Supplied materials

  • Paper and pencil, or a browser text area. All named people/events/records are fictional learning inputs.
  • Worked case: Excerpt A: Jo chose the cautious route because the bridge was untested. The decision appears before its reason. Excerpt B: Context: Jo spends carefully to avoid waste. The description is thrifty. Excerpt C: Jo will decide; the decision is Jo’s. Analyze decide becoming decision. Excerpt D: Supplied entry: orbit comes from Latin orbita, meaning course or track.

Derivational patterns can change word class: decide to decision, science to scientific, careful to carefully. Inflection can change time or number without the same class shift.

Compare the supplied original and derived forms in their stated roles. Explain how the ending changes their sentence job.

Original worked input: Original excerpt C: Jo will decide; the decision is Jo’s. Analyze decide becoming decision. The task is to use a word-family change. The answer is “verb to noun”. Evidence: Jo will decide; the decision is Jo’s. Analyze decide becoming decision. Reasoning: verb to noun is supported because a verb naming an action becomes a noun naming its result. Decided remains a verb form here.

  3. Check the worked solution: verb to noun. Evidence: Jo will decide; the decision is Jo’s. Analyze decide becoming decision. Reasoning: verb to noun is supported because a verb naming an action becomes a noun naming its result. Decided remains a verb form here.
