Albion was once the earliest known name of what is now Great Britain and is sometimes still used as a poetic name for it. It’s related to Latin albus meaning “white”, in reference to the White Cliffs of Dover, though I’ve also seen it related to Common Celtic *albiyo “white; upper world” as opposed to the underworld. It’s also been linked to Proto-Indo-European *alb meaning “mountain”.
Origin: Latin, Celtic, Proto-Indo–European
