The corpus of concepts and methods we utilise in the practical study of literature is referred to as "literary theory." We don't mean the meaning of a piece of literature when we say literary theory; we mean the theories that indicate what literature might signify. Literary theory is an explanation of the fundamental ideas, or tools, that we use to try to understand literature. All literary interpretation has a theoretical foundation, yet it can be used to justify a wide range of critical activities. Literary theory examines the significance of race, class, and gender for literary research, both from the position of the author's biography and an analysis of their thematic content.
