Huh, interesting question! I don’t know the answer to this, and I don’t really have time to research this properly just at the moment, but here’s a couple of pertinent observations in the meantime:willm wrote: ↑Thu Feb 04, 2021 11:32 am I’m sorry if this has already been addressed in this thread, but I couldn’t find mention of it. Does anyone know if the objects of adpositions in ergative-absolutive languages tend to be in the ergative case or the absolutive case? I would expect the absolutive to be used, since it is the default and includes the accusative, or perhaps for it to depend on the semantics of the adposition. This would only be apparent, I would expect, in languages that use affixes to mark case. Georgian and Basque seem to mostly use additional cases, but I’m curious about what is usual in languages that use the ergative or absolutive case.
- Adpositional complements tend to be marked; the more marked case in an ergative–absolutive system is the ergative, suggesting that they would be marked with the ergative.
- Ergative case is very often syncretic with peripheral cases such as instrumental and ablative.
(Also, you say that the absolutive ‘includes the accusative’, but that isn’t quite correct; the absolutive case tends to correspond to the nominative case instead, since both are unmarked.)
