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 more broadly referred to as pronominal verbs, especially in grammars of the Romance languages. 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. There are languages that have explicit morphology or syntax to transform a verb into a reflexive form. In many languages, reflexive constructions are rendered by transitive verbs followed by a reflexive pronoun, as in English -self (e.g., "She threw herself to the floor.") English employs reflexive derivation in-idiosyncratically, as in "self-destruct". Indo-European languages Romance and Slavic languages make extensive use of reflexive verbs and reflexive forms. In the Romance languages, there are non-emphatic clitic reflexive pronouns and emphatic ones. In Spanish, for example, the particle se encliticizes to the verb's infinitive, gerund, and imperative (lavarse "to wash oneself"), while in Romanian, the particle procliticizes to the verb (a se spăla "to wash oneself"). Full reflexive pronouns or pronominal phrases are added for emphasis or disambiguation: Me cuido a mí mismo "I take care of myself" (mismo combines with the prepositional form of the pronoun mí to form an intensive reflexive pronoun). The enclitic reflexive pronoun sa/se/si/się is used in Western and South Slavic languages, while Eastern Slavic languages use the suffix -sja (-ся). There is also the non-clitic emphatic pronoun sebja/себя, used to emphasize the reflexive nature of the act; it is applicable only to "true" reflexive verbs, where the agent performs a (transitive) action on itself. The Slavic languages use the same reflexive pronoun for all persons and numbers, while the Romance and North Germanic ones have a special third person pronoun that cliticizes and the other Germanic ones do as well without cliticizing. This is illustrated in the following table for the word "to recall" (e.g., Je me souviens means "I recall",
