Nomenclature and examples

The term ''anaphora'' is actually used in two ways. In a broad sense, it denotes the act of referring. Any time a given expression (e.g. a proform) refers to another contextual entity, anaphora is present. In a second, narrower sense, the term ''anaphora'' denotes the act of referring backwards in a dialog or text, such as referring to the left when an anaphor points to its left toward its antecedent in languages that are written from left to right. Etymologically, ''anaphora'' derives from
Ancient Greek Ancient Greek includes the forms of the Greek language Greek ( el, label=Modern Greek Modern Greek (, , or , ''Kiní Neoellinikí Glóssa''), generally referred to by speakers simply as Greek (, ), refers collectively to the diale ...
ἀναφορά (anaphorá, "a carrying back"), from ἀνά (aná, "up") + φέρω (phérō, "I carry"). In this narrow sense, anaphora stands in contrast to
cataphora In linguistics Linguistics is the science, scientific study of language. It encompasses the analysis of every aspect of language, as well as the methods for studying and modeling them. The traditional areas of linguistic analysis include ph ...
, which sees the act of referring forward in a dialog or text, or pointing to the right in languages that are written from left to right: Ancient Greek καταφορά (kataphorá, "a downward motion"), from κατά (katá, "downwards") + φέρω (phérō, "I carry"). A proform is a cataphor when it points to its right toward its postcedent. Both effects together are called either anaphora (broad sense) or less ambiguously, along with
self-reference Self-reference occurs in natural language, natural or formal languages when a Sentence (linguistics), sentence, idea or Well-formed formula, formula refers to itself. The reference may be expressed either directly—through some intermediate s ...
they comprise the category of endophora. Examples of anaphora (in the narrow sense) and cataphora are given next. Anaphors and cataphors appear in bold, and their antecedents and postcedents are underlined: ::Anaphora (in the narrow sense, species of endophora) ::a. Susan dropped the plate. It shattered loudly. – The pronoun ''it'' is an anaphor; it points to the left toward its antecedent ''the plate''. ::b. The music stopped, and that upset everyone. – The demonstrative pronoun ''that'' is an anaphor; it points to the left toward its antecedent ''The music stopped''. ::c. Fred was angry, and so was I. – The adverb ''so'' is an anaphor; it points to the left toward its antecedent ''angry''. ::d. If Sam buys a new bike, I will do it as well. – The verb phrase ''do it'' is an anaphor; it points to the left toward its antecedent ''buys a new bike''. ::Cataphora (included in the broad sense of anaphora, species of endophora) ::a. Because he was very cold, David put on his coat. – The pronoun ''he'' is a cataphor; it points to the right toward its postcedent ''David''. ::b. His friends have been criticizing Jim for exaggerating. – The possessive adjective ''his'' is a cataphor; it points to the right toward its postcedent ''Jim''. ::c. Although Sam might do so, I shall not buy a new bike. – The verb phrase ''do so'' is a cataphor; it points to the right toward its postcedent ''buy a new bike''. ::d. In their free time, the boys play video games. – The possessive adjective ''their'' is a cataphor; it points to the right toward its postcedent ''the boys''. A further distinction is drawn between endophoric and exophoric reference. Exophoric reference occurs when an expression, an exophor, refers to something that is not directly present in the linguistic context, but is rather present in the situational context. Deictic proforms are stereotypical exophors, e.g. ::Exophora ::a. This garden hose is better than that one. – The demonstrative adjectives ''this'' and ''that'' are exophors; they point to entities in the situational context. ::b. Jerry is standing over there. – The adverb ''there'' is an exophor; it points to a location in the situational context. Exophors cannot be anaphors as they do not substantially refer within the dialog or text, though there is a question of what portions of a conversation or document are accessed by a listener or reader with regard to whether all references to which a term points within that language stream are noticed (i.e., if you hear only a fragment of what someone says using the pronoun ''her'', you might never discover who ''she'' is, though if you heard the rest of what the speaker was saying on the same occasion, you might discover who ''she'' is, either by anaphoric revelation or by exophoric implication because you realize who ''she'' must be according to what else is said about ''her'' even if ''her'' identity is not explicitly mentioned, as in the case of homophoric reference). A listener might, for example, realize through listening to other clauses and sentences that ''she'' is ''a Queen'' because of some of her attributes or actions mentioned. But which queen? Homophoric reference occurs when a generic phrase obtains a specific meaning through knowledge of its context. For example, the referent of the phrase ''the Queen'' (using an emphatic

