長崎県本土西南部方言の動詞テ形における形態音韻現象

要旨

In the dialect of the South-West Region of the Mainland in Nagasaki Prefecture, there are two te-forms in the verb conjugation system: (1) the form in which [te] or [de] appears, corresponding to te in standard dialect. (2) the form in which soku-on or hatsu-on appears, corresponding to te in standard dialect. Furthermore, all verbs are divided into two groups, depending on the difference of the stem-final segment, as follows: (a) verbs which have the form (1) and (2). (b) verbs which have the form (1) only. This phenomenon (called the "Te-form Phonological Phenomenon") can be adequately explained by deleting not /te/, the underlying te-form suffix, but /e/ of /te/. Furthermore the phenomenon I describe in this essay is related to onbin (sound euphony) and ra-gyo godan-ka (transformation into r-stem verbs) of the vowel-stem verb. In this essay, I studied this phenomenon in the dialects of Mogi, Sanwa, Nomozaki region and Nagayo-cho. It becomes clear that [te] or [de] appears in the Sanwa, Nomozaki, and Oka-go (in Nagayo-cho) dialects (called "Non-Te-form Phenomenon Dialects"). Soku-on or hatsu-on appears in the Mogi dialect (called the "Whole-Te-form Phenomenon Dialect"). [ʧ] or [ʤ] appears in the Hongawachi-go (in Nagayo-cho) dialect (called the "Pseudo-Te-form Phenomenon Dialect"). The discovery of the Whole-Te-form Phenomenon Dialect is the key to the problem of the formation of Te-form Phonological Phenomenon.
