Topic summary
indexical
Extracted from the Wikipedia article Indexicality.
Words and expressions in language often derive some part of their referential meaning from indexicality. For example, I indexically refers to the entity that is speaking; now indexically refers to a time frame including the moment at which the word is spoken; and here indexically refers to a locational frame including the place where the word is spoken. Linguistic expressions that refer indexically are known as deictics, which thus form a particular subclass of indexical signs, though there is some terminological variation among scholarly traditions.
