drukčije

1. differently; in a different way
   Danas izgledaš nekako drukčije. — You look somehow different today.
   Ja o tome mislim drukčije od tebe. — I think differently about it than you do.
   Drukčije se ne može, moramo da čekamo. — There's no other way, we have to wait.

In comparisons it takes "od" + genitive: drukčije od tebe; the variant "drugačije" is equally common.
