Derrida developed the concept of deconstruction as a form of textual analysis. It focuses on how language and texts have multiple meanings due to differences in interpretation over time and space. Derrida argued that searching for a single fixed meaning in a text is misguided, as the unstable nature of signs and language means meanings are deferred and undecidable. His work challenged structuralism and emphasized how language constructs reality rather than reflects it. Deconstruction remains influential in literary theory by examining silences and absences in texts.
