A deictic [pronounced dyke- tic or dake- tic] is a word specifying identity or spatial or temporal location from the perspective of one or more of the participants in an act of speech or writing, in the context of either an external situation or the surrounding discourse. In other words, it suggests the phenomenon wherein understanding the meaning of certain words and phrases in an utterance requires contextual information. So a deictic is a word that has a fixed semantic meaning, but has a denotational meaning that constantly changes depending on time and/or place.
