The first Klingon words were made by the actor James Doohan in 1979 for the . When they made the third movie in 1984, Gene Roddenberry wanted to have a real language for the Klingons.

When writing in Klingon, some letters are always in uppercase and some are lowercase. This never changes because the letters are spoken differently when they are written differently.
