Finding Word Meaning Through Structure

You can often determine the general meaning of a word by its structure. Compound words have a root word, which might not be a whole word, either preceded by a prefix or followed by a suffix.

Although the English language, especially in the United States, has considerable influence from many different languages, most English root words and prefixes come from Latin or Greek and still carry the same meaning they did in the original language. Your job is to learn the most common prefixes and roots so you can determine a word's meaning from its structure. By learning the most common standard prefixes, roots, and suffixes, you can improve your vocabulary and spelling skills immensely.

Root Words

Root words generally keep the same meaning as they had in the original language, whether it be Latin, Greek, or another mother language. Most of our root words are derived from Latin and Greek; Table 3.2 provides a list of some of the most common Latin and Greek roots, what they mean, and examples of English words containing them.

Prefixes

Prefixes are standard syllables that attach to the front of root words to modify the root word and provide specificity and meaning. For example, the prefix pro added to the beginning of the root logue, results in the word prologue, which means "before the word, thought, or speech." When you think of multisyllabic words as simply puzzle pieces, it becomes much easier to determine their meanings. Table 3.3 provides a list of the most common prefixes you will see in everyday language.

Suffixes

Suffixes, yet another piece of the word structure puzzle, are standard syllables attached to the end of a word to modify and further specify its meaning. Although some suffixes add meaning to the root, most often the addition of a suffix also changes the part of speech (that is, verb, adjective, adverb, or noun) of the original word. In many cases, the suffix gives us clues to indicate which part of speech a particular word is.

For example, if you add an -ist suffix to the word art, you have artist, or one who displays the characteristics of art. In this case, both the root and the modified word are nouns. However, if you add an -istic suffix to the word art, you have artistic, which demonstrates a change of the root from a noun to an adjective. Table 3.4 demonstrates some common suffixes you should know.

NOTE

Inflectional endings, such as the plural -s, possessive -'s, past tense -ed, and comparative -er or -est, appear at the end of a word, but they do not change that word's grammatical function.
