The monosyllabicization of Old Chinese and the birth of Chinese Writing: A hypothesis on the co-evolution of the Chinese language and its writing system

The invention of the Ancient Chinese Writing System (henceforth ACWS) is a significant event in world history. In this paper I put forward a hypothesis on the co-evolution of the Old Chinese language and its writing system (ACWS). I argue that the invention of ACWS bears a strong correlation with the linguistic evolution, more specifically, the monosyllabicization, of Old Chinese. In other words, ACWS might never be invented if monosyllabicization had not occured in Chinese. The paper is organized in the following way. First, we discuss the reason why a subsyllabic writing system was not invented for Old Chinese (section 2). Next, we discuss the nature of the rebus principle in ACWS (section 3), and its correlation with morphological alternations (section 4). Then I argue that monosyllabicization of Old Chinese is a precondition for the rebus principle, which is crucial for the birth of ACWS (section 5). Lastly, I discuss the implication of the hypothesis for the study of Old Chinese (section 6).
