Frank Herbert's novel Dune, and his Dune series in general, incorporates a number of different themes related to language or linguistics, both in the techniques Herbert used in the actual writing itself, and more obviously, in the plot and characters. This is consistent with a broader theme of these novels, specifically, the nearly limitless power inherent in the human mind and body, and the power of training and discipline to enhance both physical and mental performance. Accordingly, heightened language skill and linguistic power are among the traits explored by Herbert in his works.
