Amortality was the condition of never having died and being unable to die, as an amortal entity was never "alive" to begin with. As amortality referred to entities that were never alive from the beginning, it was different from "immortality", which described a living being who was unable to die.
Known amortal creatures
Amortality was the principal common trait of non-beings. The best-known examples were Poltergeists, as they were described as "indestructible spirits of chaos", and were known to differ from ghosts (with whom they were often confused) in that they were never alive at one time. Boggarts, Dementors and possibly Banshees, all being creatures that were never truly alive to begin with and seemingly indestructible, are other types of amortal creatures.
