Hello everybody!

My sister and I had this discussion last night, and it turned out 
that we (having English as a second language) cannot really put a 
finger on the differences between or exact definitions of the 
terms "spell", "charm", "hex" and "jinx" as used in HP. 

Could anyone please explain this? Or, if it has been discussed 
before, point me to the explaining message(s)?

Thanks a lot, and have a nice week everyone. :-)
