Is 'väggen' not 'the road' or 'the way'?
No, that's vägen. Important difference!
Any difference in pronunciation?
Long vowel vs short vowel. Changes meaning drastically in many Swedish words.
vägen long vowel http://sv.forvo.com/word/v%C3%A4gen/#sv
väggen short vowel http://sv.forvo.com/word/v%C3%A4ggen/#sv
Edit, PS, also the consonant is longer when it's doubled.
The graffiti girl
True artists are not limited to paper.
Why not "the girls draw on the wall"?
That should be accepted as Swedish doesn't distinguish between the present tense and the present continuous tense.
I thought I surely had heard it being said "Flickorna ritar på vägen." !!!
The sentence does make sense, doesn't it?
