Lesson 6: Building, Breaking & Transforming
Decode • Connect • Apply • Transfer
Use roots as meaning clues, then test them in real context.
Root Discovery Map
Six root families. Twelve target words.
struct = build
constructive - helpful and intended to improve
infrastructure - the basic systems and structures needed for operation
rupt = break
disrupt - to interrupt normal activity
rupture - a break, burst, or serious breach
fract = break
fracture - a crack or break
refractory - stubbornly resistant to control or treatment
form = shape
transform - to change greatly in form or character
conform - to act according to a standard or pattern
fac/fect = make, do
manufacture - to make goods, often on a large scale
defective - having a fault or flaw
mut = change
mutable - capable of change
permutation - a change in arrangement or order
The 5-Step Decode Method
Roots are clues - not complete definitions.
1 Spot
Find the root.
2 Recall
Recall its broad meaning.
3 Combine
Add prefix/suffix clues.
4 Test
Test against context.
5 Confirm
Confirm with a reliable definition.

Models for comparison; other well-supported answers may also be correct.
1. Choose one root from this lesson and explain how its meaning appears in both words in that root family.
Sample response: The root struct means “build.” A strong response explains how that idea appears in both constructive and infrastructure, while noting that the full definitions are not identical.
2. Write an original sentence using one vocabulary word. Include enough context clues for a reader to infer the word's meaning.
Sample response: A student could use disrupt in a complete sentence and include details that clearly suggest “to interrupt normal activity.”

3. Compare two vocabulary words from different root families. Explain one important difference in meaning or usage.
Sample response: Compare fracture with transform. Define each word, identify the roots, and give a short example showing why the words are not interchangeable.
4. Describe a safe method for using roots to predict the meaning of a word you have never seen before.
Sample response: Identify the root, recall its broad meaning, examine any prefix and suffix, and test the prediction against the sentence. Then confirm the meaning with a reliable dictionary or source.
