Day 5 Branch Out with Word Roots
Part II Find Out That New Words Equal the Sum of Their Parts

There are no shortcuts in test preparation…or are there? You will have to memorize lists of words; after all, some test-worthy words can only be learned through memorization. But you can also acquire heaps of test-worthy words by mastering only a handful of roots. This is a great shortcut: it’s fun, it’s easy, and, best of all, it works!

A root is a stem or base form for many words. It has been estimated that 90 percent of all English words can be traced back to classical Greek and Latin roots.

How Roots Work

1. Prefixes and Suffixes Are Added to Roots to Create Many Words.

For example, the root vor means “to eat.” If you are a voracious (voh-ray-shus) eater, you eat a lot of food. In the following examples, the root “vor(e)” is combined with prefixes and suffixes to describe types of eaters in the plant and animal kingdoms.

Cover the last column and see how many of these words you can figure out by just knowing the meaning of the root “vor.”

nectarivore

omnivore

everything

vor

Knowing how the words were created can help you figure out many words you encounter on standardized tests. In addition, you can use these decoding skills to figure out the meaning of all the new words that are created every day. (You’ll learn more about suffixes in Day 6.)

Here’s the basic drill:

Adding a prefix to a root

Adding a suffix to a root

de + hydrate = dehydrate

zoo + ology = zoology

hydro + power = hydropower

bronch + itis = bronchitis

The following chart shows additional examples of how words are put together. Knowing this process can help you take them apart to define them. Remember, words are like people: it’s easy to figure them out… once you know their parts.

Whenever you come upon an unfamiliar word, first check to see if it has a recognizable root. Even if you can’t define a word exactly, recognizing the root will give you a general idea of the word’s meaning. For example, if you read the word geocentric, knowing the root geo would help you figure out that geocentric has to do with the center (“centric”) of the Earth or Earth as the center.

2. A Word Can Contain More Than One Root.

For example, the word matrilineal contains the roots matri (mother) and lineal (line). Putting it together, you can deduce that matrilineal means “determining ancestry through the female line.”

3. Some Roots Are Words Themselves.

For example, the root term also means “name or length of time.” In a similar way, the root vent also means “an opening that allows air to enter.” Even though these roots are words, they can still function as roots, as the following chart shows:

4. Some Roots Must Be Combined with Other Word Elements to Form Words.

Take a look at the examples on the following chart:

5. When It Comes to Building Words from Roots, Placement Matters.

Some roots can also function as prefixes, depending on their placement in a word. For example, graphy means “writing.”
