A prefix is a group of letters (affixes) added in front of a word or a root of the word to change its meaning. A negative prefix is a prefix which carries a negative meaning 'not' , 'opposite of'.
Negative statements are the opposite of affirmative statements. In English, one way to make negative statements is by adding negative prefixes to nouns, adjectives, and verbs. Here are some English negative prefixes: a-, dis-, il-, im-, in-, ir-, non-, un-.
For example, the prefix un- can be attached to the adjective happy to create the negative adjective unhappy. Or you can use the negative adverb not. Note that there is no difference in meaning between these two forms.
