Magic
From t2twiki
Magic is a contentious issue in T2T and in discussions of Middle-Earth in general. Some say that only Istari could do magic, yet a more careful reading of the text will reveal subtle "magic" use by nearly all races. Hobbits were the only ones said not to know magic. However, their ability to move without being seen was regarded by some as a form of magic. Elves also didn't regard their own powers as magic. So, we can safely assume that magic is a generic term, used or misused to describe a variety of natural and unnatural abilities. The available spells in T2T are an imperfect reflection of this murky situation.
