I've been looking for a way to factor the concept of representation in a useful way, since I figured that would also help develop the human-indifferent account of emotions (i.e. as actions in response to similarity observations) that Sika has been sorely lacking, and I think I found the solution:

-tci - an intelligent response (to -)

To be clear, -tci can refer to any kind of response that indicates observation of the given thing by some sort of intelligent thing.

This lets us derive a few useful words:

-rtci - motivation (possibly incorrect) of a given action (what it is an intelligent response to)

-tcirfi - representation; intelligent response helper

-tcikau - more intelligent response, i.e. one of someone/something competent (noting that -kau refers to the "interior"/sure cases of a concept)

-tcirikau - strictly intelligent response (where -ri- maximally amplifies a word)

sirtci - the motivation behind this message

I think this addition has potential, though I'm not sure it won't change in name.
