodle.”
Lanttu comes from the Swedish planta (“seedling”). The word in Finnish has its origins in the fact that unlike a turnip, the a rutabaga needs to be grown from seedlings to reach maturity in Finland’s short summer.
The American English word rutabaga comes from the Swedish word rotabagge which means ”root bag.”
