You might want to move this to the English into Swedish forum for confermation. I'm Italian, but I listen to a lot of classical music, including Sibelius and Grieg songs. If I know my music correctly, this means I love you in Swedish!

This is Danish for "I love you". Simple as that. You have a nice friend. :-)

The Swedish first-person singular subject pronoun is "jag", so Swedish is eliminated. Also, I think the Swedish word for love is "älske", so is spelt differently.

"Jeg" is the first-person singular subject pronoun in both Danish and Norwegian. But whereas the second-person singular object pronoun in Norwegian is "deg", it's "dig" in Danish. Ergo, this is Danish, and not Swedish (or Norwegian, for that matter).

No virus, though. That ain't no German, but Danish.
