Vord paradigm tool

[pfeaster]

This prefix-stem-suffix system has been proposed for several decades, if I remember correctly, but has it allowed any progress?

I don't believe there's just one such system, but if you take all the proposed systems together as a group, then sure, I'd say they have -- if you count the ability to predict which word structures will or won't occur, with a respectable degree of probability, as "progress."

Of course the resulting paradigms might be frustrating if they don't match a favored hypothesis.
