What is the author's style in That Hideous Strength by C. S. Lewis?

The language in this novel is conversational and easy. It is easy to tell that C.S. Lewis is English because of some of his word choices. However, because many of the characters in this novel are part of an academic community, the vocabulary is lofty at times. While the language of the people within the world of academia is more formal, the narrator's language is more conversational. This structure makes reading long narrations enjoyable, but during lengthy portions of dialogue, reading is more tedious.
