Notes on Meaning

• Primary Meaning: The core meaning is a state of being toughened, either physically (like calloused skin) or, more commonly, emotionally/psychologically (like a hardened heart or attitude), due to repeated exposure to difficult circumstances.
• Figurative vs. Literal: It is most frequently used in a figurative sense to describe emotional resilience or desensitization. The literal meaning of physical calluses is also correct but often conveyed simply by "chai."
• Connotation: The word often carries a neutral-to-negative connotation, implying a loss of sensitivity or innocence. It is less about positive resilience ("kiên cường") and more about becoming numb or indifferent.
