My textbook says:
Some verbs used as performatives with the present simple in affirmative (= positive) sentences (apologize, deny, guarantee, promise) have a similar meaning with either the present simple or the present continuous in negative sentences . . .
As an example, the textbook gives the following sentence:
I don’t deny / I’m not denying taking the books, but Miguel said it would be okay.
I understand that both the present simple and the present continuous can work with performatives in negative sentences.
But the textbook says it works only with “some verbs used as performatives in affirmative sentences . . .” Do I understand correctly that there are some verbs used as performatives to which this rule (using the present continuous in negative sentences) doesn’t apply?
