"She is a wizard."
Translation:Hän on velho.
I noticed that. I think it is a false friend, a word in one language that is spelled the same as a word in another language that has a different meaning. In German, "Bach" means "brook." In Welsh, bach means "small."
HOWEVER, you can use false friends to remember what a word means.
"Velho" in your language means "old". When you see it in Finnish, you think of an old man with a pointed hat and a long beard, a wizard.
