Etymology
From Middle English morfounden, morefounden (“to take cold”), from Middle French morfondre (“to chill, to cool”), from Franco-Provençal mor, more (“snout”) + Middle French fondre (“to melt”), where the first part comes from Vulgar Latin *murrum (“muzzle, snout”), and the second from Latin fundere. Cognate with French morfondre. The noun is inherited from Middle English mareffownd, mareffownde, likely from the Middle English morfounden, morefounden (“to take cold”).
