Tangut character 17FDA

It is a Tangut character associated with adding or attaching. Li Fanwen's 2008 Tangut-Chinese Dictionary indexes it as entry 2856 with the Chinese character 坿, a rare written form related to 附. The Chinese glosses include adding, attaching, or depending on something; treat this as a clue to the Tangut character's sense, not a Chinese reading.

The Tangut script, also called Xixia, was created around 1036 under the first emperor of Western Xia to write the Tangut language. It served official, private, and religious writing, including books, inscriptions, manuscripts, and Buddhist sutras. It stayed in use after the state fell to the Mongols, then became obsolete by the end of the Ming dynasty. It was rediscovered in the late 19th century; N. A. Nevsky's work in the early 20th century helped scholars decipher it.

Why does 𗿚 look Chinese?

Tangut is a distinct script with Chinese-like square forms. That visual style can look familiar to a reader of Chinese, but 𗿚 writes Tangut, not Chinese. Chinese literacy alone will not decode it.

Traditional Tangut writing ran downward in vertical columns arranged from right to left. Modern scholarship also prints it horizontally from left to right, so layout depends on the text.
