Aprovechategui is a beautiful fusion of two ancient languages, the Spanish and the Basque language, specifically the word is used taken advantage of the Spanish and the suffix tegui of euskera. Its meaning comes to be something like ventajista or taking advantage of situations that makes their way of life. The suffix tegui in euskera is "quality of" but is written tegi without u there is no shape "gu" in Basque. Therefore his correct writing would be [i] aprovechategi [i]. Aprovechategui is a word that is used fairly in the Basque country.
