Government&Binding Theory
� Developed by Noam Chomsky
� The descendant of Transformational
Grammar (T G)� Two levels of analysis: deep- and surface
structure
� During the 1970s two other levels:phonetic form(PF) and logical form(LF)

The "T-model"
d-structure
s-structure
phonetic form logical form(the output of the grammar (the corresponding level
at the ÅsoundÅ end) at the ÅmeaningÅ end)

The T G rule:
S(sentence)
NP (noun phrase) Aux(auxiliary) VP(verb phrase)
(modal verbs: might, could)
The node Aux is called INFL (for inflection)

Between s-structure and PF (phonetic form) the PAST element is joined with the verb and
we spell out ²ed ending on the verb:
�They PAST fire Mary.
Elements of PAST never occur in Englishas separate words.
� They fire Mary .

The Move-
� = a variable over syntactic categories� the fundamental idea: Åmoving anythinganywhereµ� questions: what can move and where it canmove?
� For example: passive moves objects
to make them subjects:
Mary was fired.

The organization of the GB grammar,with all its different components:

Syntax and Universal Grammar
� A constraint: the fundamentalgrammatical notion in GB
� It is part of the very nature oflanguage itself
The nature of UG
- The Rule R puts together elements of INFL
-The word aren·t can only appear with the s
subject I if the sentence is inverted: Aren¶t I the one? But not I aren·t the one.

X-theory (X-bar theory)� Developed in the 1970s
� Looking at the structures internal todifferent phrases:
a similar pattern: its object and thepreposition precedes its object.
X-scheme:-T he head: part of the linguistic unit that givesits essential character
(the head of an NP is the noun, the verb heads aV
P)
-The phrase is the projection of the headthe highest level of projection is calledthe maximal projection

X-scheme
X¶¶ maximal projection
specifier
(like determiners)
modifier
(for example : very)
X¶
X Argument
(constituents that a head subcategories for)

C-command and Government
Government: -a fundamental concept in GB,
-the notion of a local domain,-the same category is in the domain of
some other category.
C-command: - states a relation defined on tree-structures- a given category is hierarchically superior to.
� strong definition: c-command
iff every branching node
dominating dominates
� weaker definition: c-commands
iff every maximal projectiondominating dominates
VP
V¶ PP
V NP

Coindexing
� is used to represent many important relations
� 3 coindexing mechanism:
- Coindexing (NP,S) and AGR at d-structure
- Move- creates and preserves indices
- Freely index all A-position at s-structure

Landing sites
- Certain positions are available for movement totake place to.
- The set of possible movements:
� movement to [NP, S] postion (NP-movement)
� adjunction to COMP (wh-movement)
� adjunction to S
�adjunction to VP

Case T heoryResponsible for determining in large part thedistribution of NPs.
The basic instances of Case assignment:�If INFL contains TNS, Nominative Case
is assigned to the [NP,S]�A verb assigns Accusative Case to [NP,VP]�A preposition assigns Accusative Case
