I understood for performative verbs, if we are doing something and, at the same time, we are saying it, we don't need to use the present continuous tense. I am not sure I have it right.
For example, when I say, "I promise to do my homework," I am making the promise as I say this.
However, "promise" is not a stative verb, so we could say, "He is promising to do his homework."
Some sites say these are performative verbs, e.g. accept, acknowledge, advise, apologise, and warn, etc.
This site says,
Performative verbs: when you say a word you do the action the word describes
There is a group of verbs called "performative verbs". When you say these words, you actually do the action of the verb. If I say, "I apologise", by saying "apologise", I make my apology.
Compare this to a word like "run". If I say, "I run in the morning", then "run" just represents an action. Actually running is a different action. I cannot run just by saying "run".
What if I was running and saying, "I run," at the same time?
Does the performative principle apply to other verbs, such as "run" or "eat"?
Would the utterance, "I run," be grammatical if I was running while saying it?
