fuming (adj.)

c. 1400, "to fumigate" (transitive), from Old French fumer "to smoke, burn" (12c.), from Latin fumare "to smoke, steam," from fumus "smoke, steam, fume" (from PIE root *dheu- (1) "dust, vapor, smoke"). Intransitive meaning "throw off smoke, emit vapor" is from 1530s; the figurative sense "show anger, be irritated" is slightly earlier (1520s). Related: Fumed; fumes; fuming.
