Word building in English

English is a very flexible language and you can build on your vocabulary and learn how to make new words.
One way of doing this is to add prefixes (such as dis, pre or co) before the word.

Here's a list of common prefixes with their meanings and some examples.

anti (= against)
antibodies, anti-social

auto (self)
autonomous, autobiography, automobile

bi (= two)
bicycle

co (= with)
cooperate, coordinate

contra (= against)
contradict, contravene

de (= remove)
deregulate, deselect

dis (= not)
disappear

il (= not)
illegal

im (= not)
immaterial, immature

inter (= between)

Word Endings

You can also make new words from the words you already know by using different endings. For example, "The person who employs me has a fast car". You can make this sentence simpler, by replacing "the person who employs me" with "my employer". This gives you "My employer has a fast car."

In English you can make nouns from verbs (to employ gives employer and employee). You can also make verbs from nouns or adjectives: government gives to govern, modern gives to modernise and so on. Learning what endings you can put on words means you can expand your vocabulary and say what you mean more easily.
