While linguistics is used by science fiction authors, it must be noted that not all uses are accurate to actual linguistics and its theories. Nevertheless, there still exists the lingering presence and use of linguistics (even if inaccurate) in such cases. As mentioned by Walter E. Meyers, the ability to make a story seem more unfamiliar and exotic, and an alien seem less of a costumed human who merely differs in physical appearance, is only possible through the use of language.[4] It is this ability that appears to draw the boundary between great works of science fiction and those lesser so.
