Louisiana French is undergoing gradual language death. In such situations, it is common to find increased variability and rapid change, as speakers use the language less often and in fewer domains (Wolfram 2004; Palosaari and Campbell 2011). These processes have been observed in the pronominal system of Louisiana French (Rottet 1996; Girard 2013), with both phonological and morphological sources of variation leading to an exceptionally large inventory of first-person-singular forms in the French of the Pointe-Au-Chien Indians of Pointe-Aux-Chênes, Louisiana. Using data from a translation task, we examine the range of forms used by French speakers from this community varying in age and fluency. We note a sharp distinction in forms used by fluent versus non-fluent speakers, with the latter making use of the non-clitic form mon. To answer the question of why mon is so common amongst non-fluent speakers in this task, we apply insights from the field of second language acquisition, considering the systems of these non-fluent speakers as autonomous and systematic. We ultimately propose a potential interaction between the previously documented phonological and morphological patterns observed in this community, influencing in the forms observed.
