What is a Root?

First, we should talk about what “root” means.

A root is the basic unit of a word.

Linguists, scientists who study language, refer to the root as the base or foundation of a word. If you really think about it, the name “root” makes sense. A real, literal root is the base of a tree, connecting the tree to the ground. The root of a word connects that word to some meaning.

How to Use Roots to Form and Understand English Words

Now that you have a list of great roots to memorize, you’ll need a list of the most common prefixes and suffixes to go with it.


Prefixes and suffixes are two things that can be attached to roots to form words.

Suffixes can be attached at the ends of roots to change either the definition or the part of speech (noun, verb, adjective, etc.) of the word. So, suffixes can change verbs into nouns, nouns into adjectives and so on.

To create words you put a root together with either a suffix or prefix. Examples:

photo (root for light) + graph (suffix for written) = photograph (light that is written)

re (prefix for again) + flect (root for bend) = reflect (to bend again)

Now you might think these are funny ways to define the words “photograph” and “reflect.” This is because using Latin to define words means that you’re using very direct, literal translations.

However funny these translations might sound, there’s always a clue there that shows what the true meaning is in English.
