"You are impossible!"

Translation: Du är omöjlig!

[Sven-Ska]

When do you write omöjlig or omöjligt? I thought this sentence was omöjligt as that word was at the end..?

[Berniebud]

The "T" at the end of an adjective, in this case "Omöjligt", means it can only be used with "Ett" nouns.

"Det är omöjligt" - "It's impossible".

When you're describing a person or an "En" word, then it becomes "Omöjlig".

It has nothing to do with the position it is in a sentence.

Thank you very much

Ahhh. Tack!

I checked "Du är omöjlig" and "Ni är omöjlig" But it was put wrong. Is there a difference between them?

[Arnauti]

du is used for singular and ni is used for plural. However, some people use ni as a ”polite pronoun”, so Ni är omöjlig should have been accepted (I've added it now).

The 'polite' usage of ni is a bit controversial: most people in Sweden don't do it, and some may be offended by it. But it seems to be quite normal in Finland. See this discussion, including the comments: https://www.duolingo.com/comment/5591933

Är can be are rite.

[Byx-]

Är = is, am, are
The swedes, they like their är's

[JamelSheperson]

What does that mean? I guess it's an expression but I don't get its meaning (in English neither)

[Rariera02]

(in English at least) it roughly means 'you are infuriating/extremely annoying' or 'I can't deal with you! (Because of aforementioned infuriation caused by a person.)
