The Klingon language is the language spoken by the fictional Klingons in the Star Trek universe. Within the fictional universe of Star Trek, klingon is derived from the original language spoken by the messianic figure Kahless the Unforgettable, who united the Klingon home-world of QoʼnoS under one empire more than 1500 years ago. Many dialects exist, but the standardized dialect of prestige is almost invariably that of the sitting emperor.
