Resilience
Etymology
From Latin "resilire" (to leap back, rebound, recoil), from "re-" (back) plus "salire" (to jump) — the same root as "salient" and "somersault." The physical image is exact: resilience is a material’s tendency to spring back to shape after being bent. Psychology and ecology borrowed the word for systems that recover after a shock.
noun · /ri-ZIL-yuhns/
The capacity to recover from difficulty, adapt to hardship, and spring back to functioning.
What it names
Reach for it to name not the avoidance of adversity but the bounce-back after it — in a person, a community, or an ecosystem.
Example
The town’s resilience after the flood surprised even the officials who had written it off.
Related idea
Robustness is resisting damage in the first place — staying unchanged under stress; resilience is recovering after damage occurs. Antifragility goes one step beyond both: actually gaining from disorder rather than merely surviving it.
noun · /ri-ZIL-yuhns/
In physics, a material’s ability to absorb energy when deformed and spring back to its original shape.
What it names
a material’s capacity to rebound elastically
Example
Rubber’s resilience lets the ball bounce back to nearly its starting height.
Related idea
The same rebound as the psychological sense, measured in a material rather than a person.
