Reflexive verb

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.

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 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 to avoid ambiguity: 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 here in the following table for the word "to recall" (e.g., Je me souviens means "I recall", Tu te souviens means "You recall", and so on).

	French		Danish		Serbo-Croatian
	Singular	Plural	Singular	Plural	Singular	Plural
1st person	Je me souviens	Nous nous souvenons	Jeg lægger mig	Vi lægger os	Ja se sjećam	Mi se sjećamo
2nd person	Tu te souviens	Vous vous souvenez	Du lægger dig	I lægger jer	Ti se sjećaš	Vi se sjećate
3rd person	Il se souvient	Ils se souviennent	Han lægger sig	De lægger sig	On se sjeća	Oni se sjećaju

In all of these language groups, reflexive forms often present an obstacle for foreign learners (notably native speakers of English, where the feature is practically absent) due to the variety of uses. Even in languages which contain the feature, it is not always applicable to the same verbs and uses (although a common subset can be generally extracted, as outlined below). For example, the Spanish reflexive construct "se hundió el barco" ("the boat sank") has no reflexive equivalent in some Slavic languages (which use an intransitive equivalent of sink), though for example Czech and Slovak do use a reflexive verb: "loď se potopila"/"loď sa potopila". Reflexive verbs can have a variety of uses and meanings, which often escape consistent classification. Some language-common identified uses are outlined below. For example, Davies et al. identify 12 uses for Spanish reflexive constructions, while Vinogradov divides Russian reflexive verbs into as many as 16 groups.

Martin Haspelmath also has a useful distinction between the reflexive types mentioned below, which he calls introverted reflexives, and so called extroverted reflexives, which are used for verbs that are usually not reflexive, like hate oneself, love oneself, hear oneself, and kill oneself. Some Indo-European languages have a different reflexive morpheme for extroverted reflexives. For example, see how the Russian ненавидеть себя (nenavidet' sebja) "to hate oneself", which uses a reflexive pronoun, compares to мыться (myt'-sja) "to wash (oneself)", which uses a reflexive suffix (Russian can also say мыть себя (myt' sebja), with a reflexive pronoun, but only when the pronoun needs to be stressed for emphasis or contrast). Or Dutch haat zichzelf "hates herself", versus wast zich "washes (herself)". The distinction exists similarly in English, where introverted reflexive verbs usually have no reflexive pronoun, unlike extroverted. In ancient Greek, the introverted reflexive was expressed using the middle voice rather than a pronoun. Similarly, in modern Greek, it is expressed using the middle usage of the passive voice. On the other hand, the extroverted reflexive was a true reflexive in ancient Greek and modern Greek. Similarly Claire Moyse-Faurie distinguishes between middle and reflexive in Oceanic languages in her on-line articles about reflexives in Oceanic languages.

Properly reflexive

The "true" (literal) reflexive denotes that the agent is simultaneously the patient. The verb is typically transitive and can be used in non-reflexive meaning as well.

Spanish	Pedro se lava.	Pedro lava al gato.
Italian	Pietro si lava.	Pietro lava il gatto.

Danish	Peter vasker sig.	Peter vasker katten.
Lithuanian	Petras prausiasi.	Petras prausia katę.
	Petras prausia save.
English	Peter washes himself.	Peter washes the cat.

Reciprocal

See also: Reciprocal pronoun

"Reciprocal" reflexive denotes that the agents perform the mutual actions among themselves. In most cases, the transitive verbs are also used.

Language	Examples	Compare
French	Marie et Pierre s'embrassent	Marie embrasse Pierre
Spanish	María y Pedro se besan.	María besa a Pedro.
Italian	Maria e Pietro si baciano.	Maria bacia Pietro.
Serbo-Croatian	Marija i Petar se ljube.	Marija ljubi Petra.
Polish	Maria i Piotr się całują.	Maria całuje Piotra.
Russian	Мария и Пётр целуются. Mariya i Pyotr tseluyutsya.	Мария целуeт Петрa. Mariya tseluyet Petra.
Danish	Maria og Peter kysser hinanden.	Maria kysser Peter.
Lithuanian	Marija ir Petras bučiuojasi.	Marija bučiuoja Petrą.
English	Мary and Peter kiss [each other].	Mary kisses Peter.

In modern Scandinavian languages, the passive (or more properly mediopassive) voice is used for medial, especially reciprocal, constructions. Some examples from Danish are

Maria og Peter skændes; "Mary and Peter are bickering", lit. "Mary and Peter are scolded by each other."

