cloche

(early 12th century) from the Vulgar Latin clocca attested in the 7th century, derived from the Gaulish clocca (bell) reconstructed from the Cornish clogh, the Irish Gaelic clog, the Welsh cloch, and the Breton kloc'h, and imported into France by Irish missionaries; it has supplanted the Christian Latin signum ('signal') or campana ('bell').
