Compound interest. Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously-accumulated interest.
Guanches (also: Guanchis or Guanchetos) refer to the aboriginal Berber inhabitants of the Canary Islands. It is believed that they migrated to the archipelago around 1000 BC or perhaps earlier.
Gauchos still are an integral part of the ranching areas of Argentina, Uruguay, and Brazil, as glimpses of gauchos and the countryside in Uruguay attest. Today, musical groups and sports teams call themselves gauchos, clothiers sell hats, and the gaucho is a prime attraction on tours and often photographed.
