The missing piece in the jigsaw puzzle

Abstract

Abstract Past research approached the origins of the Coptic alphabet sociolinguistically and empirically. Neither can fully explain the comparatively sudden and fundamental change from a supraphonemic to a phonemic writing system for Egyptian around the second century AD. This paper adds the cognitive-linguistic concept of the grain size of a writing system to the picture. In essence, by the second century, sound changes in Egyptian had resulted in a phonological structure of the language that mapped more easily onto a phonemic writing system than previous stages of the language. This coincided with socio-political developments favouring the Greek alphabet. As a result, multiple writing systems, which shared the underlying structure, alphabetic, and model, the Greek alphabet, emerged. Eventually, one of these prevailed, the Coptic alphabet.
