From Wiki:
Elf can be pluralised both as elves and elfs. Something associated with elves or the qualities of elves is described by the adjectives elven, elvish, elfin or elfish. A convention of modern fantasy usage is: the v in elven or elvish refers to human-sized elves (who correspond more closely to the mythology of the Viking Era), whereas the f in elfin or elfish refers to tiny-sized elfs (who correspond more closely to the folklore of the Renaissance and Romantic Eras). They are also called:
