After that, e and ye merged into ye in the 10th century, before eventually evolving back to e.Frellesvig, Bjarke (1995). A Case Study in Diachronic Phonology: The Japanese Onbin Sound Changes. Aarhus University Press. p. 73
Edo period–Meiji period In the Edo period and the Meiji period, some Japanese linguists tried to separate kana e and kana ye again. The shapes of characters differed with each linguist. 𛀁 and 𛄡 were just two of many shapes.
They were phonetic symbols to fill in the blanks of the gojūon table, but Japanese people did not separate them in normal writing.
