Onset Clusters and the Sonority Sequencing Principle in Acehnese

        

Dr. Awwad Ahmad Al-Ahmadi Al-Harbi

Abstract

            This paper provides a description of Acehnese cluster phonotactics. We argue that, contrary to appearances, Acehnese syllable structure is rule-governed. The examination of the role of sonority in the construction of Acehnese complex onsets reveals that the structure of onsets is controlled by universal principles, notably by the Sonority Sequencing Principle, which holds that within an onset sonority must rise towards the syllable nucleus. It is true that Acehnese has complex clusters that do not conform to the Sonority Sequencing Principle but these clusters are created by post-cyclic syllabification rules like Stray Segment Adjunction which links stray liquids to syllable onset. We also argue that a single sonority scale characterizes sonority in all languages and that this scale subdivides the obstruents into stops vs. fricatives subclass, with fricatives being more sonorous than stops. The Acehnese data provide the strongest evidence for the well-formedness of Stop+Fricative clusters and for the role of continuancy in determining sonority distinctions.

Introduction

Sonority figures prominently in recent phonological research. It is traditionally believed that the organization of segments within the syllable and across syllables is guided by principles of sonority that rank segments from least to most sonorous. Segment sequencing in onsets, for example, is explained with reference to the Sonority Sequencing Principle, which says that, within onset, sonority must rise towards the syllable peak. The Syllable-Contact-Law (Murray and Vennemann 1983) holds that the preferred contact between sequences of adjacent but heterosyllabic segments is achieved when the coda of the first syllable is higher in sonority than that of the segment that begins the second syllable.

         Although phonologists agree on the role sonority plays in the arrangement of segments within the syllable (the most sonorous segment occupies the peak position, while the less sonorous ones are relegated towards the syllable boundary), there is a lack of agreement on its nature and a hot debate on whether sonority scales are language-specific or there is a single scale common to all languages and whether phonological principles governing syllable structure, such as the Sonority Sequencing Principle, express absolute universals or tendencies. These are some of the issues that will be the focus of our discussion when we present data from Acehnese, a language with remarkable properties.

         The striking property of Acehnese is that its sonority violations are not restricted to one end of the syllable domain. Study of many languages (such as English, Russian …etc) with syllables that offend the Sonority Sequencing Principle has led to the conclusion that a language that exhibits reversals word-initially, for example, does not usually tolerate them word-medially. When analyzing Acehnese data, it is obviously seen that complex clusters that do not conform to the Sonority Sequencing Principle occur in word-initial position as well as in word-internal position. Thus, Acehnese has a special rule allowing the offending segments to be incorporated into the syllable onset word-initially and word-internally.

         It is the purpose of this article to show that the anomalous onset clusters of Acehnese are of particular interest, however, because they are not defined in terms of position. That is, they are not restricted in their distribution to the periphery of the syllabification domain, where they do not give rise to problems of syllable division. This is what sets Acehnese apart from other languages that exhibit sonority violations.

Another distinctive property of Acehnese is that it is the only language on record whose phonotactics reveals a preference for syllables that conform to the Sonority Sequencing Principle with respect to the assumption that fricatives are more sonorous than stops. As a matter of fact, the only obstruent clusters allowed in this language are stop plus fricative sequences. This issue is important for syllable phonology because most theories of the syllable and of sonority in particular do not recognize the need for comparing these two classes of obstruents. Since the sonority scale is worked out mainly on the basis of European languages, it is clear that these two classes are basically never adjacent in any word, which makes it unnecessary to compare directly their position on the sonority scale. Consequently, the sonority scale does not include a subdivision of obstruents into stops and fricatives. This is because the range of phenomena that involves sonority does not appear to require any further subdivision of the sonority scale. Acehnese syllable structure offers evidence that such a subdivision is clearly necessary and that these clusters are well-formed with respect to the Sonority Sequencing Principle.

The implication of this phenomenon for syllabic theory is that onset clusters consisting of S+Stop are not regular onset clusters i.e. they are marked. These onset clusters constitute a major outstanding problem in current phonological theory. They violate the Sonority Sequencing Principle. But despite this fact, these types of clusters are relatively common across a significant number of languages that allow complex onsets. In this paper we propose an extension of Clements’ (1990) Dispersion Principle, an evaluation metric that determines the relative complexity of cluster types on the basis of their degree of distance from the optimal syllable and conclude that the reason why S+Stop onsets are relatively frequent across languages is because they are the least marked within the class of sonority reversals.

         The remainder of the paper is organized as follows. Section 2 gives pertinent background on the basic facts of Acehnese syllable structure. Section 3 provides theoretical background of sonority. In section 4 we discuss Acehnese onset clusters and show how they bear on current issues in sonority theory. Section 5 summarizes the most important conclusions.

