Alien language in science fiction

A formal description of an alien language in science fiction may have been pioneered by Percy Greg's Martian language in his 1880 novel Across the Zodiac, 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.
