The concept of Universal Grammar (UG) has emerged as Minimalist Program that studies the language at phrase-structure level. The principles of Universal Grammar are meant to be principally based on universally accepted criteria. The criteria, also known as “criteria of adequacy” consist of four principles: adequate description, explanation, definition and learnability, which govern the categorization of parameters at phrase-structure level to be applicable to all languages of the world. The present study aimed at analyzing the parameter setting of Urdu as a mother tongue in the language acquisition process of a child at a very early stage in terms of subjects, null subjects and head-positions parameters. It was found that wh-parameters were quite difficult for the children to acquire and there were certain differences and similarities in terms of the efficient setting of specific parameters.
