politeness

politeness

n. the process by which a speaker attempts to avoid harm to a listener’s public image or private self-concept through the use of nonthreatening or face-saving forms of speech. Politeness involves steering clear of content or forms of language that might embarrass listeners, make them feel uncomfortable, or lessen their self-respect. It also involves actively using language that maintains or enhances the listener’s dignity, prestige, and autonomy. For example, a speaker might preface the request for a favor by saying, “I’m sorry to bother you, and feel free to say no, but I wonder if you would. . . .” Politeness is one aspect of facework.
