Prefix and Suffix Types
We use a prefix at the beginning of the word to change the meaning and a suffix at the end of a word when we often use them to change the type of word. Understanding when to use prefixes and suffixes correctly are an important part of doing the word formation exercise , which is Part 3 in the Use of English exam.
To complete this series of posts on word building we’ll look at verb and adverb suffixes.
You can find a list of other posts on prefixes and suffixes on the First Exam Corner page.
Adverbs are the simplest types of words to form. To create many adverbs we add -ly to an adjective form.
- Quick -ly We just add -ly to the adjective.
- Careful -ly We now have two ‘l’s but only with the adverb.
- Happi -ly We need to change the form of the adjective first so y->i.
This is a small group of suffixes that refer to verb forms.
Verb Suffixes using -en
The meaning of the suffix -en is to “make” and we use adjectives or nouns +en to create new verbs.
bright -> brighten
dark -> darken
Note: We can also use en as a prefix. For example the verb ensure means to make sure.
Here are some further examples
In this group of adjectives we use the noun form to create the new verb
- strong -> strength -> strengthen
- long -> length -> lengthen
- high -> height -> heighten
