Wizard, Witch and Warlock

[dradamsapple]

Um, ok.
I am really excited for all of you that are dressing up for the 
premiere! (I'm jealous, actually; considering how I can pull it off 
cheaply considering I just spent about $90 bucks for Halloween 
costumes and various gadgetry for my kids), but an interesting point 
of discussion happened in the car on the way to get the Halloween 
stuff:  
What is the difference between a Witch, a Wizard and a Warlock?
We initially thought that a Witch was just a female Wizard, but in re-
reading CoS (we've been studying up for the show!), Mr. Weasly comes 
back into the house just after Harry arrives at the Burrow and says 
something about an "old Warlock" in his office. (sorry, I'm in the 
middle of slice and bake cookies and don't have time to fetch the 
hard copy of CoS to quote it exactly).
Anybody have any insight to this important question? :-}
Thanks in advance and *please*, I want to see pictures of all of you 
dressed up in those wonderful costumes!!!
