toughness

This term describes a capacity for endurance that blends strength with flexibility. In a psychological sense, it refers to a resilient mindset that allows an individual to recover quickly from failure or persist through extreme stress without breaking. It is often associated with grit and emotional stability. In materials science, the word describes a specific physical property where a substance can withstand significant impact or stress. Unlike hardness, which resists scratching, this quality focuses on the ability to absorb energy and deform rather than shattering instantly.
