But language wasn’t only for communication: it was also a form of action. According to speech act theory, statements like “You’re under arrest,” “I christen this vessel,” or “I promise” were all performative: a speaker could perform the action only by uttering the words. For such acts, knowing what would be said didn’t change anything. Everyone at a wedding anticipated the words “I now pronounce you husband and wife,” but until the minister actually said them, the ceremony didn’t count. With performative language, saying equaled doing.
