In connection with research into the question whether there was a universal order to second language acquisition, a related issue emerged, namely, the so-called LI = L2 hypothesis. This refers to the idea that the processes of first and second language acquisition are the same, or are characterized by the same sequence of development. The latter is a consequence of the fact that learners employ a common set of strategies which are part of the human language faculty.
