Definition of metallic

The word "metallic" originates from the Latin word "metallicus," which means "relating to metals." This Latin word is derived from the noun "metallum," which means "mine" or "quarry," and is thought to be related to the Proto-Indo-European root "met-" meaning "to extract" or "to dig." The word "metallic" has been in use in English since the 15th century, initially meaning "of or relating to metal" or "Having the properties or characteristics of metal." Over time, the meaning of the word has expanded to include not only the physical properties of metals, such as their conductivity and luster, but also their uses, such as in manufacturing and technology. Today, the word "metallic" is used to describe a wide range of things, from the physical properties of metals to their uses in art, fashion, and design.
