A cohesive device used to refer backwards and forwards within a text, and sometimes to refer to something outside the text. See anaphoric, cataphoric and exophoric.
Referencing is the use of pronouns, possessivepronouns, possessiveadjectives, demonstratives (this, that, these, those, here, there) and definite articles (the) to refer to something or someone that is mentioned elsewhere in the text, or in the case of exophoric referencing, outside the text.
