Eurolengo is a constructed language invented by Leslie Jones in 1972. He intended that it would become a common European language, "intended as a practical tool for business and tourism." The vocabulary consists of words borrowed from English and Spanish and made to conform to a consistent phonetic and orthographic system. Critics find a Spanglish flavor to the language, and that "reading is only straightforward if the requisite languages (in this case English and Spanish) are already familiar."
