Non-prototypical usages of the Lugwere causative extension

Lugwere is an under-studied Great Lakes Bantu language spoken in Eastern
Uganda, and this paper presents a thorough investigation of non-prototypical
 usages of the causative suffix in Lugwere, including usages that would be classified
as applicative. Causative and applicative isomorphism has been reported for a
range of language cross-linguistically (Peterson 2006), and within Bantu, reflexes
of the inherited Proto-Bantu causative *-ici has instrumental usages in a handful of
languages (Jerro 2017, Schadeberg & Bostoen 2019). This is also found in Lugwere,
alongside examples of a comitative usage that has not been reported elsewhere.
There are also examples where the causative suffix does not affect either the
semantic or the syntactic argument structure.
