LEXIS: What in your view are the key morphological and typological challenges facing those who are learning English as a second or additional language? To what extent is the linguistic background (and especially the L1) of a learner a factor in this process in your view?
Guidance
You should illustrate your answer with extensive reference to specific examples of morphological and typological structures, as well as by giving examples of the forms that you regard as the most challenging aspects of these for a learner.
