These lists are merely suggestions of what can be covered during the last 2 phases of a Language Acquisition course. Vocabulary is only one element of what is covered in a unit and the lists presented here would need to be a natural fit to a unit before being implemented.
Some of these topics are quite sophisticated and may not suit all age groups. As the phases in an MYP Language Acquisition course are not grade dependant, it would be better to use different topics if students are in the earlier MYP grades.
