A formal description of an alien language in science fiction may have been pioneered by Percy Greg's Martian language (he called it "Martial") in his 1880 novel Across the Zodiac , [1] although already the 17th century book The Man in the Moone describes the language of the Lunars, consisting "not so much of words and letters as tunes and strange sounds", which is in turn predated by other invented languages in fictional societies, e.g., in Thomas More's Utopia .
As the science fiction genre developed, so did the use of the literary trope of alien languages.
Jonathan Vos Post analyzed various issues related to understanding alien languages. [2]
While space operas bypass the issue by either making aliens speak English perfectly, or resorting to an "universal translator", in most hard science fiction humans usually have difficulties in talking to aliens, which may lead to misunderstanding of various level of graveness, even leading to a war. [3]
Some science-fiction works operate on the premise that alien languages can be easily learned if one has a competent understanding of the nature of languages in general. For example, the protagonist of C. S. Lewis's novel Out of the Silent Planet is able to use his training in historical linguistics to decipher the language spoken on Mars.
Others work on the premise that languages with similarities can be partially understood by different species or could not be understood at all.
A number of long-running franchises have taken the concept of an alien language beyond that of a scripting device and have developed languages of their own.
The existence of alien languages and the ease or difficulty of translation is used as a plot device or script element in a number of franchises, sometimes seriously, and sometimes for comedic value.
In some cases, authors avoid linguistic questions by introducing devices into their stories that seamlessly translate between languages, to the point that the concept of different languages can largely be excluded from the narrative. Notable examples include:
In some cases, the question of language is dealt with through the introduction of a universal language via which most, if not all, of the franchise's species are able to communicate. In the Star Wars universe, for example, this language is known as Basic and is spoken by the majority of the characters, with a few notable exceptions. Other alien species take advantage of their unique physiology for communication purposes, an example being the Ithorians, who use their twin mouths, located on either side of their neck, to speak in stereo.
In some franchises this universal language is an intermediary language; one that different species can easily translate to and from their own languages, thus allowing simple communication between races. Examples of this approach include Interlac from the Legion of Super-Heroes, Babylon 5, and the Uplift Universe, where numerous sapient species use at least twelve "Galactic" languages (each version is used in communication between species that can articulate it, and that find it useful in expressing their concepts).
Not all of these universal/intermediate languages take the form of spoken/written languages as is recognized in the human world. In the film and book Close Encounters of the Third Kind scientists use Solresol, a language based on musical tones, while in the film and book Contact, aliens send the instructions to build a machine to reach them using mathematics, which the main character calls "the only universal language". Similarly, in Stargate SG-1 , the protagonists encounter a galactic meeting place where different races communicate with one another using a language based on atomic structures which is "written" in three dimensions rather than two.
Some science fiction stories imagine communication through telepathy.
