| Verbs comprise verbal roots, but also their variations with prefix strings of preverb particles, and secondary formations for causatives, intensives and desideratives. |
| The fact that some idioms are restricted to causatives, while others are restricted to inchoatives, lends new support to the view that the two derivations are distinct. |
| The latter are illustrated particularly by causatives such as that in We walked the horses back to the paddock, with a causative converted from an intransitive. |
| Like causatives and desideratives, denominatives follow the inflection of thematic verbs of the Present System. |
