resilience

In a psychological context, this word conveys an active, dynamic strength rather than a passive endurance. It is the "bounce back" factor—the ability to be bent or compressed by trauma, stress, or failure without permanently breaking. It carries a strongly positive connotation of growth and survival. While "toughness" implies a hard exterior that resists damage, resilience suggests a flexible interior that absorbs shock and returns to a state of equilibrium. In material science, the term is more literal, describing the physical property of elasticity. It refers to the energy stored in a material that allows it to return to its original form after being deformed.
