Malamud Intro to Linguistics Historical linguisticsWhat are the results of language change?When accompanied by splits of populations, language change results first in dialect divergence (the kinds of differences we see between British and American English; between the French of France and of Quebec; between New World and Old World Spanish and Portuguese). • Initial problems with intelligibility begin long before we would consider talking about separate languages. Certain systematic comprehension difficulties can occur even within relatively closely related dialects. E.g. - Chicago vs Philadelphia speakers in your homework.Over longer time periods, we see the emergence of separate languages, and when a group of languages all descend from a common parent, we call them a family. 1. The puzzle of language change • Language is constantly changing. This presents us with a puzzle: o language change hinders communication, o and it is also negatively evaluated by socially dominant groups. Nevertheless it is a universal characteristic of human language and cannot be stopped. 1.1 How and why does language change? Changes can take originate from language learning, or through language contact, social differentiation, and natural processes in usage. • Language learning: the process of linguistic replication is imperfect, result is variable across people.o A bias in the learning process -- for instance, towards regularization of paradigms (e.g. the replacement of older holp by helped) -- can cause systematic drift, generation by generation. o But frequently, the mutation of a language through imperfect learning is essentially random. • Language contact: in contact situations, languages often borrow words, sounds, constructions etc. • Social differentiation: social groups adopt distinctive norms of dress, adornment, gesture, speech. o Many instances of language change, especially those which differentiate one dialect or language from another, start out as markers of some social group. o Sociolinguistic research has shown that all changes have a social dimension while they are in progress, with one social group or another leading the change and others following behind. • Natural processes in usage: 1) Rapid or casual speech naturally produces processes such as assimilation (pronouncing neighboring sounds more like each other), dissimilation (pronouncing neighboring sounds less like each other), syncope (eliminating a vowel in the middle of a word) and apocope (eliminating a vowel at the end of the word). o Through repetition, particular cases may become conventionalized, and therefore produced even in slower or more careful speech. 2) Certain changes arise from pressure to maintain a certain amount of symmetry in the linguistic system. This is especially so in changes in vowel systems. If one vowel changes its pronunciation significantly, it often pulls the rest of the system with it.3) Word meanings can change in a similar way, through conventionalization of processes like metaphor and metonymy. o E.g., meaning of trivial went from "pertaining to the trivium, the elementary areas of study" to "simple or easy to the point of being meaningless" - 1 -1.2 But why? If we have a language instinct, why aren't we born knowing all of the details of language? • Then we could all talk to each other; children wouldn't have to spend so much time learning to speak. Pinker gives evolutionary reasons why language blueprint is instinct, but details are learned. • This allows flexibility and extensibility, e.g. creation of new words for new concepts. • It gives a way for people to sync up their language if, by a genetic mutation, their UGs diverge a bit. Why doesn’t language eventually go into some perfect state where pronunciation is as easy as possible, and the system is perfectly symmetrical? • Changes resulting from internal pressures seem to be a constant balancing act, • an attempt to maintain an equilibrium that is constantly disturbed by other changes. 1.3 The analogy with evolution via natural selection Darwin himself made an analogy between evolution of species via natural selection and language change.• At any given time within a population, there is variation. Some variants survive and others are eliminated. Overall effect is a drift from an older set of characteristics to a newer set of somewhat different traits. • Different species emerge when members of one population cannot breed successfully with members of the other. Different languages arise when members of the two populations can no longer understand each other. There are some key differences between grammars and genotypes: • Linguistic traits can be acquired throughout one's life from different sources, though initial acquisition & (to a lesser extent) adolescence seem to be crucial stages. • Acquired (linguistic) traits can also be passed on to others. • Linguistic history need not have the strict form of a tree, with languages splitting but never rejoining, whereas genetic evolution is largely constrained to be tree-like. Practically, the assumption that linguistic history is tree-like is a good working approximation. The basic sound structure and morphology of languages usually seems to "descend" via a tree-structured graph of inheritance, with regular, lawful relationships between the patterns of "parent" and "child" languages. 2. Types of Change All aspects of language change. We can think about this in terms of changes in subparts or modules of the grammar, in the syntax, phonology, semantics, morphology, and pragmatics. 2.1 Pragmatic shifting A syntactic construction with a particular pragmatic function may acquire a new function over time. • For instance, many languages have impersonal pronouns that start out as nouns meaning “person” E.g., English one and French on from Latin homo=“person”; German man from German mann=“man”). • Eventually they come to be used in generic contexts, like One is always uneasy in such situations• Sometimes, the function of these pronouns expands further – they are also used in non-generic contexts with a passive meaning: French On a tué le président = ON has killed the president = The president was killed German Man hat ein Haus abgebrannt = MAN has burned a house = A house was burned • Eventually, these constructions may encroach on the actual passive so much that the passive will go out of use entirely. In this way, pragmatic
