 note = {琉球方言のハ行子音 p 音は，日本語の文献時代以前に遡る古い音であるとの見方がほぼ一般化されている。この p 音についてΦ＞pによって新たに生じた可能性があるということを現代琉球方言の資料を用いて明らかにする。基本的 に五母音の三母音化という母音の体系的推移に伴って，摩擦音Φが北琉球方言では p，p^?へと変化し，南琉球方言では，p，fへと変化して現在の姿が形成されたと考える。従来の研究に従い，五母音時代を起点にするのであれば，ハ 行子音においても起点としてΦを設定しても問題はないと考える。そして，この体系的変化と連動してワ行子音においてもw＞b，の変化が起こったとみる。また，ハ行転呼音化現象や語の移入時期という側面からもp音の新しさについて考察する。内的変化として（Φ＞pが起こり得る傍証としてkw＞Φ＞pの変化傾向がみられる語も示した 。, There is a consensus that phonetically notated "p" with the consonantal valuation of [h] dates back to times before any written records were kept. I intend to demonstrate through the data I gathered during my field research trips that the derivation of the phonetically notated "p" is possibly linked to the phonetic transitional process described as [Φ]>[p]. The same process seems to be also related to the vowel shift that resulted in a decrease in the number of vowels employed in the Ryukyu Archipelago from five to three, which yielded [p] and [p^?] in Northern Ryukyu and [p] and [f] in Southern Ryukyu dialects, respectively. If the five-vowel era is granted as the originating point in the consonantal phonetic shift, then, premising [Φ] as the starting phonetic value of the consonantal valuations related to /h/ seems quite reasonable as well. The same phonetic shift also seems to have entailed a process that can be described as [w]>[b]. In view of such phonetic transition and the presumed contemporaneous introduction of relevant vocabulary into the region, I also focus on the relative recentness of the occurrence of the phonetically notated "p". As further elucidation of the phonetic transitional process [O]>[p], which most likely took place in the region, I also bring attention to some words that evidently demonstrate the transitional process [kw]>[Φ]> [p].},
