Amilessë, Quenya for mother-name, was the name given to an elf at near birth by his or her mother. It is part of the essë, or naming, of High Elves, along with the father-name and epessë (nickname or honorific). The amilessë is a private name to an elf and is used by family and close friends. The mother-name was often quite significant because elven mothers had insight into the characters and abilities of their children, and many also had the gift of prophetic foresight.
For example Fëanáro ("spirit of fire") was the amilessë of Fëanor.
Also called Essi Apacenyo (names of foresight).
