Once Upon a Word: A Word-Origin Dictionary for Kids - Jess Zafarris 2020
Roots & Branches
Word jungle
In order to begin our journey as word detectives, we need to break down words into smaller parts. Many words are made up of roots, prefixes, and suffixes that you can put together like building blocks to make new words. A root is the most basic form of a word. Prefixes and suffixes are word parts you can add to the root to help define it. The prefix comes before a root, and the suffix comes after it.
Some roots are whole words, like labor, meaning “work,” while others are word parts, like -lumin- meaning “light.” When prefixes and suffixes are added to roots, longer words are built. Look at what happens when we add prefixes and suffixes to lumin- and labor.
Word |
Prefix |
Root |
Suffix |
Meaning |
ILLUMINATION |
il- “in, on” |
lumin “light” |
-ation, -tion “state of being” |
the state of being lit up, the state of having light on something |
COLLABORATE |
co- “together” |
labor “work” |
-ate “become, do” |
to do work together |
Here’s a secret that not everyone realizes: Prefixes and suffixes are magic. By adding a prefix or suffix to a root word, you can make it change direction, change color, grow, shrink, or even turn into its own opposite! For example, let’s take the root word appear. If you add the prefix dis- to it, you get “disappear.” See? We made “appear” disappear just by adding a prefix—just like magic.
The charts below show common roots, their Greek and Latin origins, their meanings, and examples. They are followed by some common prefixes and suffixes.
See how many words you can make by adding prefixes and suffixes to the roots!
LITERALLY, DEFINED
In this book, you’ll see definitions that include “literal” meanings of words. The definition of a word is the way we use it in a sentence. But when we’re studying etymology, we discover the literal meanings of words, or what their origins and pieces meant in older languages.
For example, when we use the word “muscle,” we’re talking about the body parts that make us strong. It comes from the Latin word for muscle, musculus, which is also translated as “little mouse” and comes from the Latin base word mus, meaning “mouse.” Muscles are named after mice because it was thought that flexing your muscles made it look like mice were crawling under your skin. Even though musculus also meant “muscle” in Latin, “little mouse” is the literal meaning of the word.

THE LONELIEST WORDS
A base word that doesn’t exist (or is very rarely used) without a prefix or suffix is called an unpaired word.
For example, we say we are overwhelmed or underwhelmed, but it’s rare to hear someone say they’re just “whelmed”. Someone can be reckless, but what does it mean to have “reck?” You can debunk a rumor, but was the rumor “bunked” in the first place?
