Syntax: the study of the structure of
sentences and the grammatical rules
governing the way words are combined to
form sentences.

Prescriptive Grammar
Traditional Grammar and the prescriptive
approach: Grammar as ‘linguistic etiquette’,
i.e. the identification of the best/proper
structures to be used;
© BTexact Technologies 2001
Descriptive Grammatical Rules

Descriptive rules are more general and more
basic than prescriptive rules in the sense
that all sentences of a language are formed
in accordance with them, not just the subset
of sentences that count as correct or socially
acceptable.
© BTexact Technologies 2001
Prescriptive Rules

Grammar is a collection of rules concerning
what counts as socially acceptable and
unacceptable language use. These rules in
question primarily concern the proper
composition of sentences in written
language.
-
Don’t start a sentence with a conjunction
Don’t end a sentence with a preposition
Don’t use sentence fragments
Don’t use dangling participles
Don’t use a plural pronoun to refer back to a singular noun;
etc.

e.g. Over there is the guy who I went to the party with

Descriptive Grammar

Rules of descriptive grammar have the status of
scientific observations, and they are intended as
insightful generalizations about the way that human
language is used in fact, rather than about how it
ought to be used.
Articles precede the nouns they belong to
- Relative clauses follow the noun that they modify
Prepositions precede their objects
© BTexact Technologies 2001
Grammatical sentences

An ungrammatical sentence is conventionally
prefixed with an asterisk (*) while the grammatical
sentences are usually not specifically marked.
- ( ) Over there is guy the who I went to party the
with
- ( )Over there is the man I went to the party with
guy
- ( )Over there is the guy who I went to the party
with
- ( )Over there is the guy with whom I went to the
party

 Rules about correct or

variants

…The verb SHOULD agree
in number with the logical
subject

Rules about all sentences of
a language
 Rules followed effortlessly
and consistently

discrimination

…the verb CAN agree in
number with EITHER the
expletive subject OR with the
logical subject

Universal Grammar

Grammar as a form of internal linguistic
knowledge that operates in the appropriate
production and comprehension of natural
languages.
© BTexact Technologies 2001
Goals of a theory of grammar
-
-
-
-
Universality: a theory of grammar should provide us with
the tools needed to describle the grammar of any natural
language adequately.
Descriptive adequacy: a grammar of a given language
has descriptive adequacy if it explains observed language
data and the intuitions of native speakers about the
grammaticality of sentences of a language
Explanatory adequacy: a theory of grammar has
explanatory adequacy if it explains how native speakers
of a language can arrive at the knowledge of that
language.
Learnability: an adequate linguistic theory must provide
adequate grammars which are learnable by young
children in a relatively short period of time. i.e., it must
account for the uniformity and rapidity of language
acquisition, given the poverty of stimulus.

American Structuralism: A brief history




Descriptive linguistics is the study and analysis of spoken language. The
techniques of descriptive linguistics were devised by German American
anthropologist Franz Boas and American linguist and anthropologist
Edward Sapir in the early 1900s to record and analyze Native American
languages.
Franz Boas: Handbook of American Indian Languages (1911
- He saw grammar as a description of how human speech in a
language is organized. A descriptive grammar should describe the
relationships of speech elements in words and sentences.
Leonard Bloomfield,
- best known for his commitment to linguistics as an independent
science and his insistence on using scientific procedures.
- His major work, Language (1933) is regarded as the classic text of
structural linguistics, also called structuralism.
Norm Chomsky
- had studied structural linguistics, was seeking a way to analyze the
syntax of English in a structural grammar.
- This effort led him to see grammar as a theory of language structure
rather than a description of actual sentences.

IC analysis


The basic concern of the descriptive approach is to investigate the
distribution of forms in a language. The method used is one of
substitution.
Constituent: a grammatical unit which is part of a larger grammatical
unit
-- e.g., sentence = noun phrase + verb phrase;
noun phrase = determiner + noun; "subject", ”verb", "determiner" and
"noun" etc. are constituents

IC analysis is designed to show how small constituents in a sentence
combine to form larger constituents.

Three aspects of a speaker’s syntactic knowledge are
explicitly represented in tree diagrams:
The linear order of the words in the sentence
- The groupings of words into syntactic categories
- The hierarchical structure of the syntactic categories
-
© BTexact Technologies 2001
Syntactic categories

A family of expressions that can substitute for one
another without loss of grammaticality is called a
syntactic category.
- The cat
chases the mouse.
- The dog
chases the mouse
- The policeman chases the mouse.
- The mother mouse
chases the mouse.
 If words and phrases could not be assigned to a
small group of categories, it would be very hard to
learn or use a language.
© BTexact Technologies 2001
Syntax: Lexical Categories

Lexical Categories:
- every word is a member of a category.
- a word’s category type determines the kind of phrase it
can form
- a phrase is a word or string of words that functions as a
unit in a sentence, built around a head
- Every language has specific phrase structure rules
determining how phrases can be combined to form
sentences
© BTexact Technologies 2001
Syntax: Lexical Categories

Noun (N):
- real, imaginary, abstract things
- In English, if nouns refer to countable things, the
regular plural is made by suffixing -s/-es
- In English they can be paired with articles and
demonstratives

-
EX: the book, this book, that book, etc.
In English they can be modified with descriptive words

Chomskyan revolution

Chomsky,
- has attracted worldwide attention with his groundbreaking research into the nature of human language
and communication.
- has become the center of a debate that transcends
formal linguistics to embrace psychology, philosophy,
and even genetics.
- his "formulation of 'transformational grammar' has
been acclaimed as one of the major achievements of
the century.
- his work has been compared to the unraveling of the
genetic code of the DNA molecule."
- his discoveries have had an impact "on everything
from the way children are taught foreign languages to
what it means when we say that we are human."
- is also an impassioned critic of American foreign
policy, especially as it affects ordinary citizens of Third
World nations.

Main features of TG Grammar
Chomsky’s TG Grammar differs from the structural grammar in a
number of ways:
-
(1) rationalism;
(2) innateness;
(3) deductive methodology;
(4) formalization;
(5) emphasis on linguistic competence;
(6) strong generative powers;
(7) emphasis on linguistic universals.

Principle and Parameter Theory


knowledge of language comprises a lexicon,
together with a set of innate principles (that
means, X-bar Theory, -Theory and Case
Theory, etc.) and set parameters.
Principle and Parameter (P&P) approach
has proved fruitful for
constraining the core of innate grammatical knowledge
(Pprinciples)
- defining the differences found between individual languages
(parameters)
- describing diachronic change (parameter resetting) and
- the investigation of first and second language acquisition
(parameter setting and resetting).

Central Claims
Language is basically simple
- The working hypothesis is that there should not be
any redundant elements in a linguistic theory and
that the computational system of language (CHL)
operates optimally.
- CHL is so designed that its outputs are naturally
‘well-formed’ and ‘economical’.

Fundamental insight about the architecture of
sentence structrure:
- Sentences do not simply consist of word strings.
Rather, within any sentence, words are grouped
together to form phrases, which then combine
with each other to form still larger phrase.
