In Gévaudan varieties of Occitan (Gallo-Romance), exceptionless syncretism between preterite and imperfect subjunctive forms arises in the first and second person plural (e.g. faguessiám [faɡeˈsjɔn] ‘do.pret/ipf.sbjv.1pl’, faguessiatz [faɡeˈsjat] ‘do.pret/ipf.sbjv.2pl’). Reconstructing the historical emergence of this syncretism pattern reveals that it is crucially dependent on multiple and diverse implicational relationships of form, inferred and productively exploited by speakers: in particular, inherited identity between preterite and imperfect subjunctive stems, and identity between imperfect indicative forms of èstre [ɛsˈtʀe] ‘be’ and preterite or imperfect subjunctive desinences. The observed developments support a view of inflectional analogies as informed by intricate paradigmatic and implicational structure of the type proposed within ‘abstractive’, word-based theories of inflection.

This article examines early attestations of verlan and related backward slangs in French in the nineteenth century. Its main contribution is the edition and analysis of the only known text, a letter, written with features of verlan before the twentieth century. This largely predates other attested forms of verlan. The principles underlying this early form of verlan are shown to be different from contemporary verlan, as is much other early evidence, though all forms have the syllable as their basic unit. The letter is evidence that backward slangs can originate in the education system as much as in the underworld of thieves.
