This readable book presents a new general theoretical understanding of politeness. It offers an account of a wide range of politeness phenomena in English, illustrated by hundreds of examples of actual language use taken largely from authentic British and American sources. Building on his earlier pioneering work on politeness, Geoffrey Leech takes a pragmatic approach that is based on the controversial notion that politeness is communicative altruism. Leech's 1983 book, Principles of Pragmatics, introduced the now widely-accepted distinction between pragmalinguistic and sociopragmatic aspects.
