“…Usage-based SLA has documented the bottom-up, exemplar-based nature of learning in the form of e.g., verb-argument constructions (Ellis and Ferreira-Junior, 2009;Römer and Berger, 2019), object transfer constructions (Year and Gordon, 2009), can-constructions (Eskildsen, 2009), auxiliary do-constructions (Eskildsen, 2011); negation constructions (Eskildsen and Cadierno, 2007;Eskildsen 2012), motion constructions (Li et al, 2014;, relative clauses (Mellow, 2006), question formation (Eskildsen, 2015), French c'est and Swedish det är constructions (Bartning and Hammarberg, 2007), German gehen and fahren (Roehr-Brackin, 2014), L2 Finnish evaluative constructions (Lesonen et al, 2020a), and epistemic verb constructions in L2 Norwegian (Horbowicz and Nordanger, 2022). In the longitudinal work, the research focuses on the extent to which L2 construction learning is exemplar-based, i.e., moving along a trajectory from specific instances to increased productivity and schematicity within single constructions.…”
