Ye (kana)

Japanese people separated e and ye in Man'yōgana, early Hiragana and early Katakana.

Man'yōgana[2]

• e
  • 愛、哀、埃、衣、依、榎、荏、得
  • 可愛
• ye
  • 延、曳、睿、叡、盈、要、縁、裔、兄、柄、枝、吉、江

Hiragana[3]

• e
  • (Undiscovered)
• ye
  • etc.

Katakana[4]

• e
  • 𛀀 etc.
• ye
  • エ etc.

After that, e and ye merged into ye in the 10th century, before eventually evolving back to e.[5]

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 gojuon table. Japanese people didn't separate them in normal writing.
