大豆卵磷脂胶囊WORD STUDY: Stem and Affixes
Using context clues is one way to discover the meaning of an unfamiliar word. Another way is word analysis that is, looking at the meanings of parts of words. Many English words have been formed by combing parts of older English, Greek, and Latin words. If you know the meanings of some of the word parts, you can often guess the meaning of an unfamiliar English word.
For example, report is formed from re, which means back, and port which means carry. Scientist is derived from sci, which means know, and ist, which means one who. Port and sci are called affixes, that is, word parts which are attached to stems. Affixes like re, which are attached to the beginning of stems are called prefixes. Affixes attached to the end, like list, are called suffixes. Generally, prefixes change the meaning of a word and suffixes change its part of speech. Here is an example:
Stem pay (verb) honest(adjective)
Prefix repay (verb) dishonest(adjective)
Suffix repayment (noun) dishonestly(adverb)
Word analysis is not always enough to give you the preci definition of a word you encounter in a rea
ding passage, but often it will help you to understand the general meaning of the word so that you can continue reading without stopping to u a dictionary.
Below is a list of some commonly occurring stems and affixes. Study their meanings. Your teacher may ask you to give examples of words you know which are derived from the stems and affixes. Then do the exercis which follow. Some questions require the u of a dictionary.
