Morphology
life + expectancy
The meaning 'average number of years someone is expected to live' is directly derivable from combining 'life' (the period of living) with 'expectancy' (an anticipated duration), so a learner who knows both constituents can infer the MWE's sense. This is a compositional, cross-linguistically common concept and follows standard noun + noun semantics, making it readily understandable to B1 learners.
Etymology
Life expectancy comes from joining life (how long someone lives) and expectancy (a number people 'expect' from records). That's why life expectancy means the average number of years someone can 'expect' to live.
