Khitan small-script character

𘲣 is a sound sign in Khitan small script; proposed readings include iû, ou and iu, but none is settled. Sound signs combine into word blocks. The script was made to write Khitan; accounts date its creation to the 920s, though a 2026 study argues standardization came later. The oldest securely dated text is a 1051 tomb inscription; Jin banned Khitan writing in 1191, and Jurchen writing later adapted it.
