Sommario/riassunto |
|
This monograph is about how the Scots language is discursively constructed, both from 'above' (through texts such as educational policies, debates in parliament and official websites) and from 'below' (in focus group discussions among Scottish people). It uses the interdisciplinary discourse-historical approach to critical discourse analysis to examine what discursive strategies are used in different texts, and also to investigate salient features of context. This allows a broader discussion of the role of this language in Scotland, and how different ways of constructing a language can percolate |
