In English grammar, a referent is the person, thing, or idea that a word or expression denotes, stands for, or refers to. For example, the referent of the word door is the object door.. Referring words are words, such as pronouns, that point back to other items in a text (anaphoric reference) or (less commonly) point ahead to a later part of the text (cataphoric reference).
