What 𐋩 means
It adds nine to the other signs. Write values from largest to smallest and add them: 𐋪𐋩 = 19 (ten plus nine). The regular Coptic letter Ⲑ also represents nine; here, that value has its own cursive numeral sign.
The set took shape during the 10th century for administrative use in Egypt’s Coptic-Arabic community, where Coptic and Arabic writing met. It also appears in astronomical texts; Arabic writers called it ḥurūf al-zimām (“register letters”).
Historical and specialist: use 𐋩 for this Coptic numeral; include 9 if readers may not know the notation.
