Language change
Language change is variation over time in a language's features. It is studied in several subfields of linguistics: historical linguistics, sociolinguistics, and evolutionary linguistics. Some commentators use the label corruption to suggest that language change constitutes a degradation in the quality of a language, especially when the change originates from human error or is a prescriptively discouraged usage. Modern linguistics typically does not support this concept, since from a scientific point of view such innovations cannot be judged in terms of good or bad. John Lyons notes that "any standard of evaluation applied to language-change must be based upon a recognition of the various functions a language 'is called upon' to fulfil in the society which uses it".
Causes
- Economy: Speech communities tend to change their utterances to be as efficient and effective as possible, while still reaching communicative goals. Purposeful speaking therefore involves a trade-off of costs and benefits.
- * The principle of least effort tends to result in phonetic reduction of speech forms. See vowel reduction, cluster reduction, lenition, and elision. After some time a change may become widely accepted and may end up treated as standard. For instance: going to → gonna or, with examples of both vowel reduction and elision,.
- Expressiveness: Common or overused language tends to lose its emotional or rhetorical intensity over time; therefore, new words and constructions are continuously employed to revive that intensity
- Analogy: Over time, speech communities unconsciously apply patterns of rules in certain words, sounds, etc. to unrelated other words, sounds, etc.
- Language contact: Words and constructions are borrowed from one language into another.
- Geographic separation: When people with one language move away from each other, the language will gradually diverge into separate dialects, due to different experiences.
- Cultural environment: As a culture evolves, new places, situations, and objects inevitably enter its language, whether or not the culture encounters different people.
- Migration/Movement: Speech communities, moving into a region with a new or more complex linguistic situation, will influence, and be influenced by, language change; they sometimes even end up with entirely new languages, such as pidgins and creoles.
- Imperfect learning: According to one view, children regularly learn the adult forms imperfectly, and the changed forms then turn into a new standard. Alternatively, imperfect learning occurs regularly in one part of society, such as an immigrant group, where the minority language forms a substratum, and the changed forms can ultimately influence majority usage.
- Social prestige: Language may not only change towards features that have more social prestige, but also away from ones with negative prestige, as in the case of the loss of rhoticity in the British Received Pronunciation accent. Such movements can go back and forth.
Types
All languages change continually,and do so in many and varied ways.
Marcel Cohen details various types of language change under the overall headings of the external evolution
and internal evolution of languages.
Lexical changes
The study of lexical changes forms the diachronic portion of the science of onomasiology.The ongoing influx of new words into the English language helps make it a rich field for investigation into language change, despite the difficulty of defining precisely and accurately the vocabulary available to speakers of English. Throughout its history English has not only borrowed words from other languages but has re-combined and recycled them to create new meanings, whilst losing some old words.
Dictionary-writers try to keep track of the changes in languages by recording the appearance in a language of new words, or of new usages for existing words. By the same token, they may tag some words eventually as "archaic" or "obsolete".
Phonetic and phonological changes
The concept of sound change covers both phonetic and phonological developments.The sociolinguist William Labov recorded the change in pronunciation in a relatively short period in the American resort of Martha's Vineyard and showed how this resulted from social tensions and processes.
Even in the relatively short time that broadcast media have recorded their work, one can observe the difference between the pronunciation of the newsreaders of the 1940s and the 1950s and the pronunciation of today. The greater acceptance and fashionability of regional accents in media may also reflect a more democratic, less formal society — compare the widespread adoption of language policies.
The mapping and recording of small-scale phonological changes poses difficulties, especially as the practical technology of sound recording dates only from the 19th century. Written texts provide the main evidence of how language sounds have changed over the centuries. But note Ferdinand de Saussure's work on postulating the existence and disappearance of laryngeals in Proto-Indo-European as an example of other methods of detecting/reconstructing sound-changes within historical linguistics. Poetic devices such as rhyme and rhythm may provide clues to previous phonological habits.
Spelling changes
Standardisation of spelling originated centuries ago. Differences in spelling often catch the eye of a reader of a text from a previous century. The pre-print era had fewer literate people: languages lacked fixed systems of orthography, and the handwritten manuscripts that survive often show words spelled according to regional pronunciation and to personal preference.Semantic changes
Semantic changes are shifts in the meanings of existing words. Basic types of semantic change include:- pejoration, in which a term's connotations become more negative
- amelioration, in which a term's connotations become more positive
- broadening, in which a term acquires additional potential uses
- narrowing, in which a term's potential uses are restricted
Words' meanings may also change in terms of the breadth of their semantic domain. Narrowing a word limits its alternative meanings, whereas broadening associates new meanings with it. For example, "hound" once referred to any dog, whereas in modern English it denotes only a particular type of canid. On the other hand, the word "dog" has been broadened from its Old English root 'dogge', the name of a particular breed, to become the general term for all canines.
Syntactic change
is the evolution of the syntactic structure of a natural language.Over time, syntactic change is the greatest modifier of a particular language. Massive changes – attributable either to creolization or to relexification – may occur both in syntax and in vocabulary. Syntactic change can also be purely language-internal, whether independent within the syntactic component or the eventual result of phonological or morphological change.
Sociolinguistics
The sociolinguist Jennifer Coates, following William Labov, describes linguistic change as occurring in the context of linguistic heterogeneity. She explains that "inguistic change can be said to have taken place when a new linguistic form, used by some sub-group within a speech community, is adopted by other members of that community and accepted as the norm."Can and Patton provide a quantitative analysis of twentieth century Turkish literature using forty novels of forty authors. Using weighted least squares regression and a sliding window approach, they show that, as time passes, words, in terms of both tokens and types, have become longer. They indicate that the increase in word lengths with time can be attributed to the government-initiated language "reform" of the 20th century. This reform aimed at replacing foreign words used in Turkish, especially Arabic- and Persian-based words, with newly coined pure Turkish neologisms created by adding suffixes to Turkish word stems.
Can and Patton, based on their observations of the change of a specific word use, also speculate that the word length increase can influence the common word choice preferences of authors.
Kadochnikov analyzes the political and economic logic behind the development of the Russian language. Ever since the emergence of the unified Russian state in the 15th and 16th centuries the government played a key role in standardizing the Russian language and developing its prescriptive norms with the fundamental goal of ensuring that it can be efficiently used as a practical tool in all sorts of legal, judicial, adimistrative and economic affairs throughout the country.
Quantification
Altintas, Can, and Patton introduce a systematic approach to language change quantification by studying unconsciously-used language features in time-separated parallel translations. For this purpose, they use objective style markers such as vocabulary richness and lengths of words, word stems and suffixes, and employ statistical methods to measure their changes over time.Language shift and social status
Languages perceived to be "higher status" stabilise or spread at the expense of other languages perceived by their own speakers to be "lower-status".Historical examples are the early Welsh and Lutheran Bible translations, leading to the liturgical languages Welsh and High German thriving today, unlike other Celtic or German variants.
For prehistory, Forster and Renfrew argue that in some cases there is a correlation of language change with intrusive male Y chromosomes but not with female mtDNA. They then speculate that technological innovation or military prowess causes immigration of at least some males, and perceived status change. Then, in mixed-language marriages with these males, prehistoric women would often have chosen to transmit the "higher-status" spouse's language to their children, yielding the language/Y-chromosome correlation seen today.
