For Proto-Søkkli I am in bad need of ideas for different kinds of derivation, as I have only a few such derivation paths, and find myself unnecessarily making noun-verb doublets where there really probably should have one derived from the other.

The current paths I have are agent noun from verb, gerund from verb with zero-derivation, adjectival verb from noun, and comparative, superlative, and elative from adjectival verb (which I do treat as derivation rather than inflection), diminuitive and augmentative of noun, and all different kinds of verbal and nominal compounding, and I am considering on adding result noun from verb. However, I do need more derivational paths than that.

Any ideas?
