The characteristic of something that can spoil or decay over time, especially food items.
The perishability of fresh fruits means they must be consumed quickly.
Perishability is formed from "perish" (from Latin "perire", meaning to die or pass away) and the suffix "-ability" (meaning the quality of being able to). The word refers to the quality of being able to perish or the tendency to decay or be destroyed.
Think of the word 'perish' which means to die or decay, and remember that 'perishability' refers to the quality of being able to perish.
