How to Make Opposite Words Using Prefixes

In English, we can often change the meaning of a word to its opposite by adding a prefix. A prefix is a group of letters added before a word. Common prefixes used to form opposites are:

• un- (e.g., unhappy)
• in-, im-, il-, ir- (e.g., incorrect, impossible, illegal, irregular)
• dis- (e.g., disagree)
• non- (e.g., nonverbal)
