    On July 26, 1887, Ludwig Lazarus Zamenhof published Unua Libro, the first book in the invented “universal” language of Esperanto. Today, Esperanto is the most popular international auxiliary language (IAL) in the world. An IAL is a language spoken by people who do not share the same native language.
    Esperanto is based on roots common in many European languages, such as French, German, and Russian. Zamenhof invented Esperanto to encourage communication and peace between the ethnic groups in his hometown of Bialystock, now a part of Poland. “In Bialystok the inhabitants were divided into four distinct elements: Russians, Poles, Germans and Jews; each of these spoke their own language and looked on all the others as enemies,” Zamenhof wrote.
    Today, more than a million people speak Esperanto. It is one of the easiest languages to learn—it’s phonetic, which reduces spelling errors, and only has 16 rules of grammar. For instance, all singular nouns end in O—amiko is friend, amo is love, geografio is geography.
