In grammar, a reflexive verb is, loosely, a verb whose direct object is the same as its subject; for example, "I wash myself". More generally, a reflexive verb has the same semantic agent and patient (typically represented syntactically by the subject and the direct object). For example, the English verb "to perjure" is reflexive, since one can only perjure "oneself". In a wider sense, the term refers to any verb form whose grammatical object is a reflexive pronoun, regardless of semantics; such verbs are also referred to as pronominal verbs, especially in grammars of the Romance languages. In the Romance languages, the pronominal verbs is a parent category with reflexive verbs as only one of its sub-categories. Other kinds of pronominal verbs are reciprocal ("they killed each other"), passive ("it is told"), subjective, idiomatic. The presence of the reflexive pronoun changes the meaning of a verb, e.g. Spanish "abonar" to pay, "abonarse" to subscribe.
