Negatives Adjectives

...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–.

Words that take im– as a negative prefix always begin with the letter m or p.

Words that take in– as a negative prefix can begin with a vowel (except i or u) or a consonant.

Words that take ir– as a negative prefix always begin with the letter r.

Words that take un– as a negative prefix may begin with a vowel or consonant.
