Types of Anaphora
Anaphora is what happens when an expression in a sentence or text gets its meaning by referring back to something mentioned earlier. Without anaphora, you'd have to repeat full noun phrases and verb phrases constantly, making language awkward and redundant. This topic covers three main types: pronominal, VP, and discourse anaphora.
Interpreting anaphora depends on both linguistic context (grammar, sentence structure) and extralinguistic context (world knowledge, speaker intentions). When anaphoric expressions are ambiguous, you resolve them by weighing factors like gender, number, semantic fit, and pragmatic reasoning.
Types of Anaphora
Pronominal anaphora
Pronominal anaphora is the most familiar type. A pronoun refers back to a previously mentioned noun phrase, called its antecedent. The pronoun inherits its reference from that antecedent rather than introducing a new referent.
Common pronoun categories involved:
- Personal pronouns: he, she, it, they
- Possessive pronouns: his, her, its, their
- Reflexive pronouns: himself, herself, itself, themselves
For example: "Sarah finished her exam early. She looked relieved." Here, she is the anaphoric expression and Sarah is the antecedent. The pronoun agrees with its antecedent in gender and number.
VP (Verb Phrase) anaphora
VP anaphora occurs when an entire verb phrase is "replaced" by an auxiliary verb or a pro-form, referring back to a previously mentioned action. Instead of repeating the full verb phrase, English uses forms like do, does, did, or expressions like do so, do it, do that.
-
"John went to the store, and Mary did too." Here, did stands in for went to the store. The full VP is recoverable from the prior clause.
-
"The professor asked us to revise our essays, and most students did so before the deadline." Did so = revised their essays.
The key distinction from pronominal anaphora is that VP anaphora replaces a predicate (an action or event), not a referring expression like a noun phrase.
Discourse anaphora
Discourse anaphora refers back to something larger than a single noun phrase or verb phrase. The antecedent can be an entire proposition, a clause, a sentence, or even a stretch of several sentences. Demonstrative pronouns (this, that) and descriptive noun phrases (the idea, the proposal, the latter) are typical markers.
- "John argued that the company should invest more in research and development. This idea was met with skepticism from the board members." This idea picks up the entire proposition that the company should invest more in R&D.
Discourse anaphora is especially important in written and academic language, where complex ideas need to be referred to compactly without restating them in full.
Anaphora in Textual Coherence
Anaphora serves two related functions in text. First, it creates cohesion by establishing explicit links between different parts of a text, letting writers and speakers avoid clunky repetition. Second, it supports coherence by keeping the reader or listener oriented toward the main topics and ensuring that ideas flow logically from one sentence to the next.
Without anaphora, a passage like "The mayor proposed a new policy. The policy would reduce emissions. The policy was controversial." would feel stilted. Anaphora lets you write: "The mayor proposed a new policy. It would reduce emissions, but it was controversial."
Context for Anaphoric Interpretation
Linguistic context
The surrounding words, phrases, and sentence structure help you identify an anaphoric expression's antecedent. Syntactic rules constrain which noun phrases a pronoun can refer to. For instance, in "She said that Mary was tired," standard binding principles make it unlikely that she and Mary are the same person (though context can sometimes override this).
Extralinguistic context
World knowledge, shared experiences, and cultural background also shape interpretation. If someone says "The surgeon told the nurse that he needed a break," your assumptions about who is more likely to need a break, or about the specific situation, can influence whether you resolve he as the surgeon or the nurse. Pragmatic factors like the speaker's intentions and the goals of the conversation contribute here as well.
Resolving Anaphoric Ambiguities
When an anaphoric expression has more than one possible antecedent, you need a strategy for choosing the right one. Here's how resolution typically works:
- Check grammatical agreement. Does the pronoun match potential antecedents in gender and number? This often narrows the field quickly.
- Assess semantic compatibility. Does the antecedent make sense given what the sentence says? In "The lock was rusty, so John replaced it," it refers to the lock because replacing rustiness doesn't make sense.
- Consider syntactic position. Subjects and recently mentioned noun phrases tend to be more accessible antecedents than deeply embedded ones.
- Apply pragmatic reasoning and world knowledge. When grammar and semantics don't resolve the ambiguity, context and plausibility step in.
A classic example: "John told Bill that he should leave." The pronoun he could refer to John or Bill. Grammar alone doesn't settle it. You'd need the surrounding discourse or situational context to determine the intended referent.
