the ability for speech to be used not only to communicate but to fulfill an action and grant a binding power from that action.
An example of performative speech is the act of a couple saying “I do” at their wedding. Another example is a judge declaring a verdict. “The power of discourse to produce that which it names is thus essentially linked with the question of performitivity. The perfomative is thus one domain in which power acts as a discourse,” (Critically Queer, Butler).
