A reflexive pronoun is a pronoun that is preceed by the noun or pronoun to which it refers (its antecedent) within the same clause. In generative grammar, a reflexive pronoun is an anaphor that must be bound by its antecedent (see binding). In some languages, there is a difference between reflexive and non-reflexive pronouns; but the exact conditions that determine whether something is bound are not yet well defined and depend on the language in question.
