Avalonia is a modern elaboration of Avalon, the legendary island of Arthurian lore. Avalon itself likely derives from Brythonic/Welsh afal “apple,” reflected in medieval Ynys Afallach, “island of apples.” Adding the classical place-forming suffix -onia yields the toponymic sense “land/realm of apples” or “the Avalon land,” giving Avalonia a mythic, pastoral meaning and a softly lyrical sound.
