What does steel mean?
Steel is a hard, strong alloy made chiefly from iron and carbon, valued for its durability, tensile strength, and resistance to wear. It is used in construction, transport, tools, weapons, machinery, and many household objects. In figurative expressions, steel represents hardness, composure, and determination: a person may steel themselves for a difficult task or be described as having a steel resolve. The word can also function as an adjective, meaning made of steel, and as a verb, meaning to make someone or something mentally or physically tough. Although steel is metallic in appearance, it is not a pure element; its properties depend on its composition and processing. In everyday language, steel often carries connotations of strength and reliability, while phrases such as steel oneself suggest preparing to endure difficulty.

Where does steel come from?
The English word descends from Old English stēl, meaning steel, and ultimately from a Germanic root associated with a firm or unyielding quality. Its close relatives include Dutch staal, German Stahl, and Old Norse stál, all referring to steel or the metal from which cutting tools were made. The word entered English in an early Germanic form and developed into the modern noun, adjective, and verb.
