Summary: This study investigated the source and status of a recent sound change in Shanghainese (Wu, Sinitic) that has been attributed to language contact with Mandarin. The change involves two vowels, /e/ and /ɛ/, reported to be merged three decades ago but produced distinctly in contemporary Shanghainese. Results of two production experiments showed that speaker age, language mode (monolingual Shanghainese vs. bilingual Shanghainese-Mandarin), and crosslinguistic phonological similarity all influenced the production of these vowels. These findings provide evidence for language contact as a linguistic means of merger reversal and are consistent with the view that contact phenomena originate from cross-language interaction within the bilingual mind.
