Morphology

life + and + death

The phrase literally juxtaposes 'life' and 'death' to signal that both outcomes are at stake, so a learner who knows the meanings of 'life', 'and', and 'death' can infer it refers to a situation involving survival or serious risk. This compositional pattern is cross-linguistically common and follows straightforward semantics rather than an idiosyncratic idiom, making it transparent to a B1 learner.

Etymology

Life and death puts life and death next to each other to show the two most extreme outcomes: living or dying. Think of a battlefield or a very sick person where a choice can mean living or dying, so today the phrase means 'very serious' or 'high risk'.
