The Klingon Dictionary is a book by Marc Okrand describing the Klingon language. First published in 1985 and then again with an addendum in 1992, it includes pronunciation, grammar and vocabulary. Preowned condition. Cover and/or pages may have cosmetic damage as I have bought most of my books secondhand and have owned them for a long time. They've either been displayed on shelves or stored in bins. Smoke free home. star trek sci fi klingon dictionary reference guide cosplay science fiction
