| In Middle Japanese the [p] sound, which had once disappeared before Old Japanese, appeared again but as it paralleled [?], it was treated as a newly-introduced phoneme/p/, independent from [?] (which is referred to as a phoneme/h/). |
中世日本語には上代までに一旦消えた[p]が再び現れたが、[?]と並立することから[?] （音素/h/としておく）とは異なる、新しく導入された音素/p/として扱われる。 |
