The signals of connecting and stopping are necessary to make a successful communication. In case of Japanese sentence, many signals of connecting and stopping are appeared. we can use Chinese characters and Kana of Hagyou. In case of ancient Japanese we also use many signals to show connecting and stopping. For example we use different Kana, it depends on spelling location and we also use Sumitugi. In Japanese inscription signal of first spelling are appeared as well as those of non-first spelling. In modern Japanese we usually use Dakuon, TYouon, Sokuon and Haneruon as signals of connecting. they have a important role to show connecting. In case of ancient Japanede some Kana should appear only after first spelling. and Renmen shows as non-first spelling, too.
