Contributions of Micro-comparative Research to Language Documentation
This chapter discusses the symbiotic relationship of linguistic description and comparative research. Linguistic typology relies on detailed studies of individual languages, and grammatical description of endangered and non-endangered languages benefits from prior and concurrent study of closely related languages and the identification of parameters of similarity and difference. This view is supported by discussion of phenomena in Bantu languages, including tone and reduplication with considerable micro-parametric variation, particularly involving object markers. Two case studies are presented: (i) exceptional tonal properties of the first person singular object prefix N- and the reflexive marker di-i- in Yao, and (ii) exceptional patterns of reduplication involving /i/-initial verbs in Buguumbe Kuria which suggest a connection with the reflexive. Knowledge of analogous patterns in other languages informs the description and analysis of each language, and each case expands knowledge of the typology of patterns of exceptional object marking in Bantu languages, aiding future description of other languages.
