Abstract
This paper demonstrates that unexpected sound changes are best explained by an approach that accounts for
different motivations: phonetic, structural and social. Here, we focus on a multifaceted investigation of the cross-linguistically
uncommon bilabial trills to show the complex interaction between different drivers of sound change. In this paper, we highlight
and examine the prenasalized voiced bilabial trill mʙ and plain voiceless bilabial trill p [ʙ̥] found in a
number of Oceanic languages spoken on Malekula Island in Vanuatu. We offer a comparative-historical analysis, and we identify the
various forces that have led to the emergence and persistence of mʙ and p in Malekula languages: the
historical articulatory environments, the particular make-up of the consonant inventories of these languages, complementary sound
changes and phonological processes, contact with non-Austronesian languages, and in-group identity attachment. Furthermore, we
offer a hypothesis for the relative timing of these factors on the historical pathway of Malekula’s bilabial trills.
Résumé
Cet article porte sur la pluralité des motivations à l’origine des changements phonétiques, celles-ci étant
d’ordre phonétique, structurel, et social. Nous présentons ici une enquête multifacette portant sur les vibrantes bilabiales, des
sons rares dans les langues du monde, et ce afin de montrer les interactions complexes qui existent entre les différentes
motivations des changements phonétiques. Dans cet article, nous mettons en évidence et examinons la vibrante bilabiale
pré-nasalisée mʙ et la vibrante bilabiale p [ʙ̥] que l’on trouve dans un certain nombre de langues océaniennes
parlées sur l’île de Malekula au Vanuatu. Nous proposons une analyse comparative et historique et identifions les différentes
motivations qui ont conduit à l’émergence et à la persistance du mʙ et du p dans ces langues de l’île de
Malekula: les contextes articulatoires qui étaient attestés historiquement, la composition particulière des inventaires
consonantiques de ces langues, les changements phonétiques et les processus phonologiques complémentaires, le contact avec des
langues non austronésiennes, et l’attachement à l’identité ethnolinguistique. En outre, nous proposons une hypothèse pour le
parcours historique des vibrantes bilabiales du Malekula.
Zusammenfassung
Der vorliegende Artikel zeigt, dass unerwarteter Lautwandel am besten durch einen Ansatz erklärt wird, der
verschiedene Motivationen berücksichtigt: phonetische, strukturelle und soziale. Wir konzentrieren uns auf eine facettenreiche
Untersuchung des sprachübergreifend selten vorkommenden bilabialen Trills, um die komplexe Interaktion zwischen verschiedenen
Mechanismen des Lautwandels aufzuzeigen. In diesem Artikel untersuchen wir den pränasalisierten stimmhaften bilabialen Trill
mʙ und den stimmlosen bilabialen Trill p [ʙ̥], die in einer Reihe von ozeanischen Sprachen auf der Insel
Malekula in Vanuatu vorkommen. Wir stellen eine historisch-vergleichende Analyse vor und identifizieren die verschiedenen
Faktoren, die zur Entstehung und zur Beständigkeit von mʙ und p in den Sprachen Malekulas geführt haben: die
historischen artikulatorischen Umgebungen, die besondere Zusammensetzung des Konsonanteninventars dieser Sprachen, komplementärer
Lautwandel und phonologische Prozesse, der Kontakt mit nicht-austronesischen Sprachen und die Identitätsbildung innerhalb sozialer
Gruppen. Darüber hinaus stellen wir eine Hypothese für die relative zeitliche Verortung dieser Faktoren auf dem historischen Weg
der bilabialen Trills von Malekula vor.
