In their article "The language of text-messaging" (which appeared in 2009, in S.C. Herring, D. Stein & T. Virtanen (eds), Handbook of the Pragmatics of CMC. Berlin and New York: Mouton do Gruyter.), Crispin Thurlow and Michele Poff use the phrase,
Given this modest but growing body of research, it is surprising that public and policy-level discourse about text-messaging continues to fixate on its deleterious impact on literacy and standard language use -- especially of young people (see Thurlow 2006, 2007). No review of the literature on texting would, however, be complete without briefly considering this broader metadiscursive framework.
I googled this term "metadiscursive framework" and only got 8 hits, so I think it is relatively uncommon. The term "metadiscursive" is referring to "metadiscourse" which is discussion about a discussion (or maybe, about discussion). So I have a hand waving idea of what this means, but I will need to introduce it to the reader in plain language (using the magic of apposition).
Any ideas how I could define this term in plain language?
UPDATE
Here are some more examples of the term's usage:
From "Middle English medical recipes: a metadiscursive approach", here.
The first person singular pronoun is associated with authorial identity while its plural counterpart is connected to the concept of community. This is essential in the metadiscursive framework as it points at the idea of communication as always accounted for in terms of social contexts.
From "The Moral Resonance of Arab Media", here.
As I suggest, genre provides a way to discuss the organization of talk and poetry -- a "metadiscursive" framework -- as poets and signers build consensus over the kind of community that is best able to address the needs at hand.
