Otto Jespersen

Novial is an international auxiliary language (IAL) created by Danish linguist Otto Jespersen in 1928. It was designed to facilitate communication between speakers of different native languages. The name of the language is a blend of the Novial word novi (meaning 'new") and IAL.

Danish linguist (1860–1943)

Interlinguistics, also known as cosmoglottics, is the science of planned languages that has existed for more than a century. Formalised by Otto Jespersen in 1931 as the science of interlanguages, in more recent times, the field has been more focused with language planning, the collection of strategies to deliberately influence the structure and function of a living language. In this framework, interlanguages become a subset of planned languages, i.e. extreme cases of language planning.
