The language of the Iyra species from the planet F'tral had both a spoken and a written component. The language's written form utilized symbols made up of dots and curves. The term F'tral in the Iyra's own speech signified "water." Consequently, F'tral became the designation for the water-covered planet that was the Iyra's homeworld.
The mother tongue of the Iyra receives an oblique reference within Galaxy Guide 4: Alien Races, a resource for the Star Wars: The Roleplaying Game system created by West End Games. This book, penned by Troy Denning and initially released in 1989, indicates that the word F'tral translates to "water" in the Iyra's language, although the specific name of their language is not provided. The 1995 sourcebook titled Galaxy Guide 12: Aliens — Enemies and Allies adopts the perspective of an Iyra sentientologist named Tem Eliss. The scientist's signature offers a visual representation of the Iyra's writing system.
