LOS ANGELES: Why learn French when you could learn Klingon? The language created more than 30 years ago for the “Star Trek” race of long-haired warriors has moved boldly into pop culture where few other alien tongues have gone before.

With a new book about the classic Klingon starship, Bird-of-Prey, and a Klingon spoof of the “Gangnam Style” music video racking up millions of views on YouTube, Klingons are showing a fun side that outstrips their Trekkies fan base.

With their high-ridged foreheads, starships that boast cloaking devices and strict code of honor, Klingons are rivaling Mr. Spock’s Vulcans in the language and popularity stakes. “Klingons are these big, mean tough warrior guys, but they are also funny, so it is fun to behave like a Klingon,” said Marc Okrand, who created the guttural language and compiled the first Klingon dictionary in 1985.

Despite a tiny vocabulary of just 2,000 to 3,000 words, Klingon is the most spoken fictional language in the world, according to Guinness World Records. And last month saw a Swedish couple tie the knot in a Klingon wedding ceremony at London’s “Star Trek” convention.

There is already a Klingon Language Institute, Klingon translations of Shakespeare’s “Hamlet” and the Book of Mormon, a Klingon version of the board game Monopoly, a Dutch opera sung in Klingon, an annual Klingon staging of “A Christmas Carol” in Chicago, and a guided tour of Australia’s famous Jenolan caves near Sydney, conducted entirely in Klingon.

The latest arrival is the book, “Klingon Bird-of-Prey Owners’ Workshop Manual,” packed with illustrations, graphics and information (with Klingon subtitles by Okrand) about the starship’s weaponry, technical specifications and life on board.

The book comes about six weeks after the release of music video “Klingon Style” — a comic parody of wildly popular Korean pop star Psy’s Internet hit “Gangnam Style” — that has been viewed more than 3.8 million times on YouTube.
