Etymology: The most surprising thing about "diamond" is that it is the same word as "adamant" split into two forms. Both come from Ancient Greek "adámās", meaning "unconquerable" or "untameable", built from a privative prefix and a root related to "damnáō", "to subdue". The Greek word was applied to the hardest substances known, and it passed through Latin "adamās" and Late Latin "diamās" before reaching Old French as "diamant". English took the Old French form in Middle English as "dyamaunt", and the modern spelling settled later. "Adamant", meaning unyielding, came in more directly from the same Greek root, so the two words are doublets. A second twist comes from printing. In the trade, "diamond" also names a small size of type, roughly between "pearl" and "nonpareil". This sense is a calque of Dutch "diamant", used by the Dutch printer Dirck Voskens, who first cut that size around 1700. The gemstone sense and the printing sense therefore share the same metaphor of hardness and precision, while the type size keeps the name through a Dutch intermediary.
