Magic
From Tolkien Gateway
Magic was a term used by the Hobbits to describe processes and abilities of objects which could not be explained out of their limited lore and knowledge.
- "For this is what your folk would call magic. I believe; though I do not understand clearly what they mean; and they seem also to use the same word of the deceits of the Enemy"
- ― The Fellowship of the Ring The Mirror of Galadriel
The effects which could be described magical, were of different natures.
