Novial is an international auxiliary language created by Otto Jespersen, a linguist from Denmark. Jespersen recognised a need for an international auxiliary language and thought there were many problems with Esperanto. With Novial he tried to cure those problems.
He first published details of Novial in 1928 in his book An International Language. In 1930 he published a Novial dictionary, Novial Lexike, which contained some changes to the language, and further modifcations were proposed during the 1930s. After Jespersen's death in 1943, Novial became dormant, but during the 1990s there was a revival of interest in the language.
Novial was designed to be easy to learn with vocabulary taken mainly from Germanic and Romance languages, and grammar based mainly on English.
