The Pearl in the Palm or the Timely Pearl (Tangut: 𗼇𘂜𗟲𗿳𗖵𘃎𘇂𗊏; Chinese: 番漢合時掌中珠; pinyin: Fān-Hàn Héshí Zhǎngzhōngzhū) is a bilingual glossary between the Chinese and Tangut languages. It survives as a single complete copy of a 12th-century woodblock printed book that was discovered in the Tangut city of Kharakhoto. In addition, a single page from a different copy of the same edition of the Pearl in the Palm was found at the Northern Mogao Caves in 1989.[1] The book transcribes the pronunciation of Chinese words into Tangut characters, and the pronunciation of Tangut characters into Chinese characters, and so is a very important source for Tangut historical phonology, and was the primary source before the publication of monolingual Tangut dictionaries.
