Abstract
This paper attempts to show the real nature of Universal Grammar. Universal grammar is
separate part of human mind which makes language learning possible and generative. Universal
grammar is the symbolic and systematic rules inside our mind. These rules help us to classify, analyze,
differentiate, assimilate, understand and recognize human language. This paper determines the real
nature of philosophical grammar and discusses the modular and non-modular approach of it. I shall
examine the critical approaches of Wittgenstein and Chomsky and their comparison to investigate the
philosophical grammar.
