J.L Austin, a British linguistic, divides words into two categories:
Constative: Sentences that describe something as true or false.
Performative: Sentences that denote an action in instead of conveying a message.
Both of them depend on the context and the reception. The performative are logical, they are known as FELICITY CONDITIONS:
- Able to be executed
If the performative does not meet these conditions, then it does not have the power to denote an action. But just because a performative meets its conditions and it is clearly stated, it does not mean that it is implicity followed.
Speech acts: when words are actions.
