Explanation

The adjective impermanent is useful for talking about things that are fleeting or transitory; bubbles, the summer, a baby's cute lisp, and a wonderful dream are all impermanent. Many religions, especially Buddhism, emphasize the impermanent nature of everything in life, and the inevitability of change. The word at the root of impermanent is permanent, from the Latin permanere, "endure, continue, or stay to the end."
