Abstract

Our main concern is to provide a complete picture of how coTAGs, as a particular variant within the general framework of tree adjoining grammars (TAGs) be captured under the notion of abstract categorial grammars (ACGs). coTAGs have been introduced by Barker (2010) as an "alternative conceptualization" in order to cope with the tension between the TAG-mantra of the "locality of syntactic dependencies" and the seeming non-locality of quantifier scope. We show how our formalization of Barker's proposal leads to a class of higher order ACGs. By taking this particular perspective, Barker's proposal turns out as a straightforward extension of the proposal of Pogodalla (2007), where the former in addition to "simple" inverse scope phenomena also captures inverse linking and non-inverse linking phenomena.
