Addressing questions of grammaticalization in creoles

Claims about grammaticalization in creole languages are often made without applying empirical tests. For Palenquero Creole, the habitual morpheme asé bears formal resemblance to Spanish hacer ‘do’, providing easy fodder for provenance theorists. While the origins of asé have been debated for decades, we have no studies. In the present study, claims made by scholars were converted into testable hypotheses which make specific synchronic predications regarding asé’s functions and distributions relative to attested cross-linguistic trends in the development of tense and aspect expressions. Rigorous tests or ‘grammaticalization indices’ were then applied in order to determine asé’s degree of conformity. The results of multivariate analysis revealed that asé is walking a tightrope of being an emerging yet advancing grammatical morpheme, although not obligatory. I stress that it was only through the application of accountable data mining and analytical procedures that we could build a solid case for grammaticalization of asé habitual.
