Prosodic Adaptation of Egyptian Arabic Loanwords from English Elijah Reynolds Indiana University Abstract The present study provides an analysis for two types of prosodic adaptations in Egyptian Arabic loanwords from English: a phonological repair strategy that augments the moraic representation in underweight monosyllable loanwords, and a perceptual adaptation that preserves stress acoustic cues of stress on the source syllable. Following Kiparsky’s (2003) analysis of Egyptian Arabic (EA) syllable structure, word-final C is extrametrical. However, a minimal word constraint in EA requires monosyllabic words to be bimoraic. Thus, the minimal word constraint motivates CV<C> words to undergo final C gemination to CVG as a phonological repair afforded by the underlying moraic representation of geminates (Davis, 1999). Geminates in EA loanwords from English occur predominately in word-final consonants in CV<C>. Vowel lengthening, on the other hand, occurs frequently – and almost exclusively – in polysyllabic adaptations to preserve the stress pattern of the source form. The motivation for an analysis of EA loanword adaptations is that it provides us with empirical data of “constraints that cannot be motivated by native language alternations because the relevant structural types do not occur in the native vocabulary”, (Broselow, 2006). A major debate in loanword phonology is the question of a perceptual vs. phonological grammar. The present paper demarcates the effects of perceptual mapping (Steriade, 2002) of syllable prominence (i.e. stress) from the abstracted phonological processes (Silverman, 1992) of gemination in underweight from English to EA. Stress adaptation and moraic adaptation in CCVC source forms have similar effects, but they are motivated from two distinct modules: a perception grammar initiates the adaptation of stress, and a production grammar constrains the moraic representation at the phonological interface, resulting in variant adaptation patterns. During adaptation from English /grup/ ‘group to EA /gurubb/, adaptation must negotiate between faithfulness to the source stress, and markedness stipulated by the prosodic constraints of EA militating against the onset cluster and the underweight (monomoraic) word in /*grub/. Neither geminates, nor long vowels are a part of English phonology. The observation of gemination and vowel-lengthening in EA loan adaptation is based on a subset of 200 EA loanwords from English, roughly 85 of which undergo V-lengthening and 25 geminate the final consonant. The preference for geminates in loan adaptation of CVC words is interpreted as the result of a production-grammar constraint on the phonological module, while V-lengthening in resyllabified CvCV:C words is an effect of the perceptual extraction of stress cues in the acoustic signal which are converted to length in an interpretation-by-synthesis design, (Calabrese, 2009).
