A prefix is a letter or a group of letters that attaches to the beginning of a word and helps to indicate or modify its meaning. An easy example would be the word 'prefix' itself! It begins with the prefix pre-, which means 'before'.
It is quite important to understand what different prefixes mean as they can help to understand the meanings of any new vocabulary that you learn. However, you do need to be careful, as sometimes a prefix can have more than one meaning!
An example would be im-, this can mean 'not' or 'into'.
A suffix is a letter or a group of letters that is usually attached to the end of a word to form a new word, as well as alter the way it functions grammatically.
Depending on whether it is a noun, verb, adjective or adverb, a different suffix would be required. For example, the verb read can be altered to become the noun reader by adding the suffix -er. The same verb can also be turned into the adjective readable by adding the suffix –able.
It is just as important to understand the definitions of suffixes as prefixes, because they too help us to deduce the meanings of any new words that we learn.
So as you can see, affixes can dramatically change the definitions of words. Knowing the various prefixes and suffixes along with their meanings can really help you to understand how words are used, and also how they should be spelt.
Although these groups of letters (affixes) are important and assist with forming words, they are not words in their own right and cannot stand alone in a sentence.
If they are printed or written alone, then they should have a hyphen before or after them to demonstrate that they are to be attached to other letters to form words .
When you are learning the different types of prefixes, it is important to remember that not every word containing these combinations is a prefix. Sometimes words have 'combining forms', which look very similar to prefixes but work differently!
As you know, a prefix is a letter or a group of letters that appears at the beginning of words, but it can also be removed from the base word, and the word would still be a word without it, even if the meaning changes.
For example, non- means 'not' or 'without', this is used in words such as 'nonsense'. The word 'sense' can be separated from the prefix and it would still be a word on its own, even if the meaning is different.
Combining forms are similar to prefixes, and are sometimes known as ‘chameleon prefixes’, because they act like them and appear at the beginning of words like them, BUT the combining form is intrinsic to the word, meaning it is a part of the word and cannot be removed.
They are called 'chameleons', because they change their spelling and physical form to suit the word they are attached to!
So, combining forms act as prefixes but are different, because the remaining letters cannot be separated to form an independent word.
