How are we able to analyze symbols, as symbols? in other words, how does deconstruction work at a basic level

Originated by the philosopher Jacques Derrida, deconstruction is an approach to understanding the relationship between text and meaning. Derrida's approach consisted of conducting readings of texts with an ear to what runs counter to the intended meaning or structural unity of a particular text. The purpose of deconstruction is to show that the usage of language in a given text, and language as a whole, are irreducibly complex, unstable, or impossible. Throughout his readings, Derrida hoped to show deconstruction at work.
