Etymology Information

'furnace' originates from Latin, specifically the word 'fornax', where 'fornax' meant 'oven'.

Historical Evolution

'furnace' changed from Old French 'fornais' (or Old French forms from Vulgar Latin) into Middle English as 'furnace' and eventually became the modern English word 'furnace'.
