steel

This word carries a heavy sensory association with industrial strength, coldness, and rigidity. When used as a noun, it evokes images of skyscrapers, railway tracks, and heavy machinery, suggesting a material that is nearly impossible to bend or break. When applied to human emotion or behavior, it suggests a deliberate shutting down of vulnerability. To steel oneself is to create a psychological armor, mimicking the properties of the metal to withstand emotional impact or fear. It is often used in high-stakes or tragic contexts where bravery is a requirement rather than a natural feeling.
