A phrase is a string of words composed of a syntactic head, its The syntactic categories we talked about so far complement (if needed), and its specifier (if any). are: NP, VP, PP, AP, AuxP, and CP. All phrases follow the X'-schema: Our grammar thus far has two types of rules: XP (i) Phrase structure rules (PSRs) of the form ru A B C, and Specifier X' (ii) Lexical insertion rules, which insert words ru into syntactic structures generated by PSRs. X Complement 7 8 Summary of Syntax so far Today’s agenda The grammar we have constructed so far It remains to account for sentence can account for the following aspects of relatedness. We do this with regard to the speakers’ syntactic knowledge: relationship between statements and - Grammaticality questions (a variation on Linda’s question - Recrusiveness from last time). - Ambiguity We also need to explain why languages differ in their syntax. We do this with regard to word order (a variation on Danielle’s question from last time). 9 10 Sentence relatedness revisited Sentence relatedness revisited As we said before, some sentences are Here’s the mini PSG again: intuitively “felt” to be related, e.g., 1. CP C AuxP a. Your friend can play the piano. 2. AuxP NP Aux' b. Can your friend play the piano? 3. Aux' Aux VP We know that a phrase structure grammar can 4. VP V (NP) (PP) generate the (a) sentence, but the question now 5. VP V (CP) is: Can it also generate the sentence in (b)? 6. VP V (AP) 7. NP (Det) N (PP) 8. PP (Deg) P NP 9. AP (Deg) A (PP) 11 12 2 Sentence relatedness revisited Sentence relatedness revisited The answer then is probably not. There is no The additional rule can help, but at a high cost: PSR that will allow the Aux “can” to appear at Now, we simply have no direct explanation for the beginning of the sentence. why a statement and a corresponding question But why should this be a problem? Can’t we are felt to be related. simply add a rule that allows us to have an Aux In essence, while a phrase structure grammar head at the beginning?

To solve this problem, we need to enrich our Can this rule help? grammar. 13 14 Transformational rules Transformational rules A solution, first proposed by Chomsky in the 1950s, is to include another What is a transformational rule? component in the grammar in addition to A transformational rule is a syntactic the phrase structure component: a operation that takes one structure as input transformational component that and operates on it producing a modified consists of a set of transformational syntactic structure as output. rules. 15 16 Deep and surface structure Deriving English yes-no questions For this purpose, a fundamental distinction in So, let’s now get back to the yes-no question the grammar has to be made between two “Can your friend play the piano?” and see how separate levels of structure: we can implement a transformational analysis. (a) a pre-transformational structure, which is Now, instead of drawing a tree for the yes-no called deep structure (or D-structure) and is question directly, we actually draw a tree for the derived by phrase structure rules, and corresponding statement “Your friend can play (b) a post-transformational structure, which is the piano.” called surface structure (or S-structure) and The only difference is that such structure will be is derived through the application of marked as interrogative. We can do that, say by transformational rules. adding a [+Q] feature on C in the tree. 17 18 3 Now, a transformation moves Aux to C, thereby deriving: Your friend can play the piano. Can your friend play the piano? CP ei CP C AuxP +Q ei eo NP Aux’ C+Q AuxP ru ei can eo Det N Aux VP NP Aux' your friend can ru ru ei V NP Det N Aux VP play ru Aux-to-C Det N Movement your friend ru the piano V NP play ru D-structure Det N the piano (Note: [+Q] indicates this sentence is interrogative. After all, we do not want to say that both sentences are identical. They obviously are not.) S-structure 19 20 Evidence for Aux-to-C movement Deriving wh-questions But how do we prove that there is actually Ok, let’s try another kind of question, the Aux-to-C movement in English yes-no so-called wh-questions, e.g., questions? What evidence is there that What will your friend play? ‘invisible triangles’ actually exist in syntax? Since “what” is interpreted as the object of Well, consider: “play,” we assume that this is where it He asked if your friend could play the piano. starts at D-structure: *He asked if could your friend play the piano. your friend will play what 21 22 Now, since this is a question, we apply Aux-to-C We apply PSRs to derive the D-structure: movement to derive the S-structure: CP CP ei ei C AuxP C AuxP +Q +Q will eo eo NP Aux' NP Aux' ru ei ru ei Det N Aux VP Det N Aux VP your friend ru your friend will ru V NP V NP play | N play | what N But does that give us the desired sentence? what 23 24 4 CP Where do wh-phrases end up? ei NP C' To get the desired surface structure, we | ei what C AuxP need to move the wh-phrase “what” to the +Q front of the sentence. will eo NP Aux' The question now is: Where does the wh- ru ei phrase move to? Det N Aux VP There is a restriction, however. It’s called your friend ru structure perseveration: Phrases can V NP move only to specifier positions, and play | heads can only move to head positions. Wh-movement t (“t” stands for trace of the moved phrase, another invisible triangle.) 25 26 A puzzle: wanna-contraction A puzzle: wanna-contraction Who do you want to kiss? Provide a principled explanation for the Who do you wanna kiss? contrast for 4 points of extra credit. Deadline: Monday Nov 12th in class. Who do you want to kiss Mary? Assume that ‘do’ starts under Aux. *Who do you wanna kiss Mary? Assume also that verbs like ‘want’ subcategorize for an AuxP complement Compare: I want to kiss Mary.

