This document defines and explains literary criticism. It begins by exploring the origins and definitions of "critic" and "criticism" from Greek roots. A critic is defined as someone who expresses a reasoned opinion on a subject's value, truth, or technique. Criticism is the analysis and judgment of a literary work. The document then defines literary criticism as the study, discussion, evaluation, and interpretation of literature through various lenses or paradigms. It provides examples of different schools of literary criticism and explains them on a map with four variables: the work itself, the author, other texts, and the audience. The goal of literary criticism is to understand what is important about a text and its influences.
