A gaucho () or gaúcho () is a skilled horseman, reputed to be brave and unruly. The figure of the gaucho is a folk symbol of Argentina, Uruguay, Rio Grande do Sul in Brazil, southern part of Bolivia and the south of Chilean Patagonia. Gauchos became greatly admired and renowned in legend, folklore, and literature and became an important part of their regional cultural tradition. Beginning late in the 19th century, after the heyday of the gauchos, they were celebrated by South American writers.
The gaucho in some respects resembled members of other nineteenth century rural, horse-based cultures such as the North American cowboy ( in Spanish), of Central Chile, the Peruvian or , the Venezuelan and Colombian , the Ecuadorian , the Hawaiian , the Mexican , and the Portuguese .
According to the , in its historical sense a gaucho was a "mestizo who, in the 18th and 19th centuries, inhabited Argentina, Uruguay, and Rio Grande do Sul in Brazil, and was a migratory horseman, and adept in cattle work". In Argentina and Uruguay today, gaucho can refer to any "country person, experienced in traditional livestock farming". Because historical gauchos were reputed to be brave, if unruly, the word is also applied metaphorically to mean "noble, brave and generous", but also "one who is skillful in subtle tricks, crafty". In Portuguese the word gaúcho means "an inhabitant of the plains of Rio Grande do Sul or the Pampas of Argentina of European and indigenous American descent who devotes himself to lassoing and raising cattle and horses"; gaúcho has also acquired a metonymic signification in Brazil, meaning anyone, even an urban dweller, who is a citizen of the State of Rio Grande do Sul.
Etymology
Many explanations have been proposed, but no-one really knows how the word "gaucho" originated. Already in 1933 an author counted 36 different theories; more recently, over fifty. They can proliferate because "there is no documentation of any sort that will fix its origin to any time, place or language".
Resemblance theories
Most seem to have been conjured up by finding a word that looks something like gaucho and guessing that it changed to its present form, perhaps without awareness that there are sound laws that describe how languages and words really evolve over time. The etymologist Joan Corominas said most of these theories were "not worthy of discussion". Of the following explanations, Rona said that only #5, #8 and #9 might be taken seriously.
The dialect frontier theory
A different approach is to consider that the word might have originated north of the Río de la Plata, where the indigenous languages were quite different and there is a Portuguese influence. Two facts that any theory could usefully account for are: The word actually exists in two forms: Port. gaúcho and Sp. gaucho, both long attested. Gauchos are first mentioned by name in the Spanish colonial records for present-day Uruguay, often in connection with smuggling to Brazil (see below, Origins). Thus Azara wrote (around 1784):
Hence the Uruguayan sociolinguist José Pedro Rona thought the origin of the word was to be sought "on the frontier zone between Spanish and Portuguese, which goes from northern Uruguay to the Argentine province of Corrientes and the Brazilian area between them".
Rona, himself born on a language frontier in pre-Holocaust Europe, was a pioneer of the concept of linguistic borders, and studied the dialects of northern Uruguay where Portuguese and Spanish intermingle. Rona thought that, of the two forms — gaúcho and gaucho — the former probably came first, because it was linguistically more natural for gaúcho to evolve by accent-shift to gáucho, than the other way round. Thus the problem came down to explaining the origin of gaúcho.
As to that, Rona thought that gaúcho originated in northern Uruguay, and came from garrucho, a derisive word possibly of Charrua origin, which meant something like "old indian" or "contemptible person", and is actually found in the historical record. However in the Portuguese-based dialects of northern Uruguay the phoneme /rr/ is not easily pronounced, and so is rendered as /h/ (sounding rather like English h). Thus garrucho would be rendered as gahucho, and indeed the French naturalist Auguste de Saint-Hilaire, travelling in Uruguay during the Artigas insurgency, wrote in his diary (16 October 1820): The native Spanish-speakers of these borderlands, however, could not process the phoneme /h/, and would render it as a null, thus gaúcho. In sum, according to this theory, gaúcho originated in the Uruguay-Brazil dialect borderlands, deriving from a derisive indigenous word garrucho, then in Spanish lands evolved by accent-shift to gaucho.
