Abstract
Abstract While literature on English modality has usually focused on traditional modal and semi-modal verbs, to our knowledge, no attention has ever been given to the emerging be having to (BHT) construction. Through corpus analysis conducted on GloWbE, ICE, BNC and CLMET, this article investigates the semantic differences between have to and BHT that make them distinct in the English constructicon. We demonstrate that BHT conveys meanings of contingency, reluctance and inchoativity, and propose that its recent emergence may stem from a specific functional gap within the English modal system. While have to appears to be gradually grammaticalizing with future-oriented functions, BHT seems to be renewing the original (and less grammaticalized) dynamic functions of have to. Finally, we explore the productivity of the construction across different English varieties and the reasons for its lower frequency in postcolonial varieties. The hypothesis of negative retentionism proposes that a feature that was absent in the lexifier language at the time of contact may indeed be found to be less frequently used in the contact variety at a later stage due to colonial lag.
