resilience

In physics, resilience is the ability of an elastic material (such as rubber or animal tissue) to absorb energy (such as from a blow) and release that energy as it springs back to its original shape. The recovery that occurs in this phenomenon can be viewed as analogous to a person's ability to bounce back after a jarring setback. Author P. G. Wodehouse took note of this when he wrote: "There is in certain men … a quality of resilience, a sturdy refusal to acknowledge defeat, which aids them as effectively in affairs of the heart as in encounters of a sterner and more practical kind." The word resilience derives from the present participle of the Latin verb resilire, meaning "to jump back" or "to recoil." The base of resilire is salire, a verb meaning "to leap" that also pops up in the etymologies of such sprightly words as sally and somersault.
