Did you make the breakfast?

Glossary: 

1. ti-sun: you, 2nd person singular nominative (NOM). ti- 'subject case marker for specific person'; the root is sun 'you, 2nd person singular'. 
2. a: ligature (LIG)
3. na-k<em>esa: cooked, actor voice (AV). The root is kesa 'cook'. 
4. tua: oblique (OBL) case marker
5. tja: our, 1st person plural genitive (GEN), usually bound, but seems also to serve as a general demonstrative.

*I had a conversation with kivi, a native of sinvaudjan and a Paiwan language teacher, about kenamain. I suggested, without much evidence, that this word may derive from a three-fold conjugation: k<en>a(n->m)-in. -en- and -in are two undergoer voice (UV) case markers and n becomes m for easier pronunciation. I now feel my guess may be too far-fetched because I cannot find an example where the root kan is used as UV.
