Package 3 - Prefixes and Affixes
Learning Outcomes
By the end of this section you should
✔ know the meanings of some common prefixes, suffixes and roots
✔ be able to infer the meaning of new words and enrich your vocabulary
✔ be able to organise your vocabulary study
Introduction
In the word, irregularity, ir- is a prefix, regular is a root and –ity is a (noun) suffix. It can be seen that affixes (i.e., prefix and suffix) can change the meaning of a word. It is important to learn roots and affixes since they often help you to work out the meaning of unfamiliar words while reading and also to determine parts of speech so that you are able to use these words correctly in speech or writing. Knowledge of roots and affixes can also give you a methodical technique for remembering new words by relating them to words you already know. With this technique, you can also organise words and learn them in groups, rather than individually.
Prefixes
Activity 1a Negative meaning formed with prefixes
Prefixes such as il-, im-, un-, dis-, in-, and ir- are often used to give adjectives a negative meaning. But it is not easy to master which prefix an adjective uses to form its opposite. It certainly helps if you are aware of the opposite, if there is any, of an adjective formed with a prefix the first time you try to learn the word. Type in the opposites of these words using an appropriate prefix.
