I don't intend to create a new page for this topic—I just want to add to the causatives page. I've recently discovered the possibility of an adversative causative in Guarani (mbo- verses guero), so I looked it up, and it turns out that Japanese has one too according to one source[1], even though it's not mentioned on the Japanese grammar page.. I just did a google search, and it turned up. I don't know if other languages have it, but I haven't found anything quite yet. I'll have to check Dixon or Aikhenvald's grammars of languages. I'll need to check Dixon's "Changing Valency" book again (chapter 2) to see if he mentions any.
