In English I guess it is clumsy, but is that the same part of speech? Or, I guess the word klutz is English now? I think of it as a Yiddish word. A person can be a klutz, but their behavior is klutzy I guess, like clumsy?
I think the German is Klotz.
I don’t think there is a Spanish equivalent? I speak Spanish pretty well, but I could be wrong. Torpe would be like clumsy, but you wouldn’t call someone a torpe.
Yiddish has some really great words, and it sounds funny too.
