WORD PARTS FOR
COMMUNICATIONS MODULES

This section is designed to introduce you to common parts of words: roots, prefixes, and suffixes. If you have already completed this section in another station you are free to skip it or to review the parts.

A train is one way to represent word parts.

train

The engine represents the root - the main part of the word that gives it meaning. The cars in a train represent other parts that you can add to the root to change the meaning of the word. Prefixes come before the root. Suffixes come after the root.

Maybe you can think of a better symbol to understand the parts of words. Would a dog, its tail and its nose work as a symbol? How about a tractor with a working part in front and another in the back? Draw your own picture once you understand the idea.

ROOTS, PREFIXES, AND SUFFIXES

Knowing how to identify repeated parts of words can be very helpful. It will help you understand new words better. It will definitely help you understand medical terms that look long and difficult if you take them apart.

There are three parts that can be used with or added to words to change their meaning:

prefix train
1. Prefixes – prefixes are parts that are added at the beginning of a basic word. For example, the prefix “pre” means before. If you add the prefix “pre” to the word “trial” you get “pretrial,” which means something that happens before a trial. So a prefix comes before the word.

suffix train
2. Suffixes – Suffixes are letter combinations added to the end of words. They will often change the function of a word in a sentence. For example, take the word “bone.” Add the suffix “less” to the word, and you change it to an adjective. Nouns name things. Adjectives describe them.

root train
3. Roots – The root of a word is what is left when you take away its prefixes and suffixes. In the tables above, the root is in the column that says, “Main Part of the Word.” That is the root.
