CSE Reviewer: Understanding Prefix and Suffix

Understanding the meanings of prefixes and suffixes along with root words will give you the ability to determine a word’s meaning without having to look it up. Having this knowledge will vastly improve your chances of passing the Civil Service exam in just your first take. Not only that, prefixes and suffixes are a really common part of the English language and it will come in handy once you need to use it! So learning how to use them correctly will help you boost your language skills enormously. Hopefully, the tutorial below will help you have a better grasp on prefixes and suffixes.

Prefix

Prefixes are syllables which we add to the beginning of a word to make a new word with a different meaning. Prefixes can, for example, create a new word opposite in meaning to the word the prefix is attached to. They can also make a word negative or express relations of time, place or manner. Check out some examples below:

Suffix

A suffix is a letter or group of letters added at the end of a word which makes a new word. The new word is most often a different word class from the original word. In the table below, the suffix –ful has changed verbs to adjectives, –ment, and –ion have changed verbs to nouns. If you see a word ending in –ment, for example, it is likely to be a noun (e.g. commitment, contentment).

Civil Service Reviewer on Suffixes

Word Suffix New Words
forget, use -ful forgetful, useful
state, govern -ment statement, government
complicate, create -ion complication, creation

 

Often, the suffix causes a spelling change to the root word. In the table above, the -e ending of complicate and create disappears when the –ion suffix is added. Other examples of spelling changes include:

  1. beautyduty + -ful → beautiful, dutiful (-y changes to i)

  2. heavyready + -ness → heaviness, readiness (-y changes to i)

  3. able, possible + -ity → abilitypossibility (-le changes to il)

  4. permitomit + -ion → permission, omission (-t changes to ss)
