There's a whole category of cmavo, BAI, to add place structures to words that lack certain ones, and is often used by others to explicitly label places. So you have to memorize a list of about one hundred additional words, over and above the selbri themselves.
In all honesty, recalling the place structures isn't all that difficult, once you start working in the language. I idea of place structures in a deeply embedded feature of the language, which simplifies utterances over using expilict BAI tags.
