Wikipedia

From Middle English flewme, fleume, fleme, from Old French fleume, Middle French flemme (French flegme), and their source, Latin phlegma, from Ancient Greek φλέγμα (phlégma, “flame; inflammation; clammy humor in the body”), from φλέγειν (phlégein, “to burn”). Compare phlox, flagrant, flame, bleak (adjective), fulminate. Spelling later altered to resemble the word's Latin and Greek roots.^[1][2]
