Implicature

Definition:

Implicature is the aspect of meaning that is communicated by an utterance beyond its literal semantic content — what is implied rather than said. The term was introduced by philosopher H.P. Grice to explain how speakers communicate much more than their words literally mean, and how listeners successfully recover this additional meaning through inference guided by conversational norms.


The Core Idea

When someone asks, “Are you thirsty?” and you reply, “I just had a glass of water,” you are not literally answering the question yes or no. Yet your interlocutor understands that you mean “No, I’m not thirsty.” The information “I just had water” implies you’re not thirsty — this implication is an implicature.

Implicature is pervasive in human communication. Grice estimated that most of what we mean goes well beyond what we literally say. Language would be impossibly slow and tedious if speakers had to state every implied meaning explicitly.

Grice’s Cooperative Principle and Maxims

H.P. Grice (1975) argued that conversation is governed by a general Cooperative Principle: speakers try to make their contributions appropriate to the current purpose of the conversation. From this general principle, he derived four Maxims:

  1. Maxim of Quantity — Say enough; don’t say too much or too little
  2. Maxim of Quality — Be truthful; don’t say what you believe to be false
  3. Maxim of Relation — Be relevant
  4. Maxim of Manner — Be clear; avoid obscurity, ambiguity, and prolixity

Implicatures arise when a maxim appears to be violated:

If I ask “Can you drive?” and you say “I’ve had three beers,” you are (at the surface) violating the Maxim of Relation (not directly answering). But because I assume you’re being cooperative, I infer you mean: “No, I can’t safely drive, because I’ve been drinking.” The implicature rescues apparent irrelevance.

Types of Implicature

Conventional implicature:

Triggered by specific words, independent of context. “Even” in “Even Mike passed the test” conventionally implies that Mike was unlikely to pass. This implication is attached to the word, not derived from context.

Conversational implicature (the most important type):

Derived from the interplay of literal meaning and the assumption that the speaker is being cooperative. These break down further into:

  • Generalized conversational implicature: Occurs in most ordinary contexts without special setup. “Some students failed” implicates “Not all students failed” (because if all had failed, you would have said “all”).
  • Particularized conversational implicature: Occurs only in specific contexts, requiring background knowledge. “Can you tell me the time?” at a dinner party implicates “what time is it now?” (not a genuine question about your ability to tell time) — this is context-dependent.

Scalar Implicature

One of the most studied types, arising from quantity scales. If you say “some,” you implicate “not all.” If you say “warm,” you implicate “not hot.” This is because if the stronger term were true, you would (by the Quantity Maxim) be obligated to use it. Saying a weaker term implicates the stronger is false.

Example:

  • “I’ve met some of the applicants” → implicates “not all of them”
  • “The food was good” → may implicate “not excellent”

Implicature vs. Entailment vs. Presupposition

TermWhat it meansExample
EntailmentLogically follows from the literal meaning“The king of France is bald” entails “France has a king”
PresuppositionAssumed background fact“The king of France is bald” presupposes France has a king
ImplicatureAdditional meaning from cooperative inference“Some students passed” implicates “not all passed”

Implicature and Language Learning

For L2 learners, implicature is both crucial and challenging:

  1. Recognizing implicature requires knowing the C1/pragmatic norms of the target culture, not just the grammar
  2. L2 speakers sometimes miss implicatures — they interpret utterances too literally
  3. L2 speakers sometimes produce unintended implicatures — their more direct L1 style creates implications they didn’t intend in L2

Japanese-specific:

Japanese communication is famous for high-context implicature. Direct refusals are rarely made; instead, a slight pause, chotto… (ちょっと…, “a bit…”), or kangaete okimasu (考えておきます, “I’ll think about it”) implies refusal without explicitly saying “no.” An English speaker who expects direct answers may completely miss the implied “no.” Conversely, a Japanese L2 English speaker may use the same indirect formulas in English, leaving English speakers confused.


History and Key Figures

H.P. Grice (1913–1988): Oxford philosopher who introduced the concept of implicature in his 1967 William James Lectures at Harvard (published as “Logic and Conversation” in 1975). His framework transformed pragmatics by explaining how meaning can exceed literal content without violating principles of rational communication.


History

The concept of conversational implicature was introduced by Paul Grice in his 1967 William James Lectures at Harvard (published as “Logic and Conversation” in 1975). Grice proposed the Cooperative Principle — the assumption that conversational participants are making relevant, truthful, clear, and appropriately informative contributions — and the Conversational Maxims (Quantity, Quality, Relation, Manner) that operationalize it. Implicatures arise when apparent maxim violations trigger the pragmatic inference that additional meaning is being communicated. Grice distinguished conversational implicatures (context-dependent, cancelable) from conventional implicatures (lexically encoded, non-cancelable). Gricean pragmatics became foundational for formal and cognitive pragmatics, generating decades of theoretical development (Relevance Theory, neo-Gricean frameworks) and empirical research.


Common Misconceptions

“Implicatures are the same as presuppositions.” Presuppositions are backgrounded assumptions triggered by specific lexical items or grammatical constructions that survive under negation (“John stopped smoking” presupposes John previously smoked — this is true whether the sentence is affirmed or denied). Implicatures are inferences generated from the cooperative context of an utterance that can be canceled without contradiction (“She’s smart, but not THAT smart — I didn’t mean to imply she was gifted”). Both are implicit meaning, but they have different logical properties and different sources.

“Implicature is just what someone implies.” The Gricean concept of implicature has specific theoretical content: it is derived through the assumption of cooperativity and specific maxims, it is cancelable, and it can be calculated through reasoning about the speaker’s communicative intentions. Not all implicit communication counts as implicature in the technical sense — conventional implicatures, for example, are lexically encoded and non-cancelable, making them different in nature from conversational implicatures.


Criticisms

Gricean pragmatics has been extensively critiqued for the vagueness and overlap between maxims (particularly the relationship between the Quantity maxim and Relevance), and for the degree of interpretive flexibility the framework allows. Sperber and Wilson’s Relevance Theory (1986/1995) argued that Grice’s four maxims could be replaced by a single principle of optimal relevance, offering a simpler and more cognitively grounded account. Cross-cultural pragmatics research has challenged the universality of the Cooperative Principle — arguing that what counts as cooperative, relevant, or appropriately informative varies substantially across cultures, limiting the claims to universality.


Social Media Sentiment

Implicature concepts are discussed in language learning communities mainly in pragmatic competence and intercultural communication contexts — understanding why direct translation of “Can you pass the salt?” is pragmatically correct in English but may sound overly formal or artificial in other languages involves understanding implicature and indirect speech acts. For English learners, understanding understatement and litotes (characteristically British forms of implicature) is a common community discussion. The general insight that what is communicated exceeds what is literally said is widely understood, even if the Gricean technical framework is rarely named explicitly in learner communities.

Practical Application

Recognizing implicatures in Japanese:

  • Chotto muzukashii desu ne (ちょっと難しいですね, “it’s a bit difficult”) → often means “no”
  • Kangaete okimasu (考えておきます, “I’ll think about it”) → polite refusal
  • Sou desu ne… (そうですね…) with hesitation → disagreement or uncertainty, not agreement

Producing appropriate implicatures:

Advanced L2 speakers learn to exploit implicature to be polite. Rather than “No,” say something that implicates you can’t or won’t — this saves face for both parties.
