In this talk we will discuss typological tendencies of focus marking strategies from a cross-Bantu perspective. While focus-related phenomena have long been investigated in the field of comparative Bantu grammar (Hyman & Watters 1984, Güldemann 2003, Van der Wal & Hyman 2017 etc.), Shinagawa & Marten (forthc.) shed new light on some typological tendencies between focus and negation marking strategies based on the large-scale database on morphosyntactic variation of Bantu (Bantu Morphosyntactic Variation database, BMV), which is built around 142 morphosyntactic (Marten et al. 2018). Based on findings discussed in S&M, where we focused on morphological means of focus marking, we will expand the scope of investigation to integrate other types of focus marking strategies such as the CJ/DJ distinction, verb doubling construction, and syntactic positioning, in order to provide a broader picture of micro-typological correlation between focus marking strategies and other logically independent grammatical features, especially those related to morphosyntactic object a/symmetry, from a cross-Bantu perspective. The correlations we discuss in this paper help to better understand the particular position of focus marking in the grammar, defined both in functional (as seen in the relation with negation expression) and syntactic (as seen in the interaction with the syntax of objects) terms.
