UC Berkeley Phonology Lab Annual Report (2005) Expressive Alliteration in Mon and Khmer Christian DiCanio dicanio@berkeley.edu University at California, Berkeley I. Introduction: One need not look very deeply into Mon-Khmer languages to discover a plethora of expressions which are used to convey specific manners of motion, sound, feeling, and gesture. These types of descriptive words are often called expressives in the Southeast Asian linguistic literature (Diffloth, 1976). In fact, in some languages, like Semai (Aslian, Mon-Khmer; ibid), there is ample morphological, syntactic, and semantic evidence to treat these words as a separate lexical category. There also tends to be phonological evidence for the existence of expressives as a class; they tend to involve some degree of phonological repetition. 1 This is certainly the case for expressives in Khmer which are par excellence reduplicative compounds (Jacobs, 1992). While expressives are not limited in this way to repetitive structures, the reverse is indeed true; phonological repetition will almost always involve some type of expressive meaning in Mon- Khmer languages. The pattern of repetition used in expressive compounds in Mon-Khmer languages is almost exclusively reduplication with vowel ablaut, or reduplication with rime alternation. Both patterns maintain the same onset between the reduplicant and the base. Hence, I am calling all such patterns alliterative. It is usually the case that repetition is used in more descriptive speech or as a poetic device (Jacobs, 1979) in languages of the world. The use of such English expressions as dilly- dally, zig-zag, or pish-posh, is limited to more decorated speech. However, for speakers of Mon-Khmer languages, phonological repetition is a salient use of language which appears in everything from regular day-to-day speech to formal prose (ibid, Haiman & Ourn, 2001, Bauer, 1989). Whereas English has a relative handful of such words, Mon-Khmer languages have hundreds or thousands. Any serious investigation into the grammar of these languages will include an investigation of these words. Throughout the Mon-Khmer family, this process of alliteration (or reduplication) is either morphologically productive or lexicalized. In contrast to alliteration in Indo-European languages which is marginal in the grammar, alliteration is a common way that phonological repetition takes place in Mon-Khmer languages. This paper is a critical examination of the phonology, morphology, and semantics of alliterative compounds in Mon and Khmer. I will focus exclusively on compounds which have vowel alternations, which are the most common types of expressives in these languages. In a sense, this paper is exploring the many ways in which one could organize the data on alliterative compounds; i.e. by their morphology, semantics, or phonology. I have built on earlier findings by Schiller (1999) and will provide evidence in favor of the claim made by Haiman and Ourn (2001) on the morphological shape of these compounds. Specifically, alliterative compounds are unique in Mon and Khmer because they fit a 2/4 syllable prosodic template with a weak-strong pattern. In addition to other morphological characteristics, alliterating or ablauting compounds compounds in Mon and Khmer are related to the grammatical category of elaborate expressions (Matisoff, 1973) in these languages, and often denote repetitive or mimetic While the category expressive includes both onomatopoeic and other reduplicative words, it is not limited to these types.
