It is proposed that the response token Right, in one important use, is a marker of epistemic dependency between two units of talk by a prior speaker, and that this talk has progressed the understanding by the Right producer of a complex activity involving much information transfer. Two other Rights as response tokens are considered: as an epistemic confirmation token similar to That's right, and as a change-of-activity token similar to Alright/Okay. In addition, Right is shown to be different from other response tokens, including the news receipt Oh, newsmarkers such as Really?, and continuers and acknowledgment tokens such as Mm hm and Yeah.
