THE GIST

The idea behind these word parts

A root carries a core idea into a group of related words. In transport, port contributes carry and trans- contributes across.

Go deeper · how the parts work in context

Transport means move people or goods from one place to another. The root carries a shared meaning; the other parts help specify what kind of carrying is involved. Import and export keep port but change the direction.

trans + port → transport

Railroads transport people and goods between cities.

Here transport is a verb: move people or goods from one place to another.

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.

  1. Spot the part.Underline the exact letters you recognize.
  2. Recall the clue.Say the meaning you learned for that part.
  3. Test the whole word.Combine the clue with the other parts and the sentence.
Decode react

Spot react. The root act carries the clue do. Here, it helps you understand: act in response.

Decode agenda

Spot agenda. The root ag/ig carries the clue drive or do. Here, it helps you understand: things to be done.

Decode uniform

Spot uniform. The root form carries the clue shape. Here, it helps you understand: having one form.

MEANING & GRAMMAR

What changes when the word changes?

Compare the meanings, then test which form fits the sentence.

import

bring goods into a country

export

send goods out of a country

Explain the difference

Port keeps the carry meaning. Im- points inward here; ex- points outward. The direction changes.

Which form completes the sentence? “The workers decided to act together. Their collective ___ changed the workplace.”

A common mistake—and how to avoid it

A shared string of letters is only a clue. The root port means carry in transport; do not treat every word containing p-o-r-t as the same family without checking its meaning.
