Noam Chomsky is a linguistic theorist who coined and defined formalism in the language. Formalism is the structured formal grammar. This way of using grammar to construct sentences and language is based on a mathematical approach. Using this study, Chomsky was able to provide rules that established the way a sentence and paragraph come together. It may seem unusual that formalism is about grammar and language but it is considered to be a part of mathematics. Chomsky introduced this theory in the 1950s. Prior to this, Chomsky studied and worked with grammar and syntax as well as psychology for many years before formalism.
