Abstract
Ragyō-godanka is a phenomenon in various Japanese dialects, in which a vowel-final verb stem behaves morphologically the same as a consonant-final verb stem ending in /r/ (e.g., miran /mir-an/ ‘do not see’; Shība Village dialect, Miyazaki Prefecture). This paper describes the dialectal variation of the verb stem and suffix conditions under which ragyō-godanka occurs and then formulates these variations as implicational hierarchies with regard to stem-final vowels, stem mora counts, and suffixes. Finally, it elucidates the motivation for the value ordering of these hierarchies as reflecting the frequencies of word forms.
