The Representation of Features and Relations in Non-linear Phonology
, E. C. Sagey 1986
In this thesis, I propose the following hierarchical representation for the distinctive features of phonology.
root
continuant
consonantal
laryngeal
supralaryngeal
constr. glottis
spread glottis soft palate place
stiff v.c.
slack v.c. nasal labial coronal dorsal
round anterior high low back
distributed
This hierarchy is based on phonetics: Features are grouped according to the articulator in the vocal tract that they are executed by. Articulators are grouped according to their acoustic effects on the formant structure.
The hierarchy, which is proposed to be universal, allows a straightforward account of the complex phenomena that surround multiply-articulated segments, such as labiovelars, labiocoronals, coronovelars (e.g. clicks), and labialized, palatalized, or velarized consonants. This type of segment, with unordered or simultaneous multiple articulations, I refer to as a complex segment. The theory of representation I propose makes it possible to represent all the complex segments that occur, and provides an explanation of why those complex segments that occur are possible in a language, as well as of why those that do not occur are impossible. Furthermore, it makes possible an account of the derivation of complex segments, where they are derived, and of their behavior with respect to phonological processes. In addition, the proposed theory of representation is shown to account for unrelated phenomena in languages without complex segments, which provides independent support and shows that the representation is universal, rather than particular to complex segment languages.
In Chapters 1 and 2, I argue for the hierarchical feature groupings shown above. (The root, laryngeal, supralaryngeal, and place constituents were proposed by Mohanan (1983) and Clements (1985).) I demonstrate that the only complex segments that occur are those combining two or more of the hierarchical constituents: labial, coronal, dorsal. I argue, based on timing, syllabification, reduplication, compensatory lengthening, prenasalization, and nasal assimilation, that complex segments occupy single x-slots, and furthermore that the multiple articulations in complex segments must be represented within a single place node. Complex segments are contrasted with contour segments, in that the latter involve sequences of articulations within a single segment " a distinction which determines the different behavior of complex and contour segments with respect to phonological rules. Furthermore, I show that the structure within the place node required by complex segments finds independent support in languages without complex segments. For example, the structure allows us to account for patterns of blocking and transparency in harmony systems. Thus, the structure within the place node is a universal property of the representation of distinctive features, rather than just a peculiarity of complex-segment languages.
In Chapter 3, I propose a mechanism for assigning the degree of closure features [continuant, consonantal] to the articulators that execute them. This representation of degree of closure features is necessary in order to account for the behaviors of complex segments, and furthermore allows degree of closure in complex segments to be represented identiically to that in simple segments. The modifications of the feature representation that are necessary to represent and account for the behavior of complex segments lead to a concise characterization of the possible complex segments in human language.
In Chapter 4, I redefine the distinctive features (i.e. the terminal nodes in the hierarchy) in light of the proposal made in Chapters 1, 2, and 3, and I define the non-terminal nodes in the hierarchy.
Chapter 5 contains a further demonstration of the possibility of explaining phonology in terms of external factors. I demonstrate that the association lines among features and x-slots that connect all the tiers in the hierarchy must represent the relation of overlap in time, and I show that when they are correctly defined as representing overlap, the ill-formedness of crossing association lines follows from the relations represented in a phonological representation, together with knowledge of the world, and need not be stipulated as well-formedness condition in UG.
Finally, in Chapter 6, I discuss two aspects of phonetic representation that are made possible by the view of phonological representations taken in Chapters 1 through 5 " degrees of closure of individual articulators and subsegmental timing.
