Introduction to LFG – 2 / 60

■ “Semantic roles, syntactic constituents, and grammaticalfunctions belong to parallel information structures of verydifferent formal character. They are related not byproof-theoretic derivation but by structuralcorrespondences, as a melody is related to the words of asong. The song is decomposable into parallel melodic andlinguistic structures, which jointly constrain the nature ofthe whole. In the same way, the sentences of humanlanguage are themselves decomposable into parallel systemsof constraints – structural, functional, semantic, andprosodic – which the whole must jointly satisfy.”Bresnan (1990)

If our theory does not include movement or other derivationalprocesses, how do we treat nonlocal relations between apredicate and its argument?

L F G Nonlocality

Introduction to LFG – 3 / 60

Nonlocal phenomena:

■ Raising: David seemed to yawn.

■ Control: David tried to catch the ball.

■ Wh-questions: Who do you think David took to the party?

How are these treated in a nontransformational, constraint-basedtheory?

L F G Raising

Introduction to LFG – 4 / 60

“Raising” verbs like seem were treated in early transformationalgrammar by raising the subject of a subordinate clause up intothe main clause (hence the term “raising”):

S

NP VP

V

seemed

S

NP

David

VP

to yawn

S

NP

David

VP

V

seemed

S

VP

to yawn

This captures the intuition that the raising verb does not assigna semantic role to the raised argument.

L F G Raising to subject

Introduction to LFG – 5 / 60

David seemed to yawn.

■ C-structure: No evidence that there is a trace or otherphrasal material in subject position in the subordinateclause.

■ F-structure: Functionally, the “raised” argument Davidbehaves as both the subject of seem and the subject of thesubordinate clause. This is functional control.

Evidence for subjecthood in matrix clause:

Evidence for subjecthood in matrix clause:

■ Verb agreement: David seems/*seem to yawn; theyseem/*seems to yawn

Evidence for subjecthood in subordinate clause:

■ Reflexivization: English reflexives are clause-bound.Davidi believed that [Janej voted for herselfj/*himselfi].

A reflexive is possible in the subordinate clause:David seemed to like himself.

Introduction to LFG – 8 / 60

David believed Chris to know the answer.

■ F-structure: Functionally, the “raised” argument Chrisbehaves as the object of believe and the subject of thesubordinate clause.

L F G Raising to object

Introduction to LFG – 10 / 60

■ Accusative case for “raised” argument:David believed him to know the answer.

■ Reflexivization: A reflexive in raised object position ispossible.David believed himself to be the best candidate.

■ Reflexivization: A reflexive in the subordinate clause canhave the raised object as its antecedent.Davidi believed Chrisj to like himself∗i,j .

Introduction to LFG – 20 / 60

Control verbs like try were treated in early transformationalgrammar by the “equi-NP deletion” transformation, and are stillsometimes called “equi” verbs:

This captures the intuition that a controlled argument gets twosemantic roles: one from the control verb, and one from thesubordinate verb.

L F G Control

Introduction to LFG – 31 / 60

Characteristics of control and raising verbs (Borjars and Vincent,2004):

■ the relation is obligatory: the control equation is introducedvia the lexical entry of the control or raising verb

■ the relation involves command (either c-command orf-command, the analogue at f-structure): the controllingverb is one clause up, and thus the controller necessarilycommands the controllee

Where are the constraints imposed? Ongoing theoretical debate:

■ Constraints are associated with position of displacedconstituent (Kaplan and Zaenen, 1989), or

■ Constraints are associated with within-clause position (a“trace”) (Bresnan, 2001).

Traces are compatible with a nontransformational,constraint-based theory, but not required by theory-internalconsiderations; linguistic evidence determines which position iscorrect. More on this later in the lecture.

L F G Weak crossover: Evidence for traces?

Introduction to LFG – 54 / 60

Most arguments for the existence of traces have been discredited.Evidence from crossover has been more difficult to refute.

Crossover in transformational terms: a transformation cannotapply if it would result in a NP “crossing over” a coreferentialNP.

Crossover in nontransformational terms, assuming traces: Thetrace of a displaced NP cannot appear to the right of acoreferential NP.

Page 80: Introduction to LFG - University of Essex · 2007-07-03 · Introduction to LFG – 2 / 60 “Semantic roles, syntactic constituents, and grammatical functions belong to parallel

L F G Weak and strong crossover

Introduction to LFG – 55 / 60

Strong crossover violation: coreferential pronoun precedes andc-commands extraction site

*Whoi did hei greet t?(cannot mean: Who greeted himself?)

Weak crossover violation: coreferential pronoun precedes butdoes not c-command extraction site

*Whoi did hisi mother greet t?(cannot mean: Whosei mother greeted himi?)

Crossover appears to provide evidence for traces: see Bresnan(1995) and Dalrymple et al. (2006) for discussion and debate.
