"Väggarna är röda."

Translation: The walls are red.

[DehPuh]

So, väg means both road and wall? or are they "väg" and "vägg"?

[rhblake]

väg = road/way, vägg = wall

[CapdeBurro]

But it's said the same way?

[HelenCarlsson]

No, "väg" has a long "ä" and "vägg" has a short "ä".

Vägg: http://sv.forvo.com/search-sv/v%C3%A4gg/

I have immigrant friends who can't hear the difference :):

[NattKullav1]

For "vägg" I hear short "e".

[HelenCarlsson]

Det är bra! Short "e" = short "ä" :).

Falu rödfärg?

[Zmrzlina]

Most likely!

[buzzhagglund]

that's what I wrote and it was marked wrong

[devalanteriel]

There's a bug going around which causes that occasionally. It's very annoying, but we have no fix for it.
