Vague stuff: Cose as a general extender from Latin to Italian

This paper investigates cose (pl. of cosa ‘thing’) as a general extender (GE) and marker of non-exhaustiveness from Latin to contemporary Italian. The
study employs three corpora: CODIT, LIP/VOLIP and KIParla. We show that the frequency of cose-GEs dropped in 16th c., when they started being
perceived as colloquial. In old Italian, cose-GEs already expressed nonexhaustiveness in list constructions and, until late 17th c., were frequently
specified by a nominal modifier, which however was uninformative to identify the category. Contemporary spoken Italian results confirm the role
of spoken language in developing structures encoding non-exhaustiveness, also in a dialogical sense. Moreover, recent data show an increase in
frequencies of cose-GEs. Finally, we found more variability compared to the structure usually identified for GEs.
