The Klingon Language Institute (KLI) is an organization dedicated to the study and promotion of the Klingon language, a constructed language from the Star Trek franchise. Founded in 1992 by Marc Okrand, the linguist who developed the language, the KLI provides resources for learners, including courses, dictionaries, and literature. The institute also fosters a community of Klingon enthusiasts through events, publications, and online forums. It encourages the use of the language in various contexts, from casual conversation to formal writing, helping to keep the Klingon culture alive among fans and linguists alike.
