Robert Hopper’s work has been centrally concerned with the question of how human beings produce action in concert with each other by deploying the resources and practices used to organize talk-in-interaction (e.g., Hopper, 1988, 1989, 1992, 1999; Hopper & Chen, 1996; Hopper & Glenn, 1994; Hopper & LeBaron, 1998). The present chapter explores one facet of this process, focusing on the way in which culturally relevant understanding of the names used to identify valued objects is made visible through specific interactive procedures.
