It is viewed both as an activity, a real-time interactional tool, and a knowledge store consisting of a set of conventional linguistic units plus their combinatorial potential.
More detailed research has been carried out already on Akie, a traditional hunter-gatherer language of the Nilotic family spoken in north-central Tanzania.
As the work on the discourse in bilingual situations has shown, theticals play an important role both in code-switching and borrowing.
[15] Finally, a considerable part of the research is devoted to the question of whether the distinction between the two domains is reflected in neural activity.
Thus, a distinction akin to that between Sentence Grammar and Thetical Grammar is also made in some psycholinguistic studies on comprehension where a contrast between propositional representation and discourse model is made,[18][19] and in neurolinguistic discourse analysis there is a related distinction between referential and modalizing speech.
[20][21] In other frameworks, specific manifestations of the distinction are highlighted, such as that between microgrammar and macrogrammar,[22] or between an analytic and a holistic mode of processing,[23] or between conceptual and procedural meaning in the theory of Relevance Grammar.
