Khitan small-script character 18C05

𘰅 is a Khitan small-script sign used to write Khitan, a medieval language of northern China; as of 2026, no standalone sound or meaning is established. Traditional accounts date the script’s creation to about 925, but a 2026 study argues it was standardized later; the earliest securely dated surviving text is a 1051 grave inscription. Under Liao rule it served official records and poetry; Jurchens later drew on Khitan writing.
