What explains the difference in black and non-black use of the n-word? In the mouths of black speakers the n-word can take on friendly, or at least benign significance. This chapter will be concerned with providing an explanation. First, it will present three accounts—i.e., the Ambiguity thesis, an Expressivist account, and an Echoic account, ultimately arguing that none of them is satisfactory. Next, it introduces the concepts of a speech community and a community of practice and explicates their roles in in-group uses. It concludes with a distinction between calling and addressing, introduced by Geneva Smitherman, to explain the specific illocutionary act undertaken by in-group members that allows for endearing or neutral uses of slurs and argues that membership in the relevant community of practice licenses one to access the relevant illocution.
