Would this translate to "very sunny", or "actually sunny"?
We had the same discussion on a different thread, I think it was "Tha i gu math dorcha." I think I ended up still a bit confused, but I think the meaning is mainly the former.
I'm used to Go Mo'r, from another branch of Gaelic, which intensifies, from a' root of Big/Much.
Gu math looks like Greatly, which might have a positive value..
I am not sure.
