Is his name "Grouchy", because he is actually a grouch? Do the names of characters in The Smurf are made of puns?

Yes, I believe so. It seems as though the Smurf's names are meant to fit their personalities. For example, there's a Clumsy Smurf who is very clumsy, Brainy Smurf who is really smart, and Gutsy Smurf who is very brave and daring.
