Infixes in 'Si' Verbs

[Maweya tswonyu]

Hi there, just a quick infix based question:

in verbs made by using the generic 'make/do' verb 'si' (eltu si, kavuk si, etc.) in which word are the infixes placed?

for example, would 'i betrayed him' in na'vi be 'oel poanti kavuk sami' or 'oel poanti kamavuk si'

thanks.

Kaltxì!

As i know the infixes go to the "si", so "kavuk sami" should be ok.

thanks, this has been bugging me for weeks

This also happens with compound words that are verb+something to make a verb.

Feeding = yomt<er>ìng, not *yeromtìng,

Prefered = nuln<ol>ew, not *nolulew

The infix always goes into the actual verb, never into a word that was not a verb to begin with.
