Toki Pona
Toki Pona is a philosophical artistic constructed language designed for its small vocabulary, simplicity, and ease of acquisition. It was created by Canadian linguist Sonja Lang to simplify her thoughts and communication. The first drafts were published online in 2001, while the complete form was published in the 2014 book Toki Pona: The Language of Good. Lang also released a supplementary dictionary, the Toki Pona Dictionary, in July 2021, describing the language as used by its community of speakers. In January of 2024, a third book was released, a Toki Pona adaptation of The Wonderful Wizard of Oz, written in sitelen pona. These three books are named pu, ku, and su respectively in Toki Pona.
