The syntax of African American English borrowings in the Louisiana Creole tense-mood-aspect system

This paper presents the typologically unusual case of borrowed tense-mood-aspect morphemes. Data are taken from Louisiana Creole, a critically endangered French-lexifier creole. Over the course of its history, Louisiana Creole has been in contact with local varieties of both French and English, including African American English. It will be shown that points of structural congruity between Louisiana Creole and African American English have facilitated the borrowing of two aspect markers for speakers competent in both varieties. African American English stressed BIN has been borrowed and marks remote past habitual, stative, and completive. The adverb still has been borrowed and subsequently has grammaticalized as a continuative marker via spec-to-head reanalysis. These borrowings are integrated into the inflectional domain as functional heads marking aspect. Their ordering constraints are evaluated relative to a previous hierarchy proposed by Rottet. Discussion of contact-induced change in creole languages has typically been confined to examination of interactions with the lexifier, the language which contributes the majority of a creole’s vocabulary (in this case, French). Fewer studies have presented detailed accounts of how creoles behave when in contact with other languages, meaning that this particular contact context remains undertheorized.