Department of Foreign Languages Kromme Nieuwegracht 29. 3512 HD Utrecht. The Netherlands [email protected] Received: December 13th 1998 Accepted: March 17th 1999 Abstract As Kayne (1994) has shown, the theory of antisymmetry of syntax also provides an explanation of a structural property of morphological complexes, the Righthand Head Rule. In this paper we show that an antisymmetry approach to the Righthand Head Rule eventually is to be preferred on empirical grounds, because it describes and explains the properties of a set of hitherto puzz- ling morphological processes —known as discontinuous affixation, circumfixation or parasyn- thesis. In considering these and a number of more standard morphological structures, we argue that one difference bearing on the proper balance between morphology and syntax should be re-ins- talled (re- with respect to Kayne), a difference between the antisymmetry of the syntax of mor- phology and the antisymmetry of the syntax of syntax proper.

  • Wh-Movement in Standard Arabic: an Optimality
    Poznań Studies in Contemporary Linguistics 46(1), 2010, pp. 1–26 © School of English, Adam Mickiewicz University, Poznań, Poland doi:10.2478/v10010-010-0001-y WH-MOVEMENT IN STANDARD ARABIC: AN OPTIMALITY-THEORETIC ACCOUNT MOUSA A. BTOOSH Al-Hussein Bin Talal University, Ma’an [email protected] ABSTRACT This paper is meant to delineate the syntax of wh-movement in Standard Arabic within the Opti- mality Theory framework. The scope of this study is limited to examine only simple, relativized and indirect verbal information questions. Further restrictions also have been placed on tense and negation in that only past tense affirmative questions are tackled here. Results show that Standard Arabic strictly adheres to the OP SPEC constraint in the matrix as well as the subordinate clauses. Findings also show that *Prep-Strand violation is intolerable in all types of information questions. Furthermore, the phonological manifestation of the com- plementizer is obligatory when the relative clause head is present or when the relative clause head is deleted and a resumptive pronoun is left behind. KEYWORDS : Wh-movement; constraints; questions; resumptive pronouns; relative clauses. 1. Introduction and review of literature Languages vary not only as to where they place wh-words or phrases, but also in the constraints governing the movement process, in general. In spite of the different kinds of movement that languages feature (topicalization, extraposition, wh-movement, heavy NP-shift, etc.), all of such syntactic phenomena do share a common property, the movement of a category from a place to another. Though its roots began long before, the unified theory of wh-movement came into being by the publication of Chomsky’s article On wh-movement in 1977.

