Tangut Component 454

It is a component used to describe larger Tangut characters.

Unicode uses Tangut components to show how larger characters are built and to help readers find them in dictionaries. A component can have different meaning-related or sound-related roles in different characters, so 𘧅 has no single word translation when it stands alone.

Historical accounts date the Tangut script's creation to 1036–1037, for the Western Xia state's records and translated texts. The earliest transmitted Tangut document dates to 1072. Tangut writing continued after Western Xia fell in 1227; an inscription from 1502 records later use. These dates concern the script's history, not this component's computer encoding.

Why is it called a component?

Because it helps describe or index a larger Tangut character.

Component lists help organize dictionary lookup. Older dictionaries of Western Xia, the Tangut state, ordered entries by sound; modern Tangut dictionaries use different component-and-stroke systems. Unicode brings together component inventories used in Chinese, Japanese, Russian, and English dictionaries and publications. The number 454 is a modern lookup label, not an ancient meaning. Tangut writing used Chinese writing as a conceptual model but is a distinct script; proposed Khitan influence remains debated.
