Prefixes and suffixes

What are prefixes and suffixes, as well as infixes? First off, an affix is an element such as a prefix or suffix that attaches to another word. We attach affixes (prefixes, suffixes, and infixes) to words in order to create new words. So, just by knowing the most common prefixes and suffixes, you can increase your vocabulary without having to learn any new words! Let’s take a look at the chart below.

Remember, prefixes go at the beginning of a word and suffixes at the end of a word.

A quick example of prefixes and suffixes for the word 'doubt'

Affix (prefix or suffix) New word Example
/ / I doubt you’ll be able to resolve the problem.
/ / There are still many doubts, I’m afraid.
Adjectival suffix: –ful. Doubtful I’m doubtful about your plans.
Adverbial suffix: –ly. Doubtfully He worked doubtfully.
Adjectival suffix meaning “without” or “not having”: –less. Doubtless We’re doubtless because we have no idea.
Prefix meaning “negation”: –un. Undoubted I am the undoubted champion of the world.
Prefix meaning “negation”: –un + adverbial suffix: –ly. Undoubtedly Undoubtedly, you were right.

By just knowing prefixes and suffixes, you can increase your vocabulary fivefold! As can be seen from the chart above using the word 'doubt' of which we have five new words: doubtful, doubtfully, doubtless, undoubted and undoubtedly.

How prefixes and suffixes work

‘Affix’ is basically the umbrella term for all prefixes, suffixes, and infixes, (infixes are rare in English but very common in Spanish).

One really needs to understand prefixes (attached to the beginning of the word) and suffixes (attached to the end of the word) in order to speak English really well.

Correct implementation of prefixes and suffixes will allow you to completely alter or change the meaning of a word with ease and without having to change the whole sentence.

Moreover, there are not too many prefixes and suffixes, however, the problem resides in the fact that there is no rule to their correct implementation.

For example, the prefix ‘im’ negates ‘polite’ and not ‘in’, therefore, the correct negation for the adjective ‘polite’ is ‘impolite’.

The prefix ‘im’, just like all other prefixes, must be learned by heart or by memory, but nevertheless, it’s really not difficult to remember! Below, I’ll outline correct affix usage (prefixes and suffixes) with examples.

Remember, affixes alter: verbs, adjectives, and adverbs.
