This article classifies individual lexemes in Chinese dialects into four categories: popular, learnèd, colloquial, and literary. Popular and learnèd refer to the origins of a word: whether it has been transmitted orally or learned in an educational context. Colloquial and literary refer to usage. The traditional Chinese terms for distinguishing character readings, wén 文 and bái 白, literally ‘written’ and ‘spoken’, do not correspond neatly to the four categories that are proposed here. This article illustrates the differences between all six terms, mainly by using standard Mandarin and Běijīng dialect, and secondarily by using words from Mĭn and other dialects.
