THE GIST
The idea behind these word parts
Related roots may change spelling. Produce, production, and productive belong to one family even though duce becomes duct.
Go deeper · how the parts work in context
Produce means make or bring about. Production names the process; productive describes something that produces useful results. The historical lead clue in duc/duct connects the family, but the complete words have more specific meanings.
pro + duct + ive → productive
Their productive meeting ended with an agreed plan.
Productive describes something that produces useful results.
Word parts suggest a meaning; the sentence helps confirm it. If the clues are not enough, check a dictionary.
EXPLORE THE WORD PARTS
Meaning, connections, and practice
Choose a word part. Read its gist, explore its map and matrix, then answer its three checks. Open the extra explanation whenever you need it.
How to use a matrix
Leading part + base + ending → word. Choose cells from left to right. Only paths that make one of the listed words are enabled. ∅ means no part is added.
The center can be a root or a whole word. Some cells contain combining forms or grouped endings. Related bases can change spelling, as in scribe/script or mit/miss; follow the spelling notes.
Keep a word for comparison, then select another word to see which parts and meanings changed.

DECODE · FOLLOW THE CLUES
Use the clue without overtrusting it
A word part gives you a strong clue—not always a complete definition.
Spot the part.Underline the exact letters you recognize.
Recall the clue.Say the meaning you learned for that part.
Test the whole word.Combine the clue with the other parts and the sentence.
Decode aqueduct
Spot aqueduct. The root duc/duct carries the clue lead. Here, it helps you understand: a structure that leads water.
Decode manufacture
Spot manufacture. The root fac/fact/fic/fect carries the clue do or make. Here, it helps you understand: make goods.
Decode retain
Spot retain. The root ten/tain/tin carries the clue hold. Here, it helps you understand: hold back or keep.
Compare the meanings, then test which form fits the sentence.
flexible
able to bend or adapt
inflexible
not willing or able to bend or adapt
Explain the difference
Flex keeps bend. In- means not here. The ending -ible stays the same.
A common mistake—and how to avoid it
Root families can change spelling: produce → production, retain → retention. Learn the related forms together; do not invent a rule that every root keeps identical letters.
