chain-smoking

The term is a modern compound, originating in the mid-20th century to describe a specific, intensive habit. The first element, "chain," draws on its core meaning of a connected series of links, metaphorically applied to the sequential, uninterrupted lighting of one cigarette after another. The second element, "smoking," directly names the activity. Thus, the compound's logic is vividly literal: it depicts the act of smoking as a continuous, unbroken chain, emphasizing the compulsive and habitual nature of the behavior.

Structure: chain (series) + smoking (act of inhaling smoke) - chain: From Old French chaeine, from Latin catena (chain, fetter). In this compound, it functions as a noun used attributively to mean "in a series." - smoking: From the verb smoke, from Old English smoca (smoke), plus the suffix -ing, which forms a gerund (noun) or a present participle (adjective). It denotes the act or practice of inhaling and exhaling tobacco smoke.
