"The ending is sad."

Translation: Slutet är sorgligt.

[gjwilkie]

Why not ledsen? Can only a person be ledsen?

[Arnauti]

Yes, exactly. ledsen is a feeling experienced by someone. Filmen var sorglig, jag blev ledsen 'The movie was sad, I got sad'. – It works the other way around too, if you say a person is sorglig, that will not be ambiguous as with sad, it will only mean that they are sad as in pitiable, not as in feeling sad.

[litibu]

in this case tråkigt works as well instead of sorgligt, isn't it?

[Zmrzlina]

No. Tråkig means boring, and would sort of trivialize the meaning.

[litibu]

Jasså. Sometimes it confuses me because some swedish friends use tråkigt when referring to something sad. Thanks by the way :)

[Zmrzlina]

Ah, yes. It's quite contextual, but its standard meaning is boring.

[HoroTanuki]

it's possibly coming from German traurig

[devalanteriel]

I don't think they're actually related - the Wiktionary page gives no indication of that.
