Verb 'be': forming questions
To form a yes-no question, first think of the sentence in the positive form, then switch the positions of the subject and verb.
- Positive sentence: You are OK.
- Yes-no question: Are you OK?
In order to form a negative sentence, add the word 'not' after the verb 'be':
- Affirmative sentence: I am OK.
- Negative sentence: I am not OK.
The word 'not' is often contracted to 'n't': You're not OK = You aren't OK. He's not OK = He isn't OK. We're not OK = We aren't OK. They're not OK = They aren't OK.
"I am not OK." and "I'm not OK." are never contracted to "I amn't OK."
