In the Land of Invented Languages: Esperanto rock stars, Klingon poets, Loglan lovers, and the mad dreamers who tried to build a perfect language - Arika Okrent

Just about everyone has heard of Esperanto, which was nothing less than one man’s attempt to bring about world peace by means of linguistic solidarity. And every Star Trek fan knows about Klingon, which was nothing more than a television show’s attempt to create a tough-sounding language befitting a warrior race with ridged foreheads. But few people have heard of Babm, Blissymbolics, and the nearly nine hundred other invented languages that represent the hard work, high hopes, and full-blown delusions of so many misguided souls over the centuries.
