As a neglected genre in the academia, science fiction, silently but diligently, explored the frontier of intellectual horizon through ideas projected into the future in forms of stories woven around outer worlds in distant galaxies. In such endeavours, it relied heavily on world-building, whose foundation stones are alien races, cultures, and languages. In his novel, Dune (1965), American author Frank Herbert depicts the Other in the form ‘Fremen’; the desert-dwelling tribal natives of the planet Arrakis, for his English-speaking audience, and to achieve such an alien effect, he utilizes the vocabulary of Middle-Eastern languages in his portraying of the alien folk of Fremen. This study analyses underlying reasons behind Herbert’s choice of ‘alien vocabulary’ and his utilization of those words for the fictional nation-building in his novel, as well the translation of those words into the Turkish language in the Turkish edition of the novel; it being a language with a shared past with both of the languages aforementioned.
