Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. High Quality Content by WIKIPEDIA articles Vendergood was a constructed language, the invention of the child prodigy William James Sidis. Sidis described the language in his second book, entitled Book of Vendergood, which he wrote at the age of eight. Apparently, the language was mostly based on Latin and Greek, but also drew on German and French as well as other Romance languages. It distinguished between eight different conjugations: indicative, potential, imperative absolute, subjunctive, imperative, infinitive, optative, and Sidis's own strongeable. Articles were grouped by a gender inflection that one observer described as more complex than a Japanese verb.
