[Title] The fate of ‹-oir(e)› in Laurentian French and the neutralization of the /ɑ/ ~ /ɔ/ opposition before /ʁ/. [Abstract] The evolution of the ‹oi› diphthong ([wε] > [wa]) is still incomplete in Laurentian French and varies according to all the dimensions of linguistic variation, as well as to the phonetic context. When the diphthong is followed by a rhotic, specific phonetic and phonological problems arise, which is why this paper will focus on ‹-oir(e)›. After a brief overview of the metalinguistic data available on this variable, we will provide a cartographic representation of its realization in traditional rural dialects, as well as some more recent geolinguistic data on contemporary Canadian French based on crowd-sourcing surveys. The second part of the paper deals with a phonological problem. The /wɑ/ diphthong has a monophonematic status in Laurentian French. For instance, while the /ɑ/ ~ /ɔ/ opposition tends to be neutralized before /ʁ/ ('part' and 'port' becoming homophones), the second element of the diphthong in a word ending in ‹-oir(e)› never becomes [ɔ] and remains [ɑ]. But the system might be changing: the analysis of a corpus of Québécois songs, as well as recent crowdsourcing surveys, suggest that [wɔʁ] for ‹-oir(e)› has now become a possible realization.
