The state of being weak or old, often related to the natural decline that comes with age, or the quality of being temporary and not lasting long.
As people age, they often face the caducity of their physical abilities.
Caducity is formed from "cadere" (meaning to fall) and the suffix "-ity" (meaning the state or condition of). The term refers to the state of being subject to falling or decay, often used in the context of mortality or the transitory nature of life.
Think of 'falling' ('cadere') to remember that 'caducity' refers to the state of decay or the transitory nature of life.
