This reference grammar provides a novel and detailed overview of Old Nubian, an extinct Nilo-Saharan language written in the Nubian kingdom of Makuria between the 8th and 15th centuries CE. Including more than 700 glossed examples sourced from manuscripts and inscriptions covering the entire written record, this standard work treats Old Nubian syntax, topic/focus constructions, subordination and coordination, verbal morphology including person, aspect, tense, pluractionality, affirmation, and negation, nominal morphology, derivation, and phonology. The grammar is aimed both at scholars working in the fields of Nubiology, Egyptology, and Near Eastern Studies curious to gain a better understanding of one of the lesser studied languages from the medieval period, and linguists interested in one of the few historical languages of which written records have survived on the African continent.
