The present papers deals with grammaticalization in Ancient Egyptian and Coptic. After introducing the general concept, various patterns of grammaticalization are described. These include the development of the negation j(w)n (#) > ⲁⲛ, the evolution of the auxiliary j r+ and the subject element of nominal sentences, and the development of marking for indefiniteness. In addition, two case studies of opposite grammaticalization processes in Coptic are contrasted.
