THE GIST

The idea behind these word parts

Time and order words connect events. Synchronize means make things operate at the same time or rate.

Go deeper · how the parts work in context

Synchronize joins syn- together, chron time, and -ize to form a verb. This class list includes roots and combining forms as well as prefixes: tempor and chron are time roots.

syn + chron + ize → synchronize

The team will synchronize its clocks before the experiment.

Synchronize means make things occur or operate at the same time or rate.

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.

01

temp-/tempor-

time

root / combining form

The gist: temporary means lasting for a limited time. The clue temp-/tempor- connects it to time.

Why it works · examples & details

The shared clue is the meaning of the leading part: time. Compare temporary (lasting for a limited time) with contemporary (belonging to the same time). The complete word’s definition is more specific than the word-part clue.

tempor + ary → temporary
Lasting for a limited time. It works as a adjective in this example.

Meaning & spelling: The workbook groups this with prefixes, but temp-/tempor- usually behaves as a root or combining form.

The map and matrix show established words. Matching letters alone do not prove a meaningful relationship.

  • con + tempor + aryadjective

neo-

new

The gist: neonatal means relating to a newborn. The clue neo- connects it to new.

Why it works · examples & details

The shared clue is the meaning of the leading part: new. Compare neonatal (relating to a newborn) with neologism (a newly created word). The complete word’s definition is more specific than the word-part clue.

neo + natal → neonatal

root / combining form

The gist: equidistant means equally distant. The clue equ-/equi- connects it to equal.

Why it works · examples & details

The shared clue is the meaning of the leading part: equal. Compare equidistant (equally distant) with equilateral (having equal sides). The complete word’s definition is more specific than the word-part clue.

equ + al → equal
The same in amount or value. It works as a adjective in this example.

Meaning & spelling: Equ-/equi- is usually treated as a root or combining form.

sync/synch family

at the same time

word-family bridge

The gist: synchronous means happening at the same time. The clue sync/synch family connects it to at the same time.

Why it works · examples & details

The shared clue is the meaning of the leading part: at the same time. Compare synchronous (happening at the same time) with synchronize (make events happen at the same time). The complete word’s definition is more specific than the word-part clue.

synchron + ous → synchronous
Happening at the same time. It works as a adjective in this example.

Meaning & spelling: Sync/synch spans an older boundary: syn- means “together” and chron- means “time.” Learn it as a word-family clue, not a productive prefix.

follow or following

root / combining form

The gist: sequence means things following in order. The clue seq-/sequ- connects it to follow or following.

Why it works · examples & details

The shared clue is the meaning of the leading part: follow or following. Compare sequence (things following in order) with sequel (a story that follows another). The complete word’s definition is more specific than the word-part clue.

sequ + ence → sequence
An order in which things follow each other. It works as a noun in this example.

Why it works · examples & details

The shared clue is the meaning of the leading part: old or ancient. Compare paleontology (the study of ancient life) with Paleolithic (related to the ancient Stone Age). The complete word’s definition is more specific than the word-part clue.

Why it works · examples & details

The shared clue is the meaning of the leading part: before. Compare forecast (predict beforehand) with foreword (words placed before a book’s main text). The complete word’s definition is more specific than the word-part clue.

fore + cast → forecast
A statement about what is expected to happen. It works as a noun in this example.

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 contemporary

Spot contemporary. The leading word part temp-/tempor- carries the clue time. Here, it helps you understand: belonging to the same time.

Decode neologism

Spot neologism. The leading word part neo- carries the clue new. Here, it helps you understand: a newly created word.

Decode equilateral

Spot equilateral. The leading word part equ-/equi- carries the clue equal. Here, it helps you understand: having equal sides.

MEANING & GRAMMAR

What changes when the word changes?

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

temporary

lasting a limited time

contemporary

belonging to the same time

Explain the difference

Tempor keeps time. Con- contributes together in contemporary. The two complete words do not mean the same thing.

Which adverb completes the sentence? “The closure is temporary. The bridge is ___ closed.”

A common mistake—and how to avoid it

This class list includes roots and combining forms as well as prefixes. Tempor is a time root, and chron is the time root in synchronize. Their location alone does not make them prefixes.
