The intrduction to Unit 3 lays out the typology of language conflicts that forms the basis of chapters 11 through 15, which are named after the five categories of language conflict that comprise the typology. The categories of language conflicts we present are as follows: (i) indigenous minorities , (ii) geopolitical minorities, (iii) migrant minorities, (iv) dialect minorities, and (v) competition for linguistic dominance. The disparate natures of these categories are mostly apparent from their names, but it is still worth spelling out what they mean in the context of this book.
