n. — Politics, French relations
a member or supporter of the Bloc Québécois, a federal party devoted to Quebec sovereignty/separatism.
Type: 1. Origin — After the Charter of the French Language was passed in 1977, making French the sole official language of Quebec, many French words with no English equivalents have been borrowed into Quebec English, particularly those dealing with politics and language. Bloquiste, like Péquiste, falls under Type 1 of Boberg's (2012: 497-501) processes of lexical transfer in Quebec, which describes "elective direct lexical transfer[s]". Not surprisingly, the term is exclusively used in Canadian English (see Chart 1).
The Bloc Québécois was founded in 1991, at which time the term Bloquiste was coined (see the 1991 quotation).
