Performative language refers to words where something is done in its speaking, i.e., when something is accomphished as soon as the words are uttered. Examples include "I do" when a bride or groom responds to the minister's question, "Do you take this . . . man/woman to be your . . .?" In saying the words, the bride/groom makes herself/himself married (even without the official declaration "Now I pronounce you . . . ").
