THE GIST
The idea behind these word parts
Adjectives can describe a relationship or tendency. Contradictory describes statements or actions that conflict.
Go deeper · how the parts work in context
Contra- contributes against and dict connects to saying. The -ory ending forms an adjective here. Endings such as -ent can do more than one job: compare “dependent on trade” with “a dependent.”
contra + dict + ory → contradictory
The two contradictory accounts gave different dates for the same event.
Contradictory describes claims that conflict.
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.

-ary / -ory
related to or connected with
adjective maker
The gist: planetary means related to planets. The clue -ary / -ory connects it to related to or connected with.
Why it works · examples & details
The shared clue is the meaning or word job added by the ending: related to or connected with. Compare planetary (related to planets) with sensory (related to the senses). The complete word’s definition is more specific than the word-part clue.
sens + ory → sensory Connected to seeing, hearing, touch, taste, or smell. It works as a adjective in this example.
In a sentence: Sensory details about cold and ice make the Choctaw journey more concrete.
The map and matrix show established words. Matching letters alone do not prove a meaningful relationship.

-ent / -ant
being, having, or showing a tendency
adjective maker
The gist: dependent means being in a state of depending. The clue -ent / -ant connects it to being, having, or showing a tendency.
Why it works · examples & details

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 sensory
Spot sensory. The suffix -ary / -ory carries the clue related to or connected with. Here, it helps you understand: related to the senses.
Decode observant
Spot observant. The suffix -ent / -ant carries the clue being, having, or showing a tendency. Here, it helps you understand: showing a tendency to notice carefully.
Decode historical
Spot historical. The suffix -ic / -ical carries the clue related to or characterized by. Here, it helps you understand: related to history.
Compare the meanings, then test which form fits the sentence.
depend
rely on: a verb
dependent
relying on something: an adjective in “dependent on trade”
Explain the difference
The ending -ent helps describe the condition here. Dependent can also be a noun for a person supported by another; context matters.
A common mistake—and how to avoid it
Historic often means important in history; historical means related to history. They share a family but are not interchangeable in every sentence.
REVIEW · BRING ROOTS BACK
Keep these roots working
Before opening each matrix, recall the root’s meaning. Build the review words, then explain the whole word. These core roots return in later lessons with new word forms.
