hardening
This term describes a transition from a soft, pliable, or vulnerable state to one of rigidity and resistance. In material science, it suggests a chemical or physical shift that increases durability and strength, often associated with curing or cooling processes.
In a psychological or social context, the word carries a colder, more negative tone. It describes a person becoming desensitized to pain or suffering, creating an emotional shield that prevents empathy or vulnerability.
