This article examines the adaptation of the French rhotic in Berber. In loanwords borrowed from French, the uvular fricative is systematically interpreted as a coronal tap, despite the fact that Berber has phonemic /ʁ/ and /χ/. It is argued that this phenomenon is determined by phonological rather than phonetic factors. It is shown that Tashlhiyt Berber speakers, including monolinguals, are able to identify the French r as a sonorant, based on their native phonology, where many co-occurrence restrictions are analyzed in terms of sonority-sensitive dependency relations between the most sonorous segment and its neighboring segments.
