Among the idiosyncratic aspects of ancient Egyptian life and culture, Egyptian writing has long received particular attention—not only in recent academic discourse, but already in Antiquity. Compared to other writing systems, hieroglyphs and, to a lesser extent, their cursive derivatives, hieratic and Demotic, demonstrate extraordinary potential to express different aspects of both meaning and sound when employed beyond their conventional use. In its particular iconicity Egyptian writing, especially hieroglyphic writing, works even outside the framework of language and shares common features with Egyptian art. In the textual record non-standard creative writings highlight the potency and multidimensionality of Egyptian writing through the interplay of meaning, sound, and icon. The contours of the phenomenon are here outlined and the main characteristics of non-standard creative writings defined according to their varying forms and functions. In conclusion, a system of classification, as provided here, can further our understanding of the multitude of forms and functions involved, and thereby enhance appreciation of the potency of Egyptian writing.
