How did Argentina get its name?

Answer 1

It got its name from the Latin word Argentum: which means "SLIVER"

The Uruguay/Parana river estuary north of Buenos Aires became known to early navigators as the Rio de la Plata or 'silver river', because of legends of a 'Sierra de la Plata' or silver mountain range upstream. Later the country took its name from the Latin word "Argentum" (You can find this in the Periodic Table of Elements #47 Silver, its symbol is Ag, as most element symbols derive from Latin words.) Thus creating the word Argentina.

Answer 2

Argentina is derived from the Latin Tierra Argentina, meaning Land of Silver.

Argentina comes from Sanskrit word "Arjuntana" meaning the Land of Silver.