Maria og Peter blev forlovet; "Mary and Peter got engaged [to each other]."

(The hypothetical form **kysses (kiss each other) is not often—if ever—seen in Danish; however it'll probably be understood by most native speakers, indicating that the mediopassive voice is still at the very least potentially productive in Danish. An expression like "de kysses uafladeligt" (they kiss each other all the time) could very well be used for humorous purposes.)

Autocausative

See also: Autocausative verb

"Autocausative" reflexive denotes that the (usually animate) "referent represented by the subject combines the activity of actor and undergoes a change of state as a patient":

Language	Examples
Spanish	Pedro se ofendió.
Italian	Pietro si offese.
Serbo-Croatian	Petar se uvrijedio.
Polish	Piotr się obraził.
Russian	Пётр обиделся. Pyotr obidelsya.
German	Peter ärgerte sich.
Lithuanian	Petras įsižeidė.
English	Peter became/was offended.

Anticausative

See also: Anticausative verb

"Anticausative" reflexive denotes that the (usually inanimate) subject of the verb undergoes an action or change of state whose agent is unclear or nonexistent.

Language	Examples
Spanish	La puerta se abrió.
Italian	La porta si aprì.
Serbo-Croatian	Vrata su se otvorila.
Polish	Drzwi się otworzyły.
Russian	Дверь открылась. Dver' otkrylas'.
German	Die Tür öffnete sich.
Lithuanian	Durys atsidarė.
English	The door (was, got) opened.

Intransitive or Impersonal

See also: Impersonal passive voice and Mediopassive voice

"Intransitive" forma (also known as "impersonal reflexive" or "mediopassive") take the intransitive verbs with omitted agent. In Slavic languages, practically "the only condition is that they can be construed as having a human agent. The applied human agent can be generic, or loosely specified collective or individual." The grammatical subject is either omitted (in pro-drop languages) or dummy pronoun (otherwise). Thus, those verbs are defective, as they have only the 3rd person singular (masculine or neutrum, depending on language) form.

Language	Examples
Spanish	Aquí se trabaja bien.	Se dice que...
Italian	Qui si lavora bene.	Si dice che...
Serbo-Croatian	Tu se radi dobro.	Smatra se da...
Polish	Tu pracuje się dobrze.	Uważa się, że...
Russian	Здесь хорошо работается. Zdes' khorosho rabotayetsya.	Думается, что... Dumayetsya, chto...
English	[People] work well here.	It is considered that...

In many cases, there is a semantic overlap between impersonal/anticausative/autocausative constructs and the passive voice (also present in all Romance and Slavic languages). On one hand, impersonal reflexive constructs have a wider scope of application, as they are not limited to transitive verbs like the canonical passive voice. On the other hand, those constructs can have slight semantic difference or markedness.

Inherent

"Inherent" or "pronominal" (inherently or essentially) reflexive verbs lack the corresponding non-reflexive from which they can be synchronically derived. In other words, se is an inherent part of an unergative reflexive or reciprocal verb with no meaning of its own, and an obligatory part of the verb's lexical entry":

Language	Examples
Spanish	Pedro se arrepintió.	Pedro se ríe	María y Pedro se separaron.	Pedro se queja.
Italian	Pietro si pentì.		Maria e Pietro si separarono.	Pietro si lamenta.
Serbo-Croatian	Petar se pokajao.	Petar se smije.	Marija i Petar su se rastali.	Petar se žali.
Polish	Piotr się pokajał.	Piotr się śmieje.	Maria i Piotr się rozstali.	Piotr żali się.
Russian	Пётр раскаялся. Pyotr raskayalsya.	Пётр cмеётся. Pyotr smeyotsya.	Мария и Пётр расстались. Mariya i Pyotr rasstalis'.	Пётр жалуeтся. Pyotr zhaluyetsya.
Lithuanian	Petras atsiprašė.	Petras juokiasi.	Marija ir Petras išsiskyrė.	Petras skundžiasi.
English	Peter repented.	Peter laughs.	Mary and Peter parted.	Peter complains.

Hebrew

In Hebrew reflexive verbs are in binyan הִתְפַּעֵל. A clause whose predicate is a reflexive verb may never have an object but may have other modifiers. e.g.

• האיש התפטר מעבודתו - the man resigned from his job
• האיש התמכר לסמים - the man got addicted to drugs
• האיש התקלח בבוקר - the man 'showered himself', i.e., took a shower in the morning
• האישה הסתפרה אצל אבי - the woman took a haircut/had her hair done at Avi's
