Abstract In my target paper Subregular linguistics: Bridging theoretical linguistics and formal grammar I argued that theoretical linguistics and formal grammar, despite major differences in methodology, have a lot to offer to each other, and that the recently emerged subfield of subregular linguistics provides a conduit for knowledge transfer between the two. I thank all the authors for their thought-provoking commentaries that greatly enrich the discussion that I hoped to start with the initial paper. Here I focus on some shared themes revolving around subregular syntax: the role of mappings, with Irish wh-agreement as a concrete example; the challenges of linearization, with a new Generalized Ban on Improper Movement derived from subregular limits of linearization; the importance of careful empirical analysis, including a brief discussion of existing work on gradient TSL and its empirical applications; and finally, what exactly it means to say that a specific phenomenon falls within a subregular class like TSL, and why this is orthogonal to the issue of formalisms and metalanguages.
