Interlingua (/ɪntərˈlɪŋɡwə/; ISO 639 language codes ia, ina) is an international auxiliary language (IAL) developed between 1937 and 1951 by the American International Auxiliary Language Association (IALA). It ranks among the most widely used IALs and is the most widely used naturalistic IAL[2] – in other words, those IALs whose vocabulary, grammar and other characteristics are derived from natural languages, rather than being centrally planned. Interlingua literature maintains that (written) Interlingua is comprehensible to the hundreds of millions of people who speak Romance languages,[3] though it is actively spoken by only a few hundred.[1], From https://en.wikipedia.org/wiki/Interlingua
