Most of the monosyllabic negators in Southern Min dialects have maintained their usages from ancient Chinese. Some of them, however, have undergone unique semantic changes, such as shift to a different part of speech and grammaticalization depending on geographical distribution. Semantic cross-linking led to concatenations while used in context. The polysyllabic negators also reflect geographical characteristics. Overall, this article classifies the negators into three groups: Coastal Min, Inland Min, and Island Min types. This article attempts also to explain the motivations for the patterns of their semantic changes: language itself, subjective, and objective worlds.
