Formalism is a literary theory that focuses on analyzing inherent features of a text such as grammar, syntax, and literary devices like metaphor, ignoring historical or cultural context. There are different schools of formalism including Russian formalism and New Criticism. Russian formalists aimed to analyze texts scientifically and defined literary techniques like defamiliarization, where common things are presented in unfamiliar ways to enhance perception. Defamiliarization makes objects strange through language, characterization, or illustration to transform ordinary prose into art. Examples include metaphors, Gulliver's Travels, and poems by Wordsworth, Keats, and Plath.
