The most important Principles:
The Extended Projection Principle:(EPP)
Every sentence has a syntactic subject.
The Theta Criterion:(TC)
1. Each argument is assigned only one theta role.
2. Each theta role is assigned to one argument.
The Projection Principle:(PP)
Lexical information is syntactically represented
Government: A governs B if
(i) A is the head
(ii) A and B are sisters.
C-command (C=constituent)
α c-commands β iff
(i) α does not dominate β
(ii) the first branching node that dominate α dominates β
M-command (M=maximal)
A m-commands B iff
(i) A does not dominate B
(ii) every XP that dominates A also dominates B.
Speac-head agreement
A head (X) and its specifier (Spec, XP) must agree in relevant features.
Case filter (Haegeman, 1994:167):
Every overt NP must be assigned abstract case.
Principle of structure preservation:
Movement must be structure preserving; phrasal projections (XPs) may only move to position labeled XPs.
The Binding Principles
A. An anaphor is bound in its Governing Category (GC).
B. A pronominal is free in its GC.
C. An R-expression is free.
α binds β iff
(a) α c-commands β and
The Governing Category(GC) is assumed to be IP [+TENSE, +AGR] (the finite IP)
