agreement and person in anti-agreement

many languages display correlations between subject-verb agreement and subject extraction that have come to be known as anti-agreement effects. this paper explores an anti-agreement effect found in many bantu languages whereby a third person singular human subject triggers a unique verbal agreement marker when the subject is extracted. it is argued that co-variation of certain morphological properties of constructions with subject extraction points to an agreement relation between c and t underlying the anti-agreement effect, a conclusion that converges with proposals from richards (2001) and boeckx (2003) about the nature of extraction. i also argue that although this agreement relationship involves full sets of phi-features, the differing values acquired by the feature [person] in the nominal and verbal domains often makes it appear as if [person] is uniquely affected in anti-agreement contexts.
