What's the Other One?

In some languages, you have things that look like an applicative affix that also does duty as a causative sometimes. I've seen running across that more than once. So there's something interesting going on there. And so then you end up with this, with this grammar that has like all these different things, you know, that your conlang does. And then when you go to do a translation, it uses like, youknow, quarter of them. Right. Oh, and I did remember though, the other thing, the other question that you have to be sure to answer when you're doing an applicative is you need to consider how it interacts with your other valency
