The world of books can be categorized into different genres. According to the Oxford Advanced Learner’s dictionary, the word genre is defined as “a particular type or style of literature, art, film, or music that you can recognize because of its special features.” 

A book genre is defined by particular features or functions that make it different from the rest. For instance, the features that make the genre of fantasy are entirely different from the features of historical fiction. The features or functions define that particular genre. It is important to identify which genre a book belongs to in order to understand the message it conveys.

Why is Book Genres Important?

A book genre becomes significant for both readers and writers. When you enter a bookstore, at first you browse through the genres, and then the books placed under it. The genre decides which place the book stays in a store. A reader more often picks up a title if they prefer that genre. 

As far as writing a book is concerned, it is crucial to know which genre your book belongs to. The genre decides the style, themes, message, and the length of your book. Even before you begin writing, choosing a genre becomes significant in a lot of ways.
