Something strange to me in the gismu list around line 952,> pu'i pus can and has modal > aspect: can and has; demonstrated potential...and just a few lines later,> punji puj pu'i put x1 (agent) puts/places/sets x2 on/at > surface/locus x3 ...Is that not contradictory uses of pu'i? How can it be both a rafsi and a cmavo?
It looks a little confusing in this context, but you will always know the difference when you see it in use. A cmavo is always its own word (or in a cmavo cluster, which is several cmavo lumped together with no written spaces). On the other hand, a rafsi is always part of a lujvo and can never appear as its own word.
There are several sets where a CVV word is both a cmavo and a rafsi, although many of them have simmilar meanings.
I can see som ambiguity if you have {pu'ibroda} -- can this break into both {pu'i broda} and be an alternate for {pujbroda}? Or would we need {pu'irbroda} for the second meaning?
