Subjectification and attenuation in the conceptual schema of the Catalan modal verb deure with evidential meaning

Resumen
- This corpus-based study focuses on the rise of evidential meanings of Catalan modal verb deure ('must') from its original deontic meaning (between the 12th and the 16th centuries). We have been able to analyse the process of grammaticalization with absolute reliability thanks to the applied technology of the Corpus of Old Catalan (CICA and CIGCA), in which linguistic variation is quite representative. This study takes a cognitive perspective (Langacker 1987, 1991, 1999, 2006; Pelyvás 2000, 2006) that provides us with the tools to set up a semantic network and the paths of semantic change.
