Three little letters — not — turn a positive comment (“I like your boots”) to a negative one (“I do not like your boots”). Apart from the fashion critique, what do you notice about the negative statement? The verb changes from like to do like. You need that extra part because “I not like” isn’t proper English. Negative verbs don’t always rely on a form of the verb do. Sometimes have, has, or had does the job. Sentences with a be verb can turn negative without any help at all. ~ Geraldine Woods
