The prose style of J. R. R. Tolkien's Middle-earth books, especially The Lord of the Rings, is remarkably varied. Commentators have noted that Tolkien selected linguistic registers to suit different peoples, such as simple and modern for Hobbits and more archaic for Dwarves, Elves, and Riders of Rohan. This allowed him to use the Hobbits to mediate between the modern reader and the heroic and archaic realm of fantasy. The Orcs, too, are depicted in different voices: the Orc-leader Grishnákh speaks in bullying tones, while the minor functionary Gorbag uses grumbling modern speech.
