Able, ha? Skillful, capable - those are the words I would use to describe "ugyes."
Is the word tökéletes where the Hungarian phrase 'tök jó' comes from? Something is perfectly good? I've heard tök used with a variety of other adjectives as well, such as tök sötét = perfectly dark?
"Tok jo" is a slang. "Tok" means something like "very" but I wouldn't use it in an English course.
Able is képes, not ügyes.
