boilermaker

the word 'boilermaker' is a transparent compound formed within english from two pre-existing english words. the first element, 'boiler', originates from the verb 'boil', which has old english and germanic roots related to bubbling and heating liquids, combined with the agentive suffix '-er' to denote a vessel. the second element, 'maker', derives from the old english verb 'macian' (to make), also with the agentive suffix '-er'. the term first literally described a craftsman who fabricated steam boilers. its later, informal meaning as a mixed drink is an american 20th-century innovation, humorously applying the industrial term to a potent combination of beer and whiskey, perhaps evoking the strength or heating effect associated with its namesake trade.

Structure: boiler + maker boiler (english, from 'boil', a noun-forming suffix '-er' added to a verb, meaning a vessel for boiling); maker (english, from the verb 'make' with the agent noun suffix '-er', meaning one who makes or constructs).
