Hedging is a rhetorical strategy which speaker employs for lack of a full commitment either to the full category membership of a term or expression (content mitigation), or to the intended illocutionary force of the utterance (force mitigation). Hedging must be considered as an intentional action. The speaker chooses a linguistic device over the propositional content of the message which will affect the interpretation of the utterance; either modifies the content of the utterance or its force. Although hedges have no certain lexical meaning; they have powerful functional and pragmatic meaning.
