1 Syntax Transformations LING 200 Spring 2003 Reading: File 6.6

2 More on movement Two kinds of syntactic rules –Phrase structure rules: generate basic structures –Transformational rules: permute or ‘move’ structures generated by phrase structure rules in limited ways prevent PS rules from becoming overly complicated can account for syntactic discontinuity

3 Model of syntax P-S rules generate:‘deep’ syntactic structure transformational rules:  ‘surface’ syntactic structure Not every sentence contains evidence of transformational rules!

4 Some transformational rules of English Subject – Aux inversion Dative shift Particle movement

5 Subject – Aux inversion NP [The student who slept through the last lecture] Aux [should be] VP [studying]. Subject – Aux inversion: S [NP Aux [X Y]  S [X NP Aux [Y Should the student who slept through the last lecture be studying?

6 Dative shift The TA gave a prize to the best student. The TA gave the best student a prize. The student left the homework assignment for their TA. The student left their TA the homework assignment. I’ll find the right size for you. I’ll find you the right size.

7 Two possible accounts of dative shift 1. Modify the PS rules: VP  V NP NP But: *The student V [put] NP [the assignment] NP [the TA’s box]. 2. Modify the output of the PS rules. The Dative Shift transformation: V NP 1 P-NP 2 V NP 2 NP 1 : V NP 1 P-NP 2  V NP 2 NP 1 :

8 Dative shift PS rules: VP V NP PP PS rules: VP  V NP PP The TA VP [ V [gave] NP [a prize] PP [ P [to]] NP [the best student]]]. V NP 1 P-NP 2 V NP 2 NP 1 Dative shift: V NP 1 P-NP 2  V NP 2 NP 1 The TA V [gave] NP [a prize] PP [to the best student]. Output:  The TA VP [ V [gave] NP [the best student] NP [a prize]].

9 Restrictions on Dative shift Dative shift transformation lexically restricted to: –bring...to, give...to, show...to, read...to,... –do...for, find...for, make...for, save...for,... –ask (a question) of Not every V NP PP: - The magician touched the girl with the wand. - *The magician touched the wand the girl. Not every V NP PP [to NP] - Paul Allen donated a million dollars to the university. - *Paul Allen donated the university a million dollars. Not every V [give] NP PP - They gave themselves up to the police. - *They gave the police themselves (up).

10 Verb - particle movement Two types of V P NP in English 1.V PP: VP [V PP [P NP]] V [look] PP [at the solution] V [rely] PP [on the help] V [wait] PP [for the next best thing] V [defer] PP [to a higher authority] V [run] PP [up the hill]

11 Phrasal verbs 2. Phrasal verb: VP [ V [V P] NP] V  V (P) (P = preposition, “particle”) V [ V [put] P [on]] NP [a coat] V [ V [put] P [off]] NP [the decision] V [ V [give] P [out]] NP [the exam] V [ V [call] P [up]] NP [the dean] V [ V [get] P [out]] NP [a pencil] V [ V [stand] P [up]] NP [a date] V [ V [run] P [up]] NP [the bill]

12 Differences between V PP, phrasal verbs 1. Position of pronominalized NP: V PPphrasal verb noun objectrun up the hillrun up the bill pronoun objectrun up itrun it up

13 Phrasal verbs and ‘particle movement’ Optional with full NP: put on a coat, put a coat on Obligatory with pronoun: *put on it, put it on run up a bill, run it up put off the decision, put it off give out the exam, give it out call up the dean, call him up

14 V PP vs. phrasal verbs 2. Entire PP can be moved to the beginning of the sentence (‘preposed’): V PPphrasal verb They said it was okay to run up the hill, and PP [up the hill] we ran. They said it was okay to [run up] V [the bill] NP, *and up the bill we ran. They said it was okay to run up the bill, and NP [quite a bill] we ran up.

15 3. Sentence fragment test:  Only a constituent can substitute for a sentence. V PP vs. phrasal verbs V PPphrasal verb Did you V [run] PP [up the hill]? No, PP [up the stairs] No, NP [the stairs] Did you V [run up] NP [the (food) bill]? *No, up the bar tab No, NP [the bar tab]

16 V PP vs. phrasal verbs 4. Separability of V, P V PPphrasal verb Stephen V [ran] stealthily PP [up a big hill]. Stephen stealthily V [ran] PP [up a big hill]. *Stephen ran stealthily up a big bill. Stephen stealthily V [ran up] NP [a big bill].

17 V PP vs. phrasal verbs 5. Possibility of coordinating PP V PPphrasal verb You have to V [run] PP [up that hill] and then PP [up an even bigger one]. You have to V [run] PP [up NP [that hill] and then NP [an even bigger one]]. *We were told not to run up the food bill or up the bar tab. We were told not to V [run up] NP [the food bill] or NP [the bar tab].

18 Summary and analysis The linear string V P NP has two possible analyses: 1.V [P NP] V + PP 2.[V P] NP phrasal verb

19 V [P NP][V P] NP PP preposingyesno PP fragmentyesno V, P separabilityyesno PP coordinationyesno

20 Position of nominal vs. pronominal objects V [P NP][V P] NP NP objectran up the hillran up the bill *ran the hill upran the bill up pronoun objectran up it*ran up it *ran it upran it up

21 Position of pronominalized NP Particle Movement (transformation) VerbP] V NP 123  132 (optional unless NP is pronoun (then obligatory))

22 Transformational vs. PS approach to Particle Movement Purely phrase structure approach VP  V (P) (NP) (run up the bill) VP  V (NP) (P) (run the bill up)

23 Drawbacks of purely PS approach doesn’t represent phrasal verbs as syntactic or lexical unit no savings in # rules needed (1 PS rule + 1 transformation) additional rule would be needed (VP  V P PP) for phrasal verb + PP: [ V [put] P [up]] PP [with the situation] [ V [let] P [up]] PP [on the pedal]

24 [V P] PP Preposing: on the pedal we let up Sentence fragment: did you let up on the pedal? No, (on) the brake. Separability: let up carefully on the pedal. Coordination: let up on the clutch and (on) the accelerator (No Particle movement: let up on it, *let on it up)

25 Summary Sentences are not just unstructured strings of words Two kinds of syntactic rules –Phrase structure rules –Transformational rules: Some transformational rules of English –Subject – Aux inversion –Dative shift –Particle movement
