estancieroEtymologyBorrowed from Spanish estanciero.nounThe boss or supervisor in charge of the workers on an estancia.“Until the 1920's, Argentina was one of the wealthiest nations in the world, thanks to the fertile farms and ranches that spread over the pampa — the grasslands that stretch in a huge arc from Buenos Aires. Back then, free-spending estancieros reveled for months at a stretch in London, Paris and New York, returning just in time for La Rural.”
