Word Formation


A Introduction

Look at the examples

Lots of people believe that God exist.

Lots of people believe in the existence of God.


Exist is a verb and existence is a noun. The word existence has two parts: exist- and -ence. We call -ence a ‘suffix’. We add it to the end of the verb exist to form a noun.


We can also use suffixes to form verbs, adjectives and adverbs.

The system is being modernized. (make modern)

I grew up in an industrial town. (a town where there is a lot of industry)

The man was behaving strangely. (in a strange way)


There are many different suffixes, such as -ence, -ize, -al, -ly, -tion and -ment. Some of them can be used to form many different words. For example, there are a lot of nouns ending in -tion: action, education, explanation, information, instruction, etc. There are no exact rules about which suffix you can add to which word. Adding a suffix can also involve other changes to the form of a word.

industry→industrial repeat→repetition science→scientist


Now look at these examples.

They’re going to play the match on Wednesday.

They’re going to replay the match on Wednesday.

We can add re- to the beginning of the verb play. We call re- a ‘prefix’. A prefix adds something to the meaning of a word. The verb replay means ‘play again’. We can also add prefixes to nouns and adjectives.
