A Late-Insertion-Based Exoskeletal Approach to the Hybrid Nature of Functional Features in Creole Languages

The goal of this paper is to further our understanding of the nature of functional features in Creoles while focusing on how the functional exponent is morphologically realized, assuming a late-insertion-based exoskeletal model in the language mixing scholarly literature. In language mixing, it is observed that words are mixed within a certain syntactic domain (e.g., DP-NP, VoiceP/vP-TP, etc.). For example, in the nominal domain, a determiner D may be from one language, and N (or a stem, e.g., root + categorizer) may originate from another language. Grimstad and Riksem propose that the functional projection FP intervenes between D and N, and both D and F are from one language and N from another language. The phonological exponent of the functional features (e.g., D and F) are assumed to be language-specific (i.e., from one language), subject to the subset principle. Closer to the case that concerns us, angstrom farli and Subbarao show that through long-term language contact, functional features can be reconstituted, and the functional exponent can be genuinely innovative. In our study, we propose that functional features can be themselves recombined and that Creole languages can provide evidence for feature recombination either by virtue of their hybrid grammar or through the congruent functional categories they display, using a late-insertion-based exoskeletal model. That is, functional features are not individually inherited from one language or another but can be recombined to form new functional features, allowing a novel functional exponent. To show this, we use synchronic empirical data focusing on the anterior marker -ba from Cabo Verdean Creole (CVC), Manjako (one of CVC Mande substrates), and Portuguese (CVC lexifier) to show how the recombination may operate, as CVC -ba recombines the features it inherited from its source languages while innovating. In sum, the purpose of this study is to show that feature recombination targeting the functional categories of Creole source languages can lead to innovation and that a late-insertion exoskeletal model can best account for the novel functional exponents that result from feature recombination in Creole formation.
