Spanish is the official language. Uruguayan Spanish, like Argentine Spanish, has been somewhat modified by the Italians who migrated in large numbers to both countries. In general, the language of Uruguay is softer than that of Castile and some words are different from those commonly used in Spain. The gauchos have influenced the language, particularly in words dealing with their way of life. Brazilero, a Portuguese-Spanish mix, is spoken on the Brazilian frontier.
