The present contribution starts from Goldberg and Perek’s (2019) analysis of gapping within a constructionist framework. The authors promote their analysis as surpassing non-constructionist takes on gapping and ellipsis more generally. In particular, they claim predictive power. That this is not the whole truth is explained in detail in this contribution. It is shown which predictions can be made from their perspective versus from a generative perspective and it is discussed whether they are borne out. Furthermore, I highlight how the predictions relate to the fundamentals of the respective theories and, as a consequence, how they differ in kind.
