Someone please help me with du vs. ni. I seem to remember some old Swedish friends telling me that "ni" can mean you all OR you in a formal sense of the word. Is that true? Does Swedish have formal vs. informal speech like that? Is it like the Spanish/French/ etc informal versus formal "you?" Or am I completely off and it is only singular vs. plural "you?" Please help! Tack!
You are right. Ni written with "big letter" means you in a formal sense of the word. This "Ni" is the word from 1940th. Right now it's almost disappear from the landuage but you still can hear it from the young people when they want to show older people extra respect. For example you can hear this word from the workes in McDonald's in Stockholm when you are ordering something ))))
Swedish nouns have different grammatical genders - common and neuter. Since common-gender nouns use en to mean "a/an", we call them en-words. And since neuter-gender nouns use ett to mean "a/an", we call them ett-words.
