Half-elf

Half-elves (also called Cha'Tel'Quessir in elven) were humanoids born through the union of an elf and a human. Whether a half-elf was raised by their human parent or their elven parent, they often felt isolated and alone. Because they took around twenty years to reach adulthood, they matured quickly when raised by elves (who think they look like humans), making them feel like an outsider in either place.
Most half-elves were descended from moon elves. Pairings of elves and other races also existed, though they were rare.
