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. 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.
