🎤Pronunciation
🌳Etymology
Origin
Life derives from Old English 'līf', meaning the condition of living or animate existence. Expectancy originates from Latin 'expectare' (to await, look for), combining ex- (out) and spectare (to look), which evolved into the suffix '-ancy' denoting a state or quality. The compound 'life expectancy' emerged in the 19th century as a statistical measure of anticipated lifespan.
Breakdown
Life (Old English 'līf', animate existence) + expectancy (Latin 'expectare', to await; ex- out + spectare to look + -ancy denoting state). Together: the anticipated duration of remaining life.
