Ilk. medial [j] became [i]; [-j-] > [-i-]
As indicated in the Comparative Tables, medial [j] (= “y”) became [i] in Ilkorin (PE19/23). There are no clear examples of this development in The Etymologies, though there are several examples where final [j] became [i]. Helge Fauskanger suggested that the primitive form of gelion “bright” might be *✶galjānā (AL-Ilkorin/gelion); if so, it would be an example of this medial development.
