Tangut Ideograph 18156

It is a Tangut character; its recorded reading is not a translation.

The Unicode label Tangut Ideograph-18156 identifies the encoded character; it is not a Tangut dictionary entry. A Unicode glyph-correction note records Li Fanwen's reconstructed reading bjɨ̱. That spelling is scholarly notation for a Tangut reading, not an English word or gloss.

The same note says one manuscript may instead use 𘅇 as the first character in that pronunciation analysis. The analysis does not itself translate 𘅖 into English.

Why was Tangut writing created?

It was made for the Xixia state and its writing.

Tangut writing entered official use in 1036 for Xixia, also called Western Xia. It served state records and diplomatic documents, and carried translations of Chinese classics and Buddhist works.

After Xixia fell in 1227, Buddhist texts kept the script in use. The latest known datable Tangut materials are Buddhist pillars erected in 1502.

How are 𘄶 and 𘅖 connected?

A scholarly spelling analysis links them, not their meanings.

Fanqie (反切) is a traditional way to indicate pronunciation with two characters: the first supplies the opening sound, the second the rest. In a Tangut-Chinese dictionary analysis, Li Fanwen used the left component of 𘅖 and the right component of 𘂭 to explain 𘄶's fanqie reading.

The note says one manuscript might instead show 𘅇 as the first character in that spelling. This is uncertainty about the manuscript reading, not evidence that 𘅖 and 𘅇 are interchangeable.
