Idodalen

Idodalen is a constructed language (conlang) created by Swedish linguist and author Astrid Lindgren for use in her popular children's books about Pippi Longstocking. It is primarily spoken by Pippi herself, and occasionally understood or learned by her friends Tommy and Annika.

The language, as presented in the books, is not a fully developed, functional language with a complete grammar and extensive vocabulary. Instead, it consists of a collection of words and phrases that are often nonsensical or humorous, and sometimes resemble Swedish or other languages. The purpose of Idodalen is more to add to Pippi's eccentric and fantastical character rather than to serve as a practical means of communication.

Specific details about the grammatical structure or a comprehensive lexicon of Idodalen are largely absent. Its meaning is generally gleaned from context within the narratives. While individual words may be invented, the overall style and function of Idodalen are rooted in playful linguistic invention. It serves as a unique aspect of Pippi's persona, highlighting her independence, creativity, and rejection of conventional norms.
