smoker

The word 'smoker' is a transparent agent noun formation in English. Its core, 'smoke', originates from the Old English verb 'smocian', meaning "to emit smoke," which itself is derived from the Proto-Germanic root 'smuk-', related to the process of smoking or steaming. The addition of the agent suffix '-er', from Old English '-ere', follows a highly productive Germanic pattern for creating nouns that denote a person habitually performing an action. Thus, the literal "one who smokes" evolved from its original, more general sense of "one who emits smoke" to its dominant modern meaning specifying a person who consumes tobacco, and later extended to devices used for smoking food.
