Well, you don't need to adhere to pure linguistics for your conlang with regards to causatives or applicatives etc, you can just claim your conlang has something that "has approximately or implies these meanings", as natlangs also often don't neatly fit within linguistics terminology sometimes. For example, in that other natlang that I natively speak, there is an affix that has a similar effect that you propose - let's just call it the K-suffix here in the gloss.Ahzoh wrote: ↑Tue 02 Oct 2018, 13:17Although I am not looking to derive a pure morphological causative but have a single applicative that can convey, comitative (together with), adjutative (on behalf of), causative (because of), and superlative meanings. But that seems to require the promoted object to be in cases other than accusative, which defeats the point.
* Comitative (~instrumental)
1SG ACT-key-K door = I locked the door with a key
* On behalf of (~pseudo-trigger mechanics)
1SG ACT-read-K 3SG book = I read a book for you
* Causative (~transitivity elevator)
1SG ACT-jump-K ball = I made the ball jump
* Superlative (~attribute-giver)
1SG ACT-long-K 3SG = I lengthen it
The left shows what you wanted, and the right (bracket) shows what that other natlang that I speak does, which seems rather close. If it pleases you that such feature or idea is attested in natlangs, then...
You got ANADEW-ed.
