The syntactic structure of predicatives : clues from the omission of the copula in child english
(2001)
This paper explores the syntax of main clause predicatives from the perspective of trying to account for an asymmetry in copular constructions in certain languages. One of the languages in which we find such an asymmetry is child English (around age 2). Specifically, new results show that children acquiring English tend to use an overt (and inflected) copula in individual-level predicatives, but they tend to omit the copula in stage-level predicatives. The analysis adopted to account for this pattern draws on evidence from adult English, Russian, Spanish and Portuguese that stage-level predicates are Aspectual (they contain AspP) while individual-level predicates are not (they involve only a lexical Small Clause predicate). Children's omission of the copula in structures with AspP is linked to the fact that at this stage of development, children fail to require finiteness in main clauses. In particular, Asp0 is temporally anchored in child English, thereby obviating the need for a finite (temporally anchored) Infl, i.e. an inflected copula.
The ultimate goal of this paper is to find a representation of modality compatible with some basic conditions on the syntax-semantic interface. Such conditions are anchored, for instance, in Chomsky's (1995) principle of full interpretation (FI). Abstract interpretation of modality is, however - be it "only" in semantic terms - already a hard nut to crack, way too vast to be dealt with in any comprehensive way here. What is pursued instead is a case-study-centered analysis. The case in point are the English modals (EM) viewed in their development through time - a locus classicus for a number of linguistic theories and frameworks. The idea will be to start out from two lines of research - continuous grammaticalization vs. cataclysmic change - and to explain some of their incongruities. The first non-trivial point here consists in deriving more fundamental questions from this research. The second, possibly even less trivial one consists in answering them. Specifically, I will argue that regardless of the actual numerical rate of change, there is an underlying and more structured way to account for the notions of change and continuity within the modal system, respectively.
Chunk parsing has focused on the recognition of partial constituent structures at the level of individual chunks. Little attention has been paid to the question of how such partial analyses can be combined into larger structures for complete utterances. Such larger structures are not only desirable for a deeper syntactic analysis. They also constitute a necessary prerequisite for assigning function-argument structure. The present paper offers a similaritybased algorithm for assigning functional labels such as subject, object, head, complement, etc. to complete syntactic structures on the basis of prechunked input. The evaluation of the algorithm has concentrated on measuring the quality of functional labels. It was performed on a German and an English treebank using two different annotation schemes at the level of function argument structure. The results of 89.73% correct functional labels for German and 90.40%for English validate the general approach.
A contrast to a trace
(2001)
For movement, such as quantifier raising, the three different structures illustrated in (1) are discussed in the recent literature.
(1) A girl danced with every boy
a. [every boy]x a girl danced with x (copy + replace)
b. [every boy]x a girl danced with [every boy] (copy)
c. [every boy]x a girl danced with [thex boy] (copy + modify)
In this paper, I'll call the proposal illustrated by (1a) the copy+replace theory since the movement is analyzed as first copying the moving phrase followed by replacing the moving phrase with a trace in the base position of movement. Chomsky (1993) and Fox (1999) argue against the copy+replace theory (1a) on the basis of Condition C data that show that moved material can behave as if it occupied the base position of movement. This behavior would, for example, be expected on the copy theory of movement illustrated by (1b), which also seems conceptually simpler than the copy+replace theory since it involves only copying without replacement. This conceptual advantage, however, is probably only apparent since a theory of the interpretation of structures like (1b) would probably be more complicated than for (1a). Standard assumptions about interpretation, at least, don't predict the right meaning when applied to (1b). For this reason, Chomsky and Fox propose what I'll call the copy+modify-theory illustrated in (1c). This proposes that copying is followed by a trace modification operation that replaces the determiner of the moved DP with something else. I assume that this is an indexed definite determiner, the interpretation of which is to be clarified below.
