RT Journal Article T1 A functional model for the tag question paradigm: the case of invariable tag questions in English and Portuguese A1 Gómez González, María de los Ángeles A1 Silvano, Purificação K1 Tag questions K1 Invariable question tags K1 British English K1 European Portuguese AB While research has mostly focused on the pragmatics of variable tag questions, fewer studies have explored invariable tags, either for their own sake or in contrast with other tag types within and across languages. It will be argued that invariable tag questions are as much part of the tag question system as variable tag questions, and that a unified functional model needs to consider both types in order to compare function-to-form mappings and reveal language variation, as well as the factors motivating their use. This study proposes one such model comprising eight functional types of tag questions, i.e., informational, affective, challenging, hortatory, facilitative, focusing, phatic and regulatory, in relation to four clusters of grammatical, dialogic, generic and sociolinguistic features. Based on the analysis of 539 invariable tag questions in British English and European Portuguese, results show that the constructions are more frequent and functionally varied in Portuguese (N = 397 vs. 142). In addition, based on statistical analyses, corresponding multi-feature prediction models are obtained for the proposed functional types of invariable tag questions in the two languages under inspection, thereby uncovering novel contributions to the pragmatics of invariable tag questions within the tag question paradigm PB Elsevier YR 2022 FD 2022 LK http://hdl.handle.net/10347/29013 UL http://hdl.handle.net/10347/29013 LA eng NO Lingua 272 (2022) 103255 NO The research was funded by the Spanish National Research Agency (FFI2013-40517-P; 2019-PN145) and the Xunta de Galicia (GRC2015/002 GI-1924; ED431C 2019/01), whose financial support is hereby acknowledged DS Minerva RD 24 abr 2026
