The Klingons were created by screenwriter Gene L. Coon, and first appeared in the Star Trek episode "Errand of Mercy" (1967). They were named after Lieutenant Wilbur Clingan, who served with Star Trek creator Gene Roddenberry in the Los Angeles Police Department.
Klingon is a constructed language meant for a television series called Star Trek. And if you have seen the tv series it could be fun to learn it. Only two dozen people on Earth speak it fluently, and there are 3000 thousand words. So this language did not developed naturally. Only a few people can speak the Klingon language well enough to talk in it or to terrify someone by using it with a perfect vocabulary. It's powerful, if you speak it!
