This reading introduces three key pragmatic phenomena—presuppositions, entailments, and implicatures—and explores their roles in communication. Designed for MA students in applied linguistics, this resource provides definitions, examples, and applications to deepen your understanding of how meaning is conveyed beyond the literal content of utterances. These concepts are essential for analyzing discourse, understanding intercultural communication, and conducting research in pragmatics, sociolinguistics, and related fields.

1. Presuppositions

Definition

Presuppositions are background assumptions that a speaker takes for granted as true when producing an utterance. These assumptions are triggered by specific linguistic structures (e.g., verbs, definite descriptions) and typically remain true even when the sentence is negated. Presuppositions rely on shared knowledge or context between the speaker and listener.

Characteristics

• Triggered by linguistic elements: Certain words or structures, known as presupposition triggers, signal these assumptions.
• Resistant to negation: The presupposition often holds in both positive and negative forms of a sentence.
• Context-dependent: Presuppositions may fail if the assumed information is not shared or accepted.

Examples

1. Factive verb: "She regretted missing the lecture."
   • Presupposition: She missed the lecture.
   • Negation: "She didn’t regret missing the lecture." (Still presupposes she missed the lecture.)
2. Definite description: "The CEO of the company resigned."
   • Presupposition: There is a CEO of the company.
3. Temporal clause: "After he won the award, he gave a speech."
   • Presupposition: He won the award.

Applications in Applied Linguistics

• Discourse Analysis: Presuppositions can subtly shape audience perceptions in media or political discourse (e.g., "When will the government fix the economy?" presupposes the economy needs fixing).
• Intercultural Communication: Misaligned presuppositions can lead to misunderstandings in cross-cultural settings if speakers assume different background knowledge.
• Language Teaching: Teaching learners to recognize presuppositions improves their pragmatic competence and ability to infer implied meanings.

2. Entailments

Definition

Entailments are logical consequences of a sentence that must be true if the sentence itself is true. Unlike presuppositions, entailments are directly tied to the semantic content of the sentence and do not survive negation. Entailments are a matter of strict logical implication, not pragmatic inference.

Characteristics

• Logical necessity: If sentence A entails sentence B, then if A is true, B must also be true.
• Sensitive to negation: Negating the original sentence cancels the entailment.
• Context-independent: Entailments depend on the sentence’s meaning, not the conversational context.

Examples

1. Sentence: "Maria adopted two cats."
   • Entailment: Maria adopted at least one cat.
   • Negation: "Maria didn’t adopt two cats." (Does not entail that she adopted at least one cat; she may have adopted none or more than two.)
2. Sentence: "The team won the championship."
   • Entailment: The team participated in the championship.
3. Sentence: "He is a bachelor."
   • Entailment: He is an unmarried man.

Applications in Applied Linguistics

• Semantics and Logic: Entailments are crucial for understanding how meaning is structured in language and for building precise models in computational linguistics.
• Legal Discourse: In legal texts, entailments ensure clarity in contracts or statutes, where logical implications must be unambiguous.
• Language Processing: Recognizing entailments aids in natural language processing tasks, such as question answering or text summarization, where systems must infer logical consequences.

3. Implicatures

Definition

Implicatures are meanings that are implied by a speaker but not explicitly stated, arising from the conversational context and principles of cooperation (e.g., Grice’s maxims). Unlike presuppositions and entailments, implicatures are cancellable—speakers can deny them without contradicting themselves—and are highly context-dependent.

Characteristics

• Conversational vs. Conventional: Conversational implicatures arise from context and Grice’s maxims (quantity, quality, relevance, manner), while conventional implicatures are tied to specific words (e.g., "but" implies contrast).
• Cancellable: Implicatures can be explicitly denied without logical contradiction.
• Context-sensitive: They depend on the situation, shared knowledge, and speaker intent.

Examples

1. Conversational Implicature:
   • Utterance: "I have two cats."
   • Implicature: I have exactly two cats (based on the maxim of quantity, assuming the speaker is providing all relevant information).
   • Cancellation: "I have two cats—actually, I have three." (No contradiction.)
2. Conventional Implicature:
   • Utterance: "She’s talented but shy."
   • Implicature: There is a contrast between being talented and shy (triggered by "but").
3. Scalar Implicature:
   • Utterance: "Some students passed the exam."
   • Implicature: Not all students passed (based on the assumption that the speaker would say "all" if it were true).

Applications in Applied Linguistics

• Pragmatics: Implicatures are central to understanding how speakers convey meaning indirectly, such as in politeness strategies or humor.
• Cross-Cultural Communication: Different cultures may interpret implicatures differently, leading to potential miscommunication (e.g., indirect refusals may be missed).
• Language Acquisition: Second-language learners often struggle with implicatures, as they require cultural and contextual knowledge beyond grammar.

Comparing Presuppositions, Entailments, and Implicatures

Practical Applications in Applied Linguistics

1. Discourse Analysis: These phenomena reveal how meaning is constructed in texts. For example, presuppositions in news headlines can frame issues (e.g., "How will the government address the crisis?" presupposes a crisis exists), while implicatures in interviews may signal bias or intent.
2. Intercultural Communication: Misunderstandings often arise when presuppositions or implicatures are not shared across cultures. For instance, a speaker’s implicature of politeness (e.g., "I’m not sure I can make it") may be taken literally by a listener from a different cultural background.
3. Language Teaching and Learning: Teaching students to recognize presuppositions, entailments, and implicatures enhances their pragmatic competence, enabling them to navigate implied meanings in real-world communication.
4. Media and Power Dynamics: Presuppositions and implicatures are tools for persuasion or manipulation in advertising, politics, and propaganda. Analyzing these can uncover hidden agendas or ideological framing.
5. Computational Linguistics: Understanding these phenomena is vital for developing AI systems that process natural language, such as chatbots or translation tools, which must infer implied meanings accurately.

Reflection Questions

1. Identify a presupposition, entailment, and implicature in a recent conversation or text you encountered. How did each affect the communication?
2. How might presuppositions or implicatures create challenges in your research area (e.g., corpus linguistics, sociolinguistics, translation studies)?
3. Consider a cross-cultural scenario. How could differing interpretations of implicatures lead to miscommunication, and how might this be mitigated?
