VOCABULARY

Knowing the Roots
At least half of the words in the English language are derived from Greek and Latin roots. Knowing these roots helps us grasp the meaning of words before we look them up in the dictionary. It also helps us to see how words are often arranged in families with similar characteristics.

For instance, we know that sophomores are students in their second year of college or high school. What does it mean, though, to be sophomoric? The sopho part of the word comes from the same Greek root that gives us philosophy, which we know means love of wisdom. The ic ending is sometimes added to adjectival words in English, but the more part of the word comes from the same Greek root that gives us moron. Thus, “sophomores” are people who think they know a lot but really don’t know much about anything, and a sophomoric act is typical of a wise fool, a smart-aleck!

Let’s explore further. Going back to philosophy, we know the sophy part is related to wisdom and the phil part is related to love. What, then, is philanthropy? Phil is still love and anthropy comes from the same Greek root that gives us anthropology, which is the study of anthropos, or humankind. So a philanthropist must be someone who loves humans and does something about it–like giving money to find a cure for cancer or to build a Writing Center for the local community college. And while we’re at it, an anthropod is an animal who walks like a human being.

The good thing about words, including their roots and affixes, is that they are standard and unchanging. Once we know how to “dissect” them, it is quite easy to derive their meanings.

Affixes and Roots
Adding affixes to existing words to form new words is common in the English language. Prefixes are added to the front of the base word, whereas suffixes are added to the end of the base word. Prefixes usually do not change the class of the base word, but suffixes usually do.

Verbs
The most common prefixes used to form new verbs are: re–, dis–, over–, un–, mi–, out–. The most common suffixes are: –ize, –en, –ate, –ify. By far, the most common affix in academic English is –ize.
