The name of which country can be translated as "made of silver"?

In English the name "Argentina" comes from the Spanish language, however the naming itself is not Spanish, but Italian. Argentina (masculine "argentino") means in Italian "(made) of silver, silver coloured", probably borrowed from the Old French adjective "argentine" "(made) of silver" > "silver coloured" already mentioned in the 12th century. The French word "argentine" is the feminine form and derives from argent "silver" with the suffix -in.

The Italian naming "Argentina" for the country implies Terra Argentina "land of silver" or Costa Argentina "coast of silver". In Italian, the adjective or the proper noun is often used in an autonomous way as a substantive and replaces it and it is said l'Argentina.

The name Argentina was probably first given by the Venetian and Genoese navigators, such as Giovanni Caboto. In Spanish and Portuguese, the words for "silver" are respectively plata and prata and "(made) of silver" is said plateado and prateado. Argentina was first associated with the silver mountains legend, widespread among the first European explorers of the La Plata Basin.
