Goal
Use prefixes to produce nuanced, concise, high-band lexical control.
C1 Standard
At C1, word formation should support argument density and register accuracy. Your choice of formed words should sharpen meaning, not decorate weak ideas.
Advanced Formation Moves
- un- + fair -> unfair
- re- + write -> rewrite
- mis- + understand -> misunderstand
- dis- + agree -> disagree
Advanced control examples:
- regulate -> deregulate (policy shift)
- informed -> misinformed (accuracy/ethics)
- productive -> counterproductive (evaluation)
Argument Upgrade Example
- Basic: This policy is bad for poor families.
- C1: This policy is counterproductive because it disproportionately penalizes financially vulnerable households.
Practice
Exercise 1: Precision Selection
Choose the most precise formed word for each context (6 items).
Exercise 2: Compression Rewrite
Rewrite each sentence to reduce word count by 20% using formed words without losing meaning:
- The policy did not work because it produced the opposite result.
- Some media reports gave people wrong information about vaccines.
- The new system made reporting more clear and open.
Exercise 3: C1 Mini-Essay Paragraph
Write 7 sentences on this prompt: Governments should prioritize environmental protection even if economic growth slows. Requirements:
- one qualified claim
- one concession
- one evidence-based example
- at least 10 high-value formed words
Answer Key
Exercise 2 (Possible)
- The policy failed because it was counterproductive.
- Some reports misinformed the public about vaccines.
- The new system improved reporting transparency.
C1 Check
- Do formed words improve precision and register?
- Is each formed word semantically exact?
- Did I avoid inflated, unnecessary nominalization?
