Relevance theory aims to explain the well recognised fact that communicators usually convey much more information with their utterances than what is contained in their literal sense. To this end, Sperber and Wilson argue that acts of human verbal communication are ostensive in that they draw their addressees' attention to the fact that the communicator wants to convey some information. In this way they automatically assert that they are "relevant" to their addressees. A relevant utterance in this technical sense is one from which many conclusions can be drawn at a low processing cost for the addressee.
