Antonyms- Using Prefixes

Antonyms- Using Prefixes

An antonym is a word that is opposite in meaning to another word.

For example admit is the antonym of deny.

​

​There are other ways to form Antonyms

​Antonyms can also be made by adding prefix to a word. Prefixes are letters which we add to the beginning of a word to make a new word with a different meaning.

​These prefixes mean NOT

​DIS, IN, IL, IR, MIS, RE, UN, IM.

​Therefore, if placed before a word form the opposite meaning!

​Example

​agree - opposite would be to not agree

​ we can add the prefix dis- meaning not

​ so the antonym will be disagree

​agree- disagree

​Example

behave - opposite would be not behave

​ we can add the prefix mis- meaning not

​ so the antonym will be misbehave

behave- misbehave

​Here are more examples

​necessary-Unnecessary

forgivable-Unforgiveable

​Mature-Immature

Patient-Impatient

​

​Example

​legal - opposite would be not legal

​ we can add the prefix il- meaning not

​ so the antonym will be illegal

​legal- illegal
