Cosmoglottics
Cosmoglottics is a science that investigates world languages ; more specifically about universal artificial languages, its study and construction.
Cosmoglottics derives its name from the first planned language of Volapük and Esperanto. Volapük means "world speech" and is reflected in the German term Kosmoglosse, where kosmo refers to "world" instead of "universe", giving rise to cosmoglottics.
Sergey N. Kuznetsov makes an opposition between cosmoglottics, the science about universal planned language, and interlinguistics, the science about international languages and communication, founded by Otto Jespersen in 1931.
