Searching for an Inuktitut etymology of the TP word 'kipisi' (to cut)

The beginning

I'm trying to find out if there could be an Inuktitut origin for the Toki Pona word 'kipisi' (to cut) like the creatrice Sonja Lang thinks herself ...

I was talking about a possible but quite uncertain Swahili origin for the word when she stepped in the convo to point out to me the following

Sonja Lang > Pite Janseke on Facebook | 17 Sept 2018

if I remember correctly, kipisi was from Inuktitut.

The confirmation

This is the information I have found so far and an Inuit etymon has been confirmed by an Academic specialized in these language and professor at the University of Chicago ...

De Pite,

What you cite is indeed Inuit, specifically Eastern Canadian Inuktitut. Kipisi is not a whole word, but the uninflected stem of a verb, just the kind of thing that would be used in a pidgin or creole language. The dictionary form of the word is the transitive verb kipijanga: he/she cuts it, kipijara I cut it, and so on. The intransitive requires the suffix -si-: kipisijuq: he she cuts, kipisijunga: I cut, and so on. In West Greenlandic the verb is kipivaa he/she cuts it; kipivara I cut it, etc. and the intransitive requires no suffix: kipivoq "he/she cuts (something), kipivunga I cut it, etc. A Greenlandic (Kalaallisut) to English (Tuluttut) app can be found by looking for "oqaatsit" on the web. Can you tell me something about Toki Pona?
