 What are pure indexicals? Roughly, they are expressions the reference of which appears to co-vary with certain very regular aspects of the contexts in which they are used. Here, ‘context’ should be understood as incorporating, inter alia, a speaker, hearer, time, and place. In contrast, the reference of ‘impure’ indexicals is supposed to be more difficult to characterize in terms of picking out some distinct, repeatable feature of a context. While both the existence and the significance of this distinction are controversial (see the entry on  indexicals  for further discussion; see also Radulescu (2018)), examples of each sort of term—should the distinction prove both real and significant—typically are not. Standard examples of pure indexicals include ‘I’, ‘here’, ‘now’, and arguably ‘you’. The list of impure indexicals, on the other hand, is generally agreed to include ‘this’, ‘that’, ‘he’, ‘she’, and ‘it’.
