Speech Acts:The theory that language is not just a means of describing the world, but a form of action that can change the world. Performative utterances are a specific type of speech act.
Illocutionary Force: The intended meaning or purpose behind a speech act, beyond just the literal meaning of the words used. Performative utterances derive their meaning from their illocutionary force.
Ritual:Ceremonial acts or practices that are imbued with symbolic meaning. Performative utterances are often found in ritual contexts, where the act of speaking enacts the ritual itself.
