I'd ideally like to ask this question on the formal Stack, but fear it may deemed too broad.
I seem to be having trouble forming meaningful questions for this Stack because my enthusiasm and regard for the field (which is profound) exceeds my knowledge by orders of magnitude.
I know what I think linguistics is. I know what a google search returns, and what Wikipedia says. I assume could read the abstracts of a bunch of research papers to find out what any given scholar has to say. However, this strategy was not helpful when I was trying to understand the scope of Combinatorial Game Theory (CGT) some years ago. Demystification required engaging in dialectic with a distinguished scholar in the field (whose name I only withhold to avoid damaging their reputation by association with a disreputable individual such as myself;)
What I came to ultimately understand about CGT is that the scope of the field seems to be defined by the capability of mathematically analyzing a given model. (Thus poker was not considered to be within the original scope of the field, but recent work has validated the efficacy of combinatorial techniques in regard to that particular game.)
To that end I am hoping to engage in dialectic with scholars of Linguistics to get a working definition and gauge different perspectives.