2 Acehnese

Acehnese is an Austronesian language spoken by about two and a half million people in the province of Aceh, the Northern part of Sumatra, Indonesia. There are four main dialect groups; (i) Pase: Aceh Timur (langsa) and Aceh Utara (lhokseumawe), (ii) Pidie: Aceh Pidie (Sigli), (iii) Banda Aceh: Aceh Besar (Banda Aceh), and (iv) Meulabah: Aceh Barat (Meulabah). All dialects are mutually comprehensible. The main distinguishing features of the dialects are pronunciation (Pidie: caNru? ‘porridge’, Pase: cagru?) and vocabulary (Pidie: g1liju@N ‘ear’, other dialects puJu@N). It goes without saying within each major dialect there are a number of subdialects. [See Asyik (1972), (1978) and Durie (1985) for more information on different aspects of Acehnese grammar].

         The data on Acehnese presented here come from the Pidie dialect and have been elicited from four different informants; (i) Muhammad Yusran Hadi from Lemteh, Banda Aceh. Currently College of Shari’a ‘Islamic Law’ at Islamic University in Medina (his mother is Pidie and his father a Pase), (ii) Biktiyar a teacher of social sciences in an Indonesian school in Jidda, (iii) Mashhuudi a student of UKM in Malaysia, majoring in economics, and who visits Makkah to perform ‘Umrah during Ramadhan, and (iv) Sulayman Ashi, currently an employee of Umm Al-Qura University in Makkah  (All other informants are from Siglie, i.e. speak Pidie dialect).

2.2 Onsets

Onset consonants in Acehnese are obligatory. All single consonants can be syllable-initial. In addition, syllable onsets may consist of a cluster of stop or liquid plus the glottal fricative h. Also permitted are clusters of stop plus liquid.

2.3 Codas

Syllable-final consonant inventory is severely limited. The attested coda consonants are depicted in (7a) and exemplified in (7b).

 

    (7a) Acehnese syllable-final consonants

 

Stops                  p            t                     ?

                    

Fricatives                                  h

Nasals               m            n          N

           

    (7b)          rap       ‘near’             

         h1òt      ‘desire’          

         ba?       ‘tree’

         peh      ‘grind’            

         tEm  ‘tin can’         

?on   ‘leaf’              

         kVN     ‘strong’

 

         Let us close the discussion of syllable codas with an important observation. Although the palatal glide /j/ can apparently close the syllable as in (8)

 

            (8)    rhej     ‘a ruler’          

buj    ‘pig’                           

koj    ‘relatives’

 

,it best be viewed as a diphthongal offglide rather than a coda consonant. Diphthongs abound in this language.  Nothing in the following discussion hinges on this point, however.

                           

3 Sonority and the Sonority Sequencing Principle

3.1 Sonority

There has been little agreement on the question of what sonority is and how it should be defined. Phoneticians have proposed different phonetic parameters to characterize sonority. Based on acoustic intensity, Ladefoged (1993) defines sonority as the perceptual saliency or loudness of a particular sound. In Selkirk (1984), it is interpreted in terms of degree of opening; vowels are the most open, i.e. sonorous, sounds followed in decreasing order by liquids, nasals, fricatives, and stops. Multiple phonetic parameters have been proposed as well; Butt (1992) presence or absence of voicing and frictional noise; (Ohala and Kawasaki (1984) amplitude, periodicity, spectral structure, and fundamental frequency.

Phonologists, on the other hand, disagree on whether the sonority of a given segment is determined by a multi-valued feature that either makes major class features seem superfluous or eliminates them entirely from the theory of phonotactics, or whether it should be derived from major class features. While Hankamer and Aissen (1974) assign the feature sonority a range of values from 1-9 with stops near 1 end of the scale and vowels at the high end of the continuum, Selkirk (1984) assigns a sonority index to individual segments that reflects position on the sonority hierarchy. In other words, there is a single n-ary feature [sonority], which captures natural classes of segments. Kiparsky (1981) arrives at a sonority scale which is defined with reference to the major manner class features [syllabic], [consonantal], [sonorant], [nasal], and [continuant]. Clements (1990) derives sonority from the number of plus specifications for the features [syllabic], [vocoid], [approximant], and [sonorant]. Some phonologists have suggested that the relative sonority of a particular segment is formally represented in terms of geometric tree structure. In Rice (1992) the more class nodes in the tree structure, the greater the sonority of the segment in question. The liquids have two nodes in addition to the Root node, nasals have one and stops have none. In Dogil (1992) the more class nodes in the tree structure, the lesser the sonority. Thus, the segments of lowest sonority are laryngeals that consist of a laryngeal gesture. [For excellent review of phonological models of sonority, see Cser (2000)].   

3.2 Sonority scales

There are a number of competing sonority scales in the literature that rank segment types in order of their relative sonority. Views differ widely on how the sounds of speech can be arranged along a scale of sonority. The main question revolves on whether sonority ranking is language particular (9), or whether there is a single universal sonority scale that governs phonotactic patterning in all languages (10).
