Elves are considered children until they declare themselves adults, some time after the hundredth birthday, and before this period they are called by child names.

On declaring adulthood, an elf selects an adult name, although those who knew him or her as a youngster might continue to use the child name. Each elf’s adult name is a unique creation, though it might reflect the names of respected individuals or other family members. Little distinction exists between male names and female names; the groupings here reflect only general tendencies. In addition, every elf bears a family name, typically a combination of other Elvish words. Some elves traveling among humans translate their family names into Common, but others retain the Elvish version.
