Avalon (English)

Where does "Avalon" come from?

The name Avalon entered English from Latin Avallōnia, also seen in the phrase 'īnsula Avallōnis'[1]. This Latin form derives from Proto-Brythonic '*aβaln', meaning 'apple tree'[1], which descended from Proto-Celtic '*abalnā'[1][4] and ultimately from the Proto-Indo-European root '*h₂ébōl'[1]. Through these Celtic origins, the legendary Arthurian island is fundamentally remembered as an isle of apples.

Open questions

The Proto-Indo-European root for apple might not belong to the oldest layer of the proto-language, potentially representing a substrate term or regional borrowing rather than an original ancestral root. [2]
Scholars disagree on whether the underlying root connects to Semitic languages, Afro-Asiatic terms, or an Anatolian form reconstructed as *(s)h₂eml-. [2]
