“…Grammaticalization is more strictly focused on grammatical phenomena either general: tense and aspect (Dahl, 1985;Bybee and Dahl, 1989), modality (Traugott and Dasher, 2004;Ziegeler, 2011), spatial orientation (Heine, 1997;Sipocz, 2005) or specific: copulas (Devitt, 1994;Katz, 1996), particles of phrasal verbs (Brinton and Traugott, 2005;Los, 2006), passives (Haspelmath, 1990;Wiemer, 2015), demonstratives (Diessel, 1999;Catasso, 2011), articles (Himmelmann, 1997;Mulder and Carlier, 2011), adverbs (Heine, 1991;Haspelmath, 1997;Killie, 2014), prepositions (Seppänen, Bowen and Trotta 1994;Schwenter and Traugott, 1995;Akimoto, 1999;Hoffmann, 2005).…”
