Decomposing and deducing the Coordinate Structure Constraint

The article shows that the Coordinate Structure Constraint (CSC) can be violated in a number of languages and establishes a novel cross-linguistic generalization regarding languages that allow violations of the CSC. A phase-based deduction of this generalization is then provided under a particular contextual approach to phases. In addition, based on the cross-linguistic data regarding violations of the CSC, it is argued that the CSC should be separated into two conditions: (i) the ban on extraction of a conjunct, and (ii) the ban on extraction out of a conjunct. This means that the whole coordinate structure (ConjP) as well as individual conjuncts are islands independently of each other. The article also addresses the long-standing debate regarding where in the grammar the CSC applies, arguing that the two different conditions that result from the separation of the traditional CSC ((i) and (ii) above) are deduced from different mechanisms in the architecture of the grammar: one is a purely syntactic condition, and the other is an interface condition.

Probing the nature of an island constraint with a parsed corpus: A case study on the Coordinate Structure Constraint in Japanese

This paper presents a case study of the use of the NINJAL Parsed Corpus of Modern Japanese (NPCMJ) for syntactic research. NPCMJ is the first phrase structure-based treebank for Japanese that is specifically designed for application in linguistic (in addition to NLP) research. After discussing some basic methodological issues pertaining to the use of treebanks for theoretical linguistics research, we introduce our case study on the status of the Coordinate Structure Constraint (CSC) in Japanese, showing that NPCMJ enables us to easily retrieve examples that support one of the key claims of Kubota and Lee (2015): that the CSC should be viewed as a pragmatic, rather than a syntactic constraint. The corpus-based study we conducted moreover revealed a previously unnoticed tendency that was highly relevant for further clarifying the principles governing the empirical data in question. We conclude the paper by briefly discussing some further methodological issues brought up by our case study pertaining to the relationship between linguistic research and corpus development.

On Movement out of Moved Elements, Labels, and Phases

The article deduces a modified version of the traditional ban on movement out of moved elements that provides a new perspective on it. Under the proposed analysis, the problem with the movement of YP out of moved XP does not arise at the point where YP moves out of XP, as in previous accounts. Instead, it arises already with the movement of XP: XP itself cannot undergo movement in this case. Any later movement out of XP is then trivially blocked. The proposed analysis leaves room for movement out of moved elements to take place in well-defined contexts. Several constructions bear this out, including German/Dutch r-pronoun constructions, Slavic left-branch extraction, and quantifier float more generally. What the proposed analysis deduces is then not the traditional ban on movement out of moved elements, but a ban on movement of phases with nonagreeing specifiers, which the article argues should replace the former ban. As a result, the analysis also extends to the immobility of verb-second clauses in German. The article also provides a new perspective on the Adjunct Condition (the ban on movement out of adjuncts). It shows that movement out of adjuncts is possible in the same configuration as movement out of moved elements. The proposed account of the latter is then extended to the Adjunct Condition. The article also proposes a labeling-based account of the Coordinate Structure Constraint, which also captures the across-the-board-movement exception.

Coordination in Syntax

The term coordination refers to the juxtaposition of two or more conjuncts often linked by a conjunction such as and or or. The conjuncts (e.g., our friend and your teacher in Our friend and your teacher sent greetings) may be words or phrases of any type. They are a defining property of coordination, while the presence or absence of a conjunction depends on the specifics of the particular language. As a general phenomenon, coordination differs from subordination in that the conjuncts are typically symmetric in many ways: they often belong to like syntactic categories, and if nominal, each carries the same case. Additionally, if there is extraction, this must typically be out of all conjuncts in parallel, a phenomenon known as Across-the-Board extraction. Extraction of a single conjunct, or out of a single conjunct, is prohibited by the Coordinate Structure Constraint. Despite this overall symmetry, coordination does sometimes behave in an asymmetric fashion. Under certain circumstances, the conjuncts may be of unlike categories or extraction may occur out of one conjunct, but not another, thus yielding apparent violations of the Coordinate Structure Constraint. In addition, case and agreement show a wide range of complex and sometimes asymmetric behavior cross-linguistically. This tension between the symmetric and asymmetric properties of coordination is one of the reasons that coordination has remained an interesting analytical puzzle for many decades. Within the general area of coordination, a number of specific sentence types have generated much interest. One is Gapping, in which two sentences are conjoined, but material (often the verb) is missing from the middle of the second conjunct, as in Mary ate beans and John _ potatoes. Another is Right Node Raising, in which shared material from the right edge of sentential conjuncts is placed in the right periphery of the entire sentence, as in The chefs prepared __ and the customers ate __ [a very elaborately constructed dessert]. Finally, some languages have a phenomenon known as comitative coordination, in which a verb has two arguments, one morphologically plural and the other comitative (e.g., with the preposition with), but the plural argument may be understood as singular. English does not have this phenomenon, but if it did, a sentence like We went to the movies with John could be understood as John and I went to the movies.

Coherence relation and clause linkage

This paper proposes that adjunct island effects (Ross, 1967; Cattell, 1976) receive a discourse-semantic explanation. The exact formulation of this explanation builds upon previous work (e.g. Kehler, 2002) on island effects of conjuncts (Ross, 1967), which explains asymmetrical extraction from coordinate structures in English (that is, violations of the coordinate structure constraint) in terms of certain coherence relations (Hobbs, 1979). I show that asymmetric extraction from adjuncts in Chinese (that is, violations of the adjunct island constraint) is also sensitive to coherence relations. I argue that such similarities exist because coherence relations may be expressed by either a coordinative or a subordinative structure, and the variation in the syntactic realizations of coherence relations can be characterized through an independently motivated interclausal relations hierarchy that governs the mapping between semantics and syntactic linkage (van Valin, 2005).
