Given two be’s, how do they Agree?

This squib contributes to the literature on intrusive-be constructions in English, examples of which appear in (1). Notably, there are two main sub-types, commonly referred to as double-be (la) and single-be (lb) constructions, which together have been termed intrusive-be constructions (Massam 2013). In this squib, we focus on double-be constructions, in which two instances of be (bel and be2) appear adjacent to each other as in (la), and we examine the tense and agreement forms that be can take in such constructions.
