Transpiranto is a parody language, a caricature of the international auxiliary language Esperanto. The name contains a play on the Swedish verb transpirera, to perspire. The parody language was developed from 1929 by contributors to the publication Grönköpings Veckoblad (a Swedish satirical monthly whose title includes the word 'weekly'), through a series of comical translations of well-known Scandinavian songs and poems, more than 200 in all.
