never-say-die

The term "never-say-die" originates from the literal English imperative phrase "never say die," used as an exhortation to maintain courage and persistence. It became a popular slogan in the 19th century, notably associated with the unwavering spirit of characters in Charles Dickens's 1837 novel "The Pickwick Papers." Its transition from a verbal phrase to a hyphenated compound adjective exemplifies the linguistic process of lexicalization, where a common collocation fossilizes into a single lexical unit describing an indomitable attitude. The logic is transparent: the literal command to refuse to utter the word "die" (i.e., to admit defeat) metaphorically defines a quality of relentless optimism and tenacity.

This is a fixed idiomatic phrase adopted as a compound adjective. It is not productively formed from separable modern morphemes for analysis. The components are the English words 'never', 'say', and 'die'.
