Bidialectism - the use of the national standard and a regional dialect. Lexical gaps - the theory that a new word or meaning creates room in the lexicon for related forms e.g. Brexit = brexiter, brexiting. Norman Fairclough Conversationalisation - convergence of spoken and written discourse. S-curve - model that describes the speed at which a new word or meaning grows in use e.g. a gradual start, then rapid increase, then a levelling off. Infectious disease theory - We 'catch' changes from those around us and we ought to fight such diseases. However, perhaps it is not a disease because people want to change due to sociolect - they want to fit in with the language that specific social groups use. This metaphor challenges the idea that changes in language are like a virus. Crumbling castles theory - Language should be preserved intact, but language has never been perfect and must continue to change in order to cope with changing social circumstances. This metaphor is used to challenge the idea that language change means language decay. Argues against a prescriptive view of language, which identifies a vast network or rules and checks usage against these rules. Complaints by prescriptivists are often not about failure to communicate but failure to communicate in a certain way. Damp spoon theory - Language has not become lazy - the only true lazy language is drunken language. Used as a metaphor to challenge the idea that some language is ugly or distasteful. 1 - Potential - a need for a new word arises because of something new in the world. 2 - Implementation - a few people start to use the new language 3 - Diffusion - the innovation spreads and is used more widely. 4 - Codification - the new language enters the dictionary and is used as a standard for of language. Stages to explain how new words enter the language. Linguistic determinism - language and its structures limit and determine human knowledge or thought, as well as though processes such as categorisation, memory and perception. This implies that people of different languages have different thoughts. Conversationalisation and personalisation Advertisements and marketing texts are increasingly attempting to mimic speech - includes synthetic personalisation. Standardisation making all variations of language conform to one version. Archaic - a word that is only rarely used in common language and we associate with older modes of speech. Suzanne Romaine The internal and external history of language. Internal (PRESCRIPTIVIST) = formation of new words and the influence of dictionaries. Looks at what happens inside the language with no external influences. Sapir-Whorf Focuses on the influence of different varieties of language e.g. dialects, sociolects, occupational lexis. Focuses on how they change mainstream language use. Explains borrowing, hyper-correction, omission and other ways in which language changes. External (DESCRIPTIVIST) = the changing of social contexts. Looks at language as an ongoing process. Halliday Substratum theory Explains how a dominant incoming language is altered by contact with a native language. Functional theory - explains that language changes to meet new needs. Explains the use of archaisms and slang. Random fluctuation - language is inherently unstable and change is unpredictable. Random events and errors lead to language change as a consequence of ever-changing contextual factors. Charles Hockett Language change theories and concepts Sharon Goodman Jean Aitchison Informalisation = the process whereby language forms that were traditionally reserved for close personal relationships are now used in wider social contexts. The way in which language is becoming increasingly informal in all areas of society. Economisation - a more compressed style of writing to communicate information more efficiently. The Queen's English Society - Represent an autocratic movement and are prescriptive in their view of language and language change. Young cuckoo process - New words slowly get used more than the old and eventually the new word will replace the old. Etymological argument - basis for criticising any use of words such as 'decimate' with a more general sense than their original meaning. Wave model - explains how changes diffuse through geographical and social space, likely ripples on a pond. Evolution - suggestion that language has developed and adapted rather than decayed. Reflectionism - the idea that language changes in response to changes in our thoughts. Prescriptivism - a language ideology that makes judgements about what is right and wrong. David Crystal Uses the term 'asynchronous' to describe groups where postings are placed on boards in chat-rooms and 'synchronous' to describe groups of people who chat in real life. Codification - the establishment of spelling and grammar rules for language. Descriptivism - a language ideology that seeks to describe without making value judgements. Obsolete - a word that is no longer used. Colloquialisation - where writing uses language more typically seen in spoken registers. Drift - the slow shifting of a word's meaning over time. Einar Haugen Schizoglossia - an anxiety about which is the right form of language to use at a particular moment.
