Answer:
Genres are useful.
Step-by-step explanation:
Writers and readers both use genres because of the cognitive and social work they accomplish. For writers, using the patterns of a genre accepted by readers for accomplishing their purposes allows them to establish a working relationship with readers. Genre means a type of art, literature, or music characterized by a specific form, content, and style. For example, literature has four main genres: poetry, drama, fiction, and non-fiction. All of these genres have particular features and functions that distinguish them from one another. Genres form by conventions that change over time as cultures invent new genres and discontinue the use of old ones. Often, works fit into multiple genres by way of borrowing and recombining these conventions. In later periods genres proliferated and developed in response to changes in audiences and creators.
