When you are reading, you will come across unfamiliar words. It is often possible to guess the
meanings of these words if you understand the way words in English are generally formed.
prefix→ stem ←suffix
An English word can be divided into three parts: a prefix, a stem, and a suffix. Pre - means 'before'. A prefix, therefore, is what comes before the stem. Consider, as an example, the prefix de- (meaning 'reduce' or 'reverse') in a word like demagnetize (meaning 'to deprive of magnetism'). A suffix is what is attached to the end of the stem. Consider, as an example, the suffix -er (meaning 'someone who') in programmer ('a person who programs'). Suffixes change the word from one part of speech to another. For example, -ly added to the adjective quick gives the adverb quickly. Prefixes, on the other hand, usually change the meaning of the word. For example, un- changes a word to the negative. Unmagnetizable means 'not capable of being magnetized'. Let us now consider some prefixes, their usual meanings, and how they change the meanings of English words.
