The polyfunctionality of which in Övdalian

open access: yes, 2015
The Övdalian wh-word ukin has a variety of syntactic uses, spanning from the canonical use as personal pronoun (‘who’) to predicative property querying item (‘what … like’) and polarity item introducing both main and embedded clauses. In this paper the various uses will be described and discussed, and it will be argued that the polyfunctionality of ...

The polyfunctionality of 'still' expressions

open access: yes
Expressions from the semasiological domain of phasal polarity (ʻstillʼ, ʻalreadyʼ, etc.) tend to be highly polyfunctional, with their various uses often extending into a wide range of other linguistic domains, both time-related and non-temporal. Yet these patterns have hitherto been investigated mostly for individual languages or smaller groups.
