Etymology

The current spelling replaced the spelling key in the 1690s to emulate the spelling but (at least originally) not the pronunciation of the equivalent modern French quai. From Middle English kay, key, kaye, keye, from Old French kay, cail, from Gaulish kagyum, cagiíun (“enclosure”), from Proto-Celtic kagyom (“pen, enclosure”) (compare Welsh cae (“field”)), from Proto-Indo-European *kagʰyóm (“enclosure”). Doublet of hedge and hey (“choreographic figure”).
