  Indexicals are commonly called context-sensitive expressions (or context-dependent expressions) but the two terms tend to be used differently. The term ‘indexical’ tends to be restricted to simple expressions, such as ‘I’ and ‘today’. The term ‘context-sensitive’, however, is commonly applied both to simple indexicals and to complex expressions that contain simple indexicals, for example, the definite description ‘the dog she is looking at’, the verb phrase ‘sat next to me’, and the sentence ‘He is standing’.
