Linguistic Interdependence


     The Linguistic Interdependence Hypothesis is developed by Cummins (1978) and he postulates that certain first language (L1) knowledge can be positively transferred during the process of second language (L2) acquisition. The L1 linguistic knowledge and skills that a child possesses can be extremely instrumental to the development of corresponding abilities in the L2. Thus, this hypothesis proposes that development of competence in L2 is partially dependent on the type of competence already developed inL1 at the time when extensive exposure to L2 begins. Linguistic interdependence means that one language formation is dependent on another language competence.
