Literary theory provides principles for interpreting and analyzing literature. It focuses on analyzing the formal elements of a text, such as structure and language, rather than historical context. There are several benefits to studying different literary theories. It can affirm one's perspective, help understand other viewpoints, and provide a deeper understanding of a work by considering multiple interpretations. Formalism is a major literary theory that emerged in the early 20th century. It emphasizes close analysis of literary form and technique rather than historical context. Two influential forms of formalism were Russian Formalism and New Criticism. Russian Formalism studied poetic language and techniques like defamiliarization, while New Criticism advocated intensive analysis of the text itself.
