The purpose of this study is to investigate the progress of “potential verb”, “reru・
rareru” and “kotogadekiru” after the Meiji period.
First, I counted the “potential verb”, “reru・rareru” and “kotogadekiru” that had been used in the selected fourteen literary works. And then I analyzed the expective value's deviation that were calculated by the incidence rate and the expected value of the total usage rate.
