The grammar of the Klingon language was created by Marc Okrand for the Star Trek franchise. He first described it in his book The Klingon Dictionary. It is a nominative–accusative, primarily suffixing agglutinative language, and has an object–verb–subject word order. The Klingon language has a number of unusual grammatical features, as it was designed to sound and seem alien, but it has an extremely regular morphology.