  • Danish Pre-Nominals As Specifier Heads
    Danish Pre-nominals as Specifier Heads Anne Neville University of Southern Denmark 1. Introduction This paper presents an outline of a central aspect of an extensive formal analysis of the syntax of the Danish nominal phrase within the framework of Head-Driven Phrase Structure Grammar, cf. Pollard and Sag (1994). The aspect of the analysis I will focus on is nominal phrase structure. Modern theories of phrase structure are commonly based on X-bar Theory and phrase structure conforms to the X-bar schema proposed in Chomsky (1970). Within this tradition, there has been much discussion about the categorial status of nominal phrases. This paper is a contribution to this discussion. I propose a nominal phrase analysis which I refer to as the Specifier Head Analysis to indicate that it is a combination of the NP and DP approaches. In 2. I give some examples of Danish nominal phrases covered by the analysis. In 3. I introduce two basic assumptions that form the basis of the analysis. A brief outline of the NP and DP analyses and the difference be- tween them is given in 4. 5. is a brief introduction to HPSG. The Specifier Head Analysis is presented in 6. In 7. and 8. respectively, the analysis is applied to two types of pre-nominal, adjectives functioning as specifiers and the Danish definite article. Finally, the paper is concluded in 9. 2. Some Data In (1) examples of nominal phrases covered by the analysis are shown. The examples are by no means exhaustive. As can be seen only nominal phrases consisting of a noun and possibly pre-nominals are covered.

  • Possessive Nominal Expressions in GB: DP Vs. NP
    Possessive Nominal Expressions in GB: DP vs. NP Daniel W. Bruhn December 8, 2006 1 Introduction 1.1 Background Since Steven Abney's 1987 MIT dissertation, The English Noun Phrase in Its Sentential Aspect, the so- called DP Hypothesis has gained acceptance in the eld of Government and Binding (GB) syntax. This hypothesis proposes that a nominal expression1 is headed by a determiner that takes a noun phrase as its complement. The preexisting NP Hypothesis, on the other hand, diagrams nominal expressions as headed by nouns, sometimes taking a determiner phrase as a specier.2 This basic dierence is illustrated in the following trees for the nominal expression the dog: NP DP DP N0 D0 D0 N0 D0 NP dog the D0 N0 the N0 dog The number of dierent types of nominal expressions that could serve as the basis for an NP vs. DP Hypothesis comparison is naturally quite large, and to address every one would be quite a feat for this squib. I have therefore chosen to concentrate on possessive nominal expressions because they exhibit a certain array of properties that pose challenges for both hypotheses, and will present these according to the following structure: Section 2.1 (Possessive) nominals posing no problem for either hypothesis Section 2.2 Problem nominals for the NP Hypothesis Section 2.3 How the DP Hypothesis accounts for the problem nominals of the NP Hypothesis Section 2.4 Problem nominals for the DP Hypothesis Section 2.5 How the NP Hypothesis accounts for the problem nominals of the DP Hypothesis By problem nominals, I mean those which expose some weakeness in the ability of either hypothesis to: 1.

  • The Asymmetry and Antisymmetry of Syntax¹ a Relational Approach to Displacement
    The Asymmetry and Antisymmetry of Syntax¹ A Relational Approach to Displacement Justin Malčić 2019 Part IIB Dissertation Linguistics Tripos University of Cambridge 9,963 words ¹Special thanks go to Theresa Biberauer for her invaluable comments and support while supervising this dissertation. Any remaining errors are my own. Abstract In both syntax and phonology, it has long been observed that significant restrictions exist on displacement. One such restriction ensures that displacement leads to sequences of elements which are in some sense contiguous, formalised in syntax in the concept of Feature Geometry-based Relativised Minimality by Starke (2001) and Contiguous Agree by Nevins (2007), and in Autosegmental Phonology by the Line-Crossing Prohibition (originating in the Well-formedness Condition in Goldsmith 1976). I argue that effects of this type, which have been called Contiguity Effects, are best captured by taking displacement to involve total weak orders of elements in the sense of Order Theory. Building on work taking the LCA to hold throughout the derivation, I argue that precedence relations may be the basis of phrase structure, though without claiming that linearisation is necessary for LF (as for example suggested in Kayne 2013). I then develop this approach to show that Order Theory provides useful axioms for both phrase structure and displacement, and that the existence of displacement is expected given the use of Order Theory. 2 The extent of ‘antisymmetry’ in syntax has been a major issue for phrase structure theories ever since Kayne’s (1994) original proposal for the Linear Correspondence Axiom. The requirement for antisymmetry in linearisation seems to follow from the nature of the phonological component, which seems to show a different kind of recursion to that displayed in syntax.
