Page 3: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

1. Introduction

(1) About what will I talk?(2) What will I talk about?

(1) displacement of P about (“pied-piping”) (2) P about “in-situ” without complement (“stranded”)

Page 4: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

1. Introduction

Preposition stranding as in (2) looks like normal long-distance filler-slot structure, but:

Not all languages allow P stranding, cf. e.g.:

(3) *Das Thema, das ich über sprechen werde(4) The topic which I will talked about

Which factors affect P stranding/pied-piping in E?

Can all stranded data be captured by a general construction/constraint? [which e.g. licenses SLASH-ed COMP-lists for P]

Page 5: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

2. Stranding and Pied-Piping in English

In English stranding occurs in four structures

in which …:

i. Strandingi I’ve heard ofi. [preposing]

ii. Whati is he talking abouti? [open interrogative]

iii. What a great topici he talked abouti! [exclamative]

iv. the structure [whichi he talked abouti]. [wh-relative]

(cf. Pullum and Huddleston 2002: 627)

Page 6: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

2. Stranding and Pied-Piping in English

In English stranding occurs in four structures

in which pied piping is an alternative option:

i. Of strandingi I’ve heardi. [preposing]

ii. About whati is he talkingi? [open interrogative]

iii. About what a great topici he talkedi! [exclamative]

iv. the structure [about whichi he talkedi ]. [wh-relative]

(cf. Pullum and Huddleston 2002: 627)

Page 7: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

2. Stranding and Pied-Piping in English

In English stranding occurs in four structures

in which pied piping is not possible:

v. the structure [(thati) he talked abouti]. [non-wh relative]

vi. the same stuffi as [I talked abouti]. [comparative]

vii. His talki was easy [to find fault withi]. [hollow clause]

viii. Strandingi has been talked abouti enough]. [passive]

(cf. Pullum and Huddleston 2002: 627)

3. Roadmap: What to Expect

1. P placement across clause types (corpus)

2. Categorical RC data (corpus)

3. Magnitude Estimation experiments

4. Variable RC data (corpus)

5. Conclusion

Page 9: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

4. Corpus Data

• Corpus used:

International Corpus of English ICE-GB (educated Present-day BE, written & spoken)

(tagged for Pstranded / parsed “P+Wh“ search)

• Analysis tool:

GOLDVARB computer programme (logistic regression; Robinson et al. 2001) relative influence of various contextual factors (weights: <0.5 = inhibiting factors; >0.5 = favouring)

Page 10: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

Pstrand/pied-piped token tested for

1. Clause Type

2. displaced element (who, what, NP, etc.)

3. XP contained in (V / N, e.g. entrance to sth. / Adj, e.g. afraid of sth.)

4. level of formality

5. X-PP relationship (Vprepositional, PPLoc_Adjunct, PPMan_Adjunct …)

(e.g. Bergh, G. & A. Seppänen. 2000; Hoffmann 2005; Trotta 2000)

4. P placement across clause types

Gries 2002: P placement affected by

1) processing effort

2) prescriptive grammar rules

Yes, but also:

3) idiosyncratic combination of both!

4.2 Variable stranding contexts:

Page 28: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

processing:stranding more complex than pied piping since

1) Hawkins 2004: potential processing problems

(11) Whoi did John see*i Bill talk toi

(12) To whomi did John see Bill talki

2) Stranding defers filler-gap identification beyond verbal head of clause

4.2 Variable stranding contexts:

Page 29: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

“Gap sites and nodes containing them that are predictable on the basis of conventionalized co-occurrence of their subcategorizers are easier to process than adjunct gaps and adjunct clauses.” (Hawkins 2004: 213)

4.2 Variable stranding contexts:

Page 30: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

“Gap sites and nodes containing them that are predictable on the basis of conventionalized co-occurrence of their subcategorizers are easier to process than adjunct gaps and adjunct clauses.” (Hawkins 2004: 213)

explains effect of factors in PP type:• lexically specified PPs favour stranding• stranding with adjunct PP: semantic factors

