Synonyms and antonyms are used to avoid over-using words. They help to build vocabulary and broaden your understanding of the world.


Synonyms are words with a similar or the same meaning. The word ‘syn’ means ‘the same.
Examples of synonyms:

Word Synonym
private secret
lucky fortunate
build construct
quarrel argue

Antonyms: are words that have opposite meanings. The word ‘anti’ means ‘opposite’ or ‘anti’.
For example

“The lion ambled up to its prey” is not as effective as “The lion stalked its prey” but they are both synonyms for the word ‘walk’.

Word Antonym
private public
lucky unlucky
build demolish, destroy
quarrel agree

A prefix/beginning can sometimes be added to a word to make an antonym.

Many of the prefixes used to make an antonym begin with ‘dis-’, ‘un-’, ‘im-’, ‘ir-’, ‘il-’ and ‘in-’.
For example
like – dislike
