A historical change in which, as to the attributive and classical imperfective forms of upper and lower bigraded conjugations, the ending "-uru," "-ure" became "-iru," "-ire"respectively and finally developed into inflected forms similar to those of upper and lower bigraded conjugations is called a change of two-tier conjugation verbs into one-tier.
