What is the definition of wraith?

A wraith is a ghost, spirit, spectre, phantom, or shade, often of dark nature. The Word wraith is used to describe evil spirits in many different types of literature and media. An example might be the Ring Wraiths, or the Nazgûl, from The Lord of the Rings Trilogy. These are wraiths as they are manelovent and evil. I hope my definition of "wraith" was helpful and a fair equal to your other sources.
