The present essay discusses the aspects of the process of language acquisition in relation to the development of the self. Methodological issues are discussed; particularly the integration of maturational and environmental factors in the development of language. Theories of the development of transformational generative grammars point toward maturational aspects, but must be complemented by and integrated with the experience of evolving communication between child and caregivers. Progressive steps in the acquisition of language are discussed with specific reference to the influence of such developments on the concept of the self. Rudiments of a functional self are extant even from within the womb, and develop a conceptual and communicative capacity well before the onset of language. The functional and developmental gains acquired through the emergence of language are indicated in expanding and elaborating the scope and depth of preexistent capacities, and adding new and powerful dimensions to the experiential and expressive capacity of the self, especially in relation to self-awareness and a sense of identity.
