The Huáyí yìyǔ (Chinese: 華夷譯語; lit. 'Sino-Foreign vocabularies') refers to a series of vocabularies produced by Ming and Qing dynasty Chinese administration for the study of foreign languages. They are a precious source of phonological information, both for the study of Chinese pronunciation and for the study of the languages in question.
The relevant works of the huáyí yìyǔ fall into four categories: A Sino-Mongolian vocabulary compiled by Huo Yuanjie (火源潔), 2. Vocabularies that were compiled and re-edited in the Siyiguan (四夷館). 3. Vocabularies prepared by the Huitongguan (會同館). 4. Qing dynasty vocabularies.[1]
