Linguistic Theory Lecture 1 Introduction: Linguistic Theory and Theories
Course Outline • Concentrating mainly on syntax • But some of the discussion will be of relevance to other areas of linguistics • We will look at phenomena and theories which were designed to them
Course Outline • The order of presentation will be historically oriented: • To understand current ideas, we need to know where they came from • You will not end up an expert in any particular theory – but you will know something about all of them
Why do we need theory? • Can’t we just observe language and describe it without bothering with difficult things like theories?
No matter what you do, there will always be a theory behind it • The human mind always operates with some notion of the way the universe works • this may not always be correct and it can be modified • The human mind finds it easier to understand things if we break it down into smaller pieces • But before we know something, how do we know where to place the divisions? • We don’t – we just guess • Guess = theory
We don’t have direct access to what we are studying • Most theories of linguistics take a cognitive perspective: • Language exists in people’s heads • Language is ‘rules’ that we know: competence • Linguistic knowledge is inaccessible to introspection and unobservable directly in others • So how do we study stuff that we cannot observe?
Language is a ‘black box’ puzzle: • You can observe what goes in and out of the box, but you can’t observe what goes on inside which changes the input to the output • By studying the input and output we can imagine what must be going on inside • Imagined processes = theory
A selective History of Linguistic Theory • American structuralism (C1900 – 1960) • Transformational Grammar (1957 – 1964) • Standard Generative Theory (1964 – 1980) • Government and Binding TheoryGeneralised Phrase Structure GrammarLexical Functional Grammar (1980 – present) • Minmalist ProgrammeOptimality Theory (1993 – present)
American Structuralism • Two characteristics: • Very impressed by Behaviourism/Empiricism • Studied Native American Languages
Behaviourism • Strong empiricist view: • All knowledge comes from experience • Therefore: • Human behaviour is learned from the environment • We can only study what we can observe • We cannot observe the mind, so we must assume that it does not exist • We can observe the environment and behaviour, so let’s assume this is all that exists • Behaviourism was the only school of psychology to define away its subject matter
Structuralists and Empiricism • We can only study what we can observe • We can observe sound • So we can study phonetics • If we assume that phonology is based on phonetics, we can study phonology too • If we assume that morphology is based on phonology, we can study morphology • If we assume that syntax is based on morphology, we can study syntax • We can’t study semantics – leave that to philosophers
Therefore: • The unit of phonology (phoneme) is a collection of phones (observable) and distinguished in terms of the distribution of phones • The unit of morphology (morpheme) is a combination of phonemes and distinguished in terms of distribution • The unit of syntax (word) is a combination of morphemes, distinguished by distribution
Strucuralists and Native Americans • There were not many native Americans left by 1900 and their languages were disappearing fast • There was therefore and urgent need to record their grammars • American languages were very different from Indo-European languages and it was thought that classical linguistic concepts did not apply
So what was needed was a set of ‘field tools’ that could be applied to any language which would accurately yield grammars • As all linguistic units were identified by distribution patterns, distribution was the most important ‘discovery procedures’ to produce a grammar
Generative Linguistics • 1952 Chomsky started to develop another view of language • 1957 published first book – very influential • But didn’t openly criticise Structuralism • 1959 published a critical paper of Behaviourism • Caused the collapse of Behaviourism • Structuralism soon followed
Basic Ideas • Rationalist approach • The mind exists and can be studied • Some knowledge comes from the mind itself • Discovery procedures are foolish and limiting • You get your data from wherever you can find it (not limited to observable data – i.e. Intuition also acceptable)
The notion of structure stays • Words group into phrases • Phrases group into sentences • New type of rule for producing structure • S NP VP • A set of such rules makes a Phrase Structure Grammar • Grammar is a set of rules that are part of the mind
But phrase structure rules are not enough to describe human languages • Discontinuous constituents • [A man with blue eyes] walked into a shop • [A man] walked into a shop [with blue eyes] • To describe this phenomena we need transformations • Rules which alter structures to form other structures (e.g. By moving things about)
Generative grammar and language acquisition • From a rationalist perspective, knowledge of language could be innate • But clearly this is not totally true as there is more than one language • Chomsky supposed that some aspects of language are innate but some are learned
Language learning must be easy • Children do it in about 5 years with no formal instruction • But transformational grammars which are capable of describing even basic linguistic facts were very complicated • How can we square these facts?
Developments of the 1970s • The way to account for language acquisition is to assume that grammars are limited • You can’t just suppose any kind of rule • Therefore the focus was not on what we can do with transformation, but what we can’t • Constraints
Developments of the 1980s • Principles and Parameters • Principle • Universal • Invariant • Innate • Parameter • A limited number of choices • Needs linguistic data to set
Modularity • Principles and parameters seemed to group into a small number of components, each of which addresses specific linguistic phenomena • Thus the grammatical system was seen as constructed from a set of simple modules which interact in complex ways • Thus the grammar is simple, but capable of providing complex analyses
Developments of the 1990s • Competition • non-absolute grammaticality • Grammaticality based on the ‘best’ of several options • E.g. • It is better to not move than to move • It is better to move short distances than long ones
What does the grammar manipulate? • From structuralism we have always assumed that words are the basis of syntax • But transformational analyses started to discover that units smaller than words undergo syntactic processes: • He is always sad • He always phones his mother • Some have suggested that this leads to a theory where syntax always manipulates items smaller than the word and that words are constructed by syntax
