Literacy is a linguistic innovation characterised by the encoding and decoding of language into a system of visual signs whose relevance to daily life in most societies cannot be overstated. Understood to be both a technology and a social practice, literacy has been the subject of anthropological inquiry since the late nineteenth century, with protracted debates about its effects on human consciousness and social life. This entry tracks the development of literacy as a concept. Initially dominated by technologically deterministic assertions that literacy was a tool for sociocultural and cognitive development, anthropology would later embrace the more culturally relativistic perspective advanced by the New Literacy Studies movement of the 1980s and 1990s. This movement sought to understand how cultural logics and norms informed the development of localised literacy practices, thus creating variations of ‘literacies’ which were themselves embedded within ideologies and structures of power relations. Coming to recognise the marginalising power of standardised literacy, anthropology turned its attention to education. Anthropologists and educators have become partners in research dedicated to developing pedagogical practices that draw upon the unique linguistic resources and practices that students bring with them into the classroom to cultivate inclusivity and empowerment. The increasing prevalence of digital technologies in all aspects of daily life have challenged earlier notions of literacy, inspiring anthropologists to investigate how people draw upon multiple modalities to encode and decode meaning, thereby fundamentally reshaping our understanding of what it means to ‘read and write’.
