Movementof an X° category α is restricted to the position of ahead β that governs the maximal projection of α.(“No skipping”)11Empty Category Principle (ECP)Traces must be properly governedα properly governs β iff (i) α governs β and α is a lexical heador (ii) α antecedent-governs β.α antecedent-governs β iff(i) α c-commands βα is coindexed with β.(ii) no more than one boundingnode dominates β but not α.(iii) there is no filled C governing β.COMP-indexing: The first wh-phrase to move toSpecCP gives its index to SpecCP which canthereby antecedent govern the trace of the wh-phrase. (Wh-phrases which are subsequentlyadjoined to SpecCP will not antecedent governtheir traces).12PROTo tell if PRO is needed, consult θ-theory…(15) John tried [ PRO to leave ](16) John persuaded Bill [ PRO to leave ](17) It is difficult [ PRO to leave ](18) John is likely [ — to leave ]PRO can only appear in SpecIP of a nonfinite I.PRO does not need Case (in fact can’t get Case).Binding TheoryAnaphors: him, she, I, them, …R-expressions: Mary, the students, …Pronominals: them, him, her, …Binding. α binds β iffi) α c-commands βii) α and β are coindexed.13Binding TheoryPrinciple A: An anaphor must be bound in its binding domain.Principle B: A pronominal must be free in itsbinding domain.Principle C: An r-expression must be free.Binding domain for α:The smallest IP or DP containing α and either (a) a subject distinct from αthat does not contain α,or (b) an I assigning NOM to α.or (c) if a is a pronoun, a D assigning GEN to α.Binding Theory is about binding from A-positions. This excludes, e.g., “binding” of a wh-trace by a wh-word. They are in a c-command andcoindexation relation (a binding relation), butBinding Theory does not constrain them.14Op and the relative clauseWhere do you find Op?Op is essentially a silent which… We find it• In SpecCP of yes-no questions• In SpecCP (moved) in relative clauses.(19) CP3Op C′3CIP rG 3IjCDP I′did [+Q] Pat 3tjVP3tiV′1Vleave15(20) DP1D′3DNPthe 1N′RuN′ CP vs. which, that13N OpiC′student 3CIP[+Q] 3DPjI′John rgIVP rgtjV′3V timet16Recoverability ConditionThe content of a null category must be recoverable(from a co-indexed overt category in the sentence).Doubly Filled Comp Filter*[Comp wh-XP that/if], if wh-XP is overt (non-null).(21) Bill heard[DP the speechi [CP whichi C [IP Mary made ti ]]]."1z----------m(22) Bill heard[DP the speechi [CP Opi C [IP Mary made ti ]]]."1z----------m(23) Bill heard[DP the speechi [CP Opi that [IP Mary made ti ]]]."1z----------m17Some parameters of variation(24) U UX′ X′33XYP YPXHead-initial Head-final[SVO] [SOV]Headedness tends to be mostly uniform acrossprojections, but not invariably (German; IP, VPhead-final, CP head-initial, …)V-to-I:In French, the (finite) verb appears to theleft of negation, adverbs.
