Origin

*stak-, a Proto-Indo-European root meaning "to stay, to be firm," led to a root *stah- or *stag- ("to be firm, rigid") and then to Proto-Germanic *stahlą. In Proto-West Germanic, *stahl ("steel") was enlarged to *stahlī ("something made of steel"). This became Old English stīele and later Middle English stele.
