This book explores verbal and non-verbal communication from a social
anthropological viewpoint, drawing on ethnographic data from fieldwork
in East Africa. It gives an overview of developments since the 1960s in
the anthropology of language use and how these have influenced the
author's thinking. The volume makes the argument that language and other
forms of communication involve semiotic transactions between
interlocuters; that such communicative exchanges do more than convey
information; and that they give identity to the recipients of such
transactions who reciprocate by defining speakers. The density and
situational totality of such semiotic exchange can moreover be regarded
as a kind of materiality, both in terms of their impact on social
interaction and in how interlocuters interact bodily as well as verbally
among themselves.
