Toki Pona (translated as ‘the language of good’) is a philosophical and artistic constructed language designed for its small vocabulary, simplicity, and ease of acquisition. It was created by Canadian translator and polyglot Sonja Lang with the stated purpose of simplifying 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 (referred to as lipu pu in Toki Pona).
