Drill 82: Explaining a Concept's Meaning Shift
Explain out loud how a single word's meaning expanded, narrowed, or was reframed across a passage — the spoken mirror of Lesson 82's concept-tracking skill.
Learning Objectives
By the end of this drill, you should be able to:
- Explain a concept's meaning shift live, naming the type of change
- Cite the signal words from memory while speaking, not after
- Sustain a multi-sentence explanation without losing the thread
Introduction
Lesson 82 taught you to track a concept's meaning as it expands, narrows, or gets reframed. This drill asks you to explain that shift out loud, in real time — holding the "before" and "after" meanings in your head at once while you speak, the way you'd have to in an actual conversation about a book or report you just read.
Shadow the Model
The word "risk" starts out broad — any delay counts. But later, the report narrows it: a delay only counts as risk if it also breaks a contract deadline.
Listen to how "narrows" gets slight extra stress — that's the word carrying the whole point of the sentence, and a fluent speaker leans on it.
Your Turn
Your Turn
A report first defines "risk" as "any chance a shipment is delayed." Later it adds: risk only counts if the delay also causes a missed contractual deadline. When the timer starts, explain out loud what happened to the concept — name the type of change and what it now excludes.
Explain the shift now — out loud, no notes
Record Yourself
Explain the concept shift, then record it and compare against the model answer.
Model Answer
Show a model answer
There's no single correct wording, but a strong answer sounds like: "The concept of risk gets narrowed — it starts out meaning any delay, but later the report adds a condition: the delay has to also cause a missed contract deadline. So a harmless delay with no financial consequence doesn't count as risk anymore." What matters is naming the change type (narrowing) and stating the excluded case clearly.

Self-Check
Self-Check
- Did you name the correct type of change (narrowing)?
- Did you state clearly what now falls outside the concept's boundary?
- Did you speak in full sentences without long pauses to plan?
