This article focuses on the similarities and differences between spoken and signed language community interpreting (CI). After a brief overview of the various terms that are generally used in the relevant literature – albeit inconsistently – to categorize various sorts of interpreting (type, mode, setting), we examine a number of typologies of interpreting events that have been developed in order to allow for a more complex categorization of such events. A brief outline of the history of research into spoken and signed language CI is complemented by a short description of the similarities and differences between spoken and signed language CI. The article also discusses various examples of research methods that have been applied to spoken and signed language CI.
