The Klingon language was originated by linguist Marc Okrand for the "Star Trek" franchise. He developed it for the films, starting with "Star Trek III: The Search for Spock" in 1984, creating a fully functional language with its own grammar and vocabulary. Okrand's work has since expanded, and Klingon has become a cultural phenomenon among "Star Trek" fans.