, a listener would not even know what monarchy or historical period is being discussed, and even after hearing ''her'' name is ''Elizabeth'' does not know, even if an English-UK Queen Elizabeth becomes indicated, if this queen means ''Queen Elizabeth I'' or ''Queen Elizabeth II'' and must await further clues in additional communications. Similarly, in discussing 'The Mayor' (of a city), the Mayor's identity must be understood broadly through the context which the speech references as general 'object' of understanding; is a particular human person meant, a current or future or past office-holder, the office in a strict legal sense, or the office in a general sense which includes activities a mayor might conduct, might even be expected to conduct, while they may not be explicitly defined for this office.

pronoun, such as ''himself'' or ''each other'' in English, and analogous forms in other languages. The use of the term ''anaphor'' in this narrow sense is unique to generative grammar, and in particular, to the traditional binding theory. This theory investigates the syntactic relationship that can or must hold between a given proform and its antecedent (or postcedent). In this respect, anaphors (reflexive and reciprocal pronouns) behave very differently from, for instance, personal pronouns.


Complement anaphora

In some cases, anaphora may refer not to its usual antecedent, but to its
complement A complement is often something that completes something else, or at least adds to it in some useful way. Thus it may be: * Complement (linguistics), a word or phrase having a particular syntactic role ** Subject complement, a word or phrase addi ...
set. In the following example a, the anaphoric pronoun ''they'' refers to the children who are eating the ice-cream. Contrastingly, example b has ''they'' seeming to refer to the children who are not eating ice-cream: ::a. Only a few of the children ate their ice-cream. They ate the strawberry flavor first. – They meaning the children who ate ice-cream ::b. Only a few of the children ate their ice-cream. They threw it around the room instead. – They meaning either the children who did not eat ice-cream or perhaps the children who did not eat ice-cream and some of those who ate ice-cream but did not finish it or who threw around the ice-cream of those who did not eat it, or even all the children, those who ate ice-cream throwing around part of their ice-cream, the ice-cream of others, the same ice-cream which they may have eaten before or after throwing it, or perhaps only some of the children so that they does not mean to be all-inclusive In its narrower definition, an anaphoric pronoun must refer to some noun (phrase) that has already been introduced into the discourse. In complement anaphora cases, however, the anaphor refers to something that is not yet present in the discourse, since the pronoun's referent has not been formerly introduced, including the case of 'everything but' what has been introduced. The set of ice-cream-eating-children in example b is introduced into the discourse, but then the pronoun ''they'' refers to the set of non-ice-cream-eating-children, a set which has not been explicitly mentioned.

considerations attend this phenomenon, which following discourse representation theory since the early 1980s, such as work by Kamp (1981) and Heim (File Change Semantics, 1982), and generalized quantifier theory, such as work by Barwise and Cooper (1981), was studied in a series of psycholinguistic experiments in the early 1990s by Moxey and Sanford (1993) and Sanford et al. (1994). In complement anaphora as in the case of the pronoun in example b, this anaphora refers to some sort of complement set (i.e. only to the set of non-ice-cream-eating-children) or to the maximal set (i.e. to all the children, both ice-cream-eating-children and non-ice-cream-eating-children) or some hybrid or variant set, including potentially one of those noted to the right of example b. The various possible referents in complement anaphora are discussed by Corblin (1996), Kibble (1997), and Nouwen (2003). Resolving complement anaphora is of interest in shedding light on brain access to

Anaphora resolution – centering theory

There are many theories that attempt to prove how anaphors are related and trace back to their antecedents, with centering theory (Grosz, Joshi, and Weinstein 1983) being one of them. Taking the computational theory of mind view of language, centering theory gives a computational analysis of underlying antecedents. In their original theory, Grosz, Joshi, & Weinstein (1983) propose that some discourse entities in utterances are more "central" than others, and this degree of centrality imposes constraints on what can be the antecedent. In the theory, there are different types of centers: forward facing, backwards facing, and preferred.


Forward facing centers

A ranked list of discourse entities in an utterance. The ranking is debated, some focusing on theta relations (Yıldırım et al. 2004) and some providing definitive lists.


Backwards facing center

The highest ranked discourse entity in the previous utterance.


Preferred center

The highest ranked discourse entity in the previous utterance realised in the current utterance.
