An archaic or variant spelling of 'grail,' most famously the Holy Grail, a legendary sacred cup sought by knights.
From Old French 'graal' or 'greal,' possibly derived from Late Latin 'gradalis' (a serving dish); the spelling changed through Middle English into modern 'grail.'
Medieval writers couldn't agree on how to spell this word—versions included graal, grail, grale, and greal—showing how spelling was fluid before dictionaries standardized everything.
