“…The primary focus of the paper is related to the English morpheme -ing, where adjacent -ing affixed forms are sometimes, but not always, ungrammatical, as first described by Ross (1972). 1 This phenomenon has received considerable attention in the literature (with subsequent additional descriptions and discussion by Milsark (1972), Emonds (1973), Pullum (1974), Milsark (1988), Emonds (1991, Yip (1998), Pullum & Zwicky (1999), Milsark (2006), Richards (2010), Nevins (2012), along with related discussions by Menn & MacWhinney (1984), Borer (1990), Hiraiwa (2014), Punske (2016), among others, but, as I argue, still lacks a satisfactory solution. I argue that, by examining nominalizations, which are commonly and/or explicitly ignored within this literature, a solution becomes apparent.…”