(cf. below)

4.2 Variable stranding contexts:

Page 31: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

In languages that have filler-gap structures for both relative clauses and wh-questions, if a gap is grammatical for a relative clause filler in an FGD of complexity n, then a gap will be grammatical for a wh-question filler in an FGD of complexity n. (Hawkins 2004: 200)

4.2 Variable stranding contexts:

Page 32: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

In languages that have filler-gap structures for both relative clauses and wh-questions, if a gap is grammatical for a relative clause filler in an FGD of complexity n, then a gap will be grammatical for a wh-question filler in an FGD of complexity n. (Hawkins 2004: 200)

partly explains effect of Clause*Formal:

• Free-RC/Q less complex than RC favour Pstrand

• yet: level of formality interaction effect?

4.2 Variable stranding contexts:

Page 33: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

Note: if only processing effect

only need for one general Pstrand construction

Yet: level of formality only associated with Cleft-/WH-RCs

!require extra Pstrand and Ppiped constructions

for these clause types!

4.2 Variable stranding contexts:

Page 34: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

As the ICE-GB data showed both stranding and pied piping occur mostly in relative clauses

closer look at RC data

[further constraints beyond formality?]

5. Corpus Study II: Relative clauses

all that/Ø-tokens in ICE-GB stranded

ICE-GB result: expected

implications: (2) = (3)? / that WH-

5. Corpus Study II: Relative clauses

Page 36: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

2. X-PP relationship:

ICE-data showed: difference between adjunct PPs

claim:

Pstranding restricted to PPs which add thematic information to predicates/events

= processing constraint: allows integration of P within VP

5. Corpus Study II: Relative clauses

Page 37: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

2. X-PP relationship:

Categorical effect of non-θ-WH-PPAdjuncts-tokens:

a) just P+WH / no that/Ø+P in ICE-GB: e.g. manner adjunct PPs:

(12) a. the ways in which the satire is achieved <ICE-GB:S1B-014 #5:1:A>

b. the ways which/that/Ø the satire is achieved in

5. Corpus Study II: Relative clauses

Page 38: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

2. X-PP relationship:

Categorical effect of θ-WH-PPAdjuncts-tokens:

b) just P+WH / but that/Ø+P in ICE-GB: e.g. locative PP adjuncts

(13) a. … the world that I was working in and studying in

<ICE-GB:S1A-001 #35:1B>

b. … the world in which I was working and studying

5. Corpus Study II: Relative clauses

Page 39: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

Claim: comparison of WH- vs that/Ø shows:

P can only be stranded if: PP adds thematic information to predicates/events[= can be semantically integrated by head of RC]

e.g.: manner & degree adjuncts:compare events “to other possible events of V-ing” (Ernst 2002: 59)

don’t add thematic participant Pstrand with these: systematic gap

5. Corpus Study II: Relative clauses

Page 40: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

Claim: comparison of WH- vs that/Ø shows:

P can only be stranded if: PP adds thematic information to predicates/events[= can be semantically integrated by head of RC]

In addition to PP-types and Formality effects, variable corpus data (450 finite WH-token)exhibited two more effects (Hoffmann fc.):

1. NP-contained PPs favour pied piping 0.964

2. restrictive RC favour pied piping: (weight: 0.592) nonrestrictive RC clearly inhibit pied piping

(i.e. favour stranding; weight: 0.248)

(Model: Fit:X-square: p = 0,5610 / R2 = 0,92 / multiple adjusted R2 = 0,90 / Cross-validation estimate of accuracy = 0.916)

Page 56: Preposition Stranding in British English: ?Up with how much constraints do you have to put?

Note: both processing effects

1. NP-contained PPs favour pied piping:

NP itself contained in VP: Pstrand complexity[cf. also Cowart 1997]

2. nonrestrictive RC favour stranding: filler-gap identification process in non-restrictive relative clauses less complex than in restrictive relative clauses (Hawkins 2004: 240ff.)
