Main summary
Key takeaways
Main ideas and concepts
- Unit 6 is the final unit of the course and is for self-study only (no assignment).
- The unit focuses on non-literal meaning, specifically speaker meaning / implied meaning.
- It introduces two main topics for the overall section:
- Conversational implicature (the focus of this video)
- Cooperative principles (covered in later videos)
Conversational implicature (speaker meaning)
Conversational implicature is a type of meaning where the listener derives an implied conclusion about what the speaker means.
- The implied meaning is not explicitly stated in the utterance.
- It is understood using conversational rules.
Contrast with entailment (literal/sentence meaning)
The video distinguishes two kinds of meaning:
1) Entailment (called “internment” in the subtitles)
- Entailment relates to the sentence’s literal meaning.
- It is a logical conclusion that follows from what is literally said.
- It is independent of speaker intention.
Example
- “Mary bought three dresses.”
- Implicit literal conclusion: “Mary bought some garments.”
- Because “dress” is a type of “garment.”
Mini-example
- “Food is …” leads to a logical subset/superset relationship, illustrating entailment via logical structure.
2) Conversational implicature (speaker meaning)
- Implicature relates to the speaker’s intended meaning.
- It is a conclusion based on the rules/expectations of conversation (what makes sense socially and interactively).
Example
- John: “Did Mary buy three books for her study?”
- Jane: “Many more three dresses.”
The listener may infer (implicature) that:
- Mary didn’t buy any books, because Jane’s answer seems to sidestep John’s question and instead mentions dresses.
Key point: Even if an utterance seems not to directly align with the question/topic, listeners use conversational norms to infer what is meant.
Conversational-rule mechanism (how implicature is derived)
The video explains a general conversational dynamic:
- Speakers aim to help listeners understand what they mean (even indirectly).
- Listeners use conversational reasoning to decode the implied meaning, following conversational rules.
Self-study exercises mentioned (instruction-style breakdown)
The subtitles reference exercises to practice the concepts:
Review exercise on entailment
- Exercise (page 314): richest/relevant exercise to review the basic concept of entailment.
- Instruction: Do it by yourself.
Practice exercise on entailment vs. implicature
- Exercise (page 316): focuses on entailment vs. implicature.
- Instruction: Look at the verbs used in each sentence and answer whether certain conclusions are valid.
Guidance for specific numbered items
-
“Conclude” question type
- Prompt: If Katie’s father didn’t give her any supper, is it reasonable to conclude Katie got no supper?
- Answer depends on conversational/background conditions:
- Yes if nobody else gave her supper.
- Not necessarily if another person (e.g., her mother/others) gave it.
-
Use “conclude”
- Emphasis: evaluate whether the conclusion is warranted.
-
Focus on the verb
- Instruction (as referenced): identify what the verb signals about meaning—whether it reflects logical structure vs. implication.
-
“Infer” / inference-based reasoning
- Evaluate meanings that come from inference rather than direct literal entailment.
-
Use “inference”
- Instruction: determine whether the intended meaning comes from inferential reasoning (implicature) versus strict logical consequence (entailment).
- Instruction on questions: If learners have questions, they can ask in class to discuss.
Speakers / sources featured
- None explicitly named as speakers.
- No identifiable real-world source voices are featured in the subtitles.
- The only “source” referenced is:
- A textbook (subtitles reference page 314 and page 316).
