What is the difference between vit and vitt ?
Also, vitt can be the adverb form of vit and has another meaning ("wide", "widely") not related to colour as well.
Would it also be correct?: "Kvinnan har en vit klänning på sig"
I have seen sentences that were formed like this and I'm just confused when to use which variant.
Yes, either is perfectly fine. :)
Thank you! :)
