Subject: [norse_course] Simply searching for the word "maker"

 
Hello, folks!

I'm actually not interested in learning Old Norse right now, I'm just
trying to translate the word "maker" into Old Norse. I've found "to
make" as gøra "to make, build, compose, or write" and that's the form
I'd like. I just don't know how to form a gerund.

Could someone please help me out?

Thanks,
Amerie
