The auxiliary language Interglossa (ISO 639-3: igs) was devised by the scientist Lancelot Hogben during World War II, as an attempt to put the international lexicon of science and technology, mainly of Greek and Latin origin, into a language with a purely isolating grammar. Interglossa was published in 1943 as just a draft of an auxiliary. Hogben applied semantic principles to provide a reduced vocabulary of just over 880 words which suffices for basic conversation among peoples of different nationality.
