The Klingon language (tlhIngan Hol in Klingon) is the constructe language spoken by Klingons in the fictional Star Trek universe. Deliberately designed by Marc Okrand to be "alien", it contains many peculiarities, such as Object Verb Subject (OVS) word order. The basic sound (along with a few words) was first devised by actor James Doohan ("Scotty") for Star Trek: The Motion Picture. That film marked the first time the language had been heard on screen; in all previous appearances, Klingons spoke in English. Klingon was subsequently developed by Okrand into a fully fledged language.
