Definition:
Conversational implicature is inferred meaning that goes beyond the literal content of an utterance — what a speaker communicates without literally saying it. The concept was developed by British philosopher H.P. Grice in his landmark 1975 paper “Logic and Conversation,” as part of his broader account of how speakers communicate more than they literally say through cooperative pragmatic reasoning. A conversational implicature is generated when a listener infers, on the basis of contextual and conversational reasoning (primarily the assumption that the speaker is being cooperative and rational), what the speaker intended to communicate beyond the literal proposition expressed.
Grice’s Example
Consider the exchange:
> A: “Did you finish the report?”
> B: “I’ve been very busy today.”
B’s reply is literally just an assertion about being busy. But A can infer: “B has not finished the report.” This inference — not encoded in B’s words but calculable from the context and the assumption of cooperative communication — is a conversational implicature.
How Implicatures Are Calculated
Grice proposed that listeners infer conversational implicatures by: assuming the speaker is cooperative (following the Cooperative Principle — see Cooperative Principle) and reasoning about what the speaker must have meant given the CP maxims:
- Quantity: Be as informative as needed (no more, no less)
- Quality: Don’t say what you believe to be false; don’t assert what you lack evidence for
- Relation: Be relevant
- Manner: Be clear, orderly, brief, avoid ambiguity
When an utterance appears to violate a maxim, the listener infers that the speaker is flouting it deliberately to implicate something.
Example of Quality flouting (irony):
> (In a torrential downpour) “Lovely weather today.”
The speaker obviously believes the weather is terrible — they appear to violate Quality. The listener infers: the speaker is being ironic; they implicate the opposite.
Example of Quantity flouting:
> A: “How was the party?”
> B: “There was a lot of food.”
B’s response says very little about the party overall. The listener infers: B didn’t enjoy it (otherwise, a fully informative response would have been given).
Types of Implicature
Generalized conversational implicature:
Inferences that arise in most default contexts without special knowledge.
> “I met a woman yesterday” — implicates “not my wife/known person” by default (otherwise more specific identification would have been given — Quantity implicature)
Particularized conversational implicature:
Inferences that depend on specific contextual knowledge.
> “The lecture was fine.” — in context where the listener knows the speaker hates the professor, this implicates “extremely disappointing”
Cancellability
A key property of conversational implicatures: they are cancellable without contradiction.
> “I met a woman yesterday — in fact, it was my wife.”
The Quantity implicature (not my wife) can be cancelled explicitly without logical contradiction. This distinguishes implicatures from conventional meaning (which cannot be cancelled).
Implicature and L2 Pragmatics
Conversational implicature is a critical pragmatic target for L2 learners:
- L2 learners must learn to generate and interpret implicatures without access to the full cultural and pragmatic knowledge native speakers deploy
- Individuals with lower L2 proficiency often miss implicatures — interpreting utterances too literally
- Cross-cultural differences in implicature conventions mean that L2 learners may misread cooperative communication assumptions
Japanese-specific: Japanese communication is often described as relying heavily on implicit communication and contextual inference (高コンテクスト文化, high-context culture). Understanding indirect no responses — where a Japanese speaker implicates refusal without explicitly saying so — is pragmatically essential.
History
The concept of conversational implicature was developed by the philosopher H.P. Grice in his William James Lectures at Harvard in 1967, which were widely circulated as unpublished manuscripts before being formally published in Logic and Conversation (1975). Grice’s framework distinguished between what is said (the literal, coded meaning) and what is implicated (the meaning conveyed beyond the literal). He proposed the Cooperative Principle and four maxims (Quantity, Quality, Relation, Manner) as the basis for implicature generation. Grice’s work became foundational for pragmatics, semantics, and philosophy of language, influencing neo-Gricean theories (Horn, Levinson), Relevance Theory (Sperber and Wilson), and sociolinguistic politeness theory (Brown and Levinson). Its implications for L2 pragmatics and cross-cultural communication were developed extensively from the 1980s onward.
Common Misconceptions
“Conversational implicature is just being indirect.” Indirectness and implicature overlap but are distinct. Implicature refers specifically to inferences generated by applying the Cooperative Principle to utterances — what a hearer concludes the speaker meant beyond the literal content, given the assumption that the speaker is being cooperative. Not all indirect communication generates Gricean implicature; some indirectness is conventional (encoded in idioms or politeness routines) rather than inferential.
“Implicatures are always intentional on the speaker’s part.” Grice distinguished between speaker meaning (what the speaker intends) and hearer inferences. While implicature involves hearer reasoning about speaker intention, speakers may not consciously intend the inferences hearers draw, and cultural context heavily shapes which implicatures are routinely generated. Cross-cultural misunderstandings often arise from hearers generating implicatures that speakers did not intend.
Criticisms
Grice’s maxims have been criticized for being descriptive of middle-class Anglo-American conversational norms rather than universal communicative principles. Cross-cultural pragmatics research has documented significant variation in how cooperative principles are interpreted and applied — particularly in the maxims of Quantity (how much information is appropriate) and Relation (what counts as relevant). Relevance Theory (Sperber and Wilson, 1986) proposed a more parsimonious account of pragmatic inference using a single cognitive principle (relevance) rather than Grice’s four maxims, arguing that Grice’s framework is descriptively adequate but theoretically over-complex.
Social Media Sentiment
Conversational implicature is discussed in pragmatics education content, language learning communities, and in popular discussions of “reading between the lines” in communication. Japanese politeness and indirect refusal patterns are frequently discussed in Japanese language learning communities as classic examples of implicature — indirect refusals (ちょっと… chotto…) require pragmatic inferencing that literal interpretation misses entirely. Content about how to interpret indirect communication across cultures uses implicature principles without the technical term, and misunderstood implicatures are a rich source of cross-cultural miscommunication anecdotes.

Practical Application
Understanding conversational implicature is essential for L2 pragmatic competence — particularly in languages with strong indirect communication norms like Japanese, Korean, and Chinese. Learners need to develop sensitivity to flouted maxims (deliberate violations that generate implicature), indirect refusals, and culturally specific implicature patterns. Extensive authentic input — listening to native speakers in natural conversation, watching unscripted L2 media — exposes learners to implicature in context in ways that textbooks rarely achieve.
