Etymology
The compound adjective "life-and-death" is a modern English formation built from two of the language's most fundamental and ancient nouns, connected by the ubiquitous conjunction "and." Both "life" and "death" descend from Proto-Germanic roots (lībam and dauþuz respectively), which themselves trace back to Proto-Indo-European verbs concerning living and dying. The logic of the phrase is starkly literal, juxtaposing the two ultimate states of existence to create a powerful metaphor. It evolved from describing literal mortal peril to signify any situation of the utmost seriousness, where the stakes are metaphorically as high as survival itself. This transformation exemplifies how English uses concrete, elemental concepts to express abstract degrees of urgency and consequence.
