fume: [14] Fume comes via Old French fum from Latin fūmus ‘smoke, steam’. This in turn went back to a prehistoric Indo-European *dhūmo-, which also produced Sanskrit dhūmás ‘smoke’ and Russian and Polish dym ‘smoke’. The word’s verbal use, ‘be very angry’, comes, like seethe, from the notion of being ‘hot or steaming with fury’. Derived words in English include fumigate [16] and perfume. => fumigate, perfume
