The average word length in a novel can vary widely. Generally, it might be around 4 to 5 letters per word. However, this can be affected by many factors such as the genre of the novel, the writing style of the author, and the era in which it was written. For example, in a historical novel set in a more archaic time, there might be more complex and longer words used compared to a modern, fast - paced thriller.
On average, the word length in a novel is about 4.5 letters. This is just a rough estimate. Novels written for a younger audience might have shorter words on average to make it easier for them to read. In contrast, literary novels aimed at a more sophisticated readership could potentially have a higher average word length as they might use more elaborate vocabulary.
