When a reflexive argument is bound by a local subject (Local Subject-Oriented Reflexivity, LSOR), many languages employ a distinct morphosyntactic configuration for marking reflexivity, including: Dogrib (Na-Dené) ede, Italian (Romance) si, Japanese (Altaic) zibunzisin, Kannada (Dravidian) -koND, Russian (Slavic) sebe, and Shona (Niger-Congo) zvi.
This raises an important and naive question: what is it about local subjects that gives them a privileged ability to license LSOR-marking? Upon further investigation, a second more informed question arises: why do only some local subjects (specifically, non-derived subjects) license LSOR-marking?
I argue that reflexive anaphors move to a position near the subject, and this movement is done to locally satisfy the syntactic and semantic demands of a reflexive Voice0, REFL, which ensures (without stipulation) that the subject is not a derived one. With only REFL, its syntactic/semantic properties, and constraints on locality, we thus derive how the grammatical role of the antecedent may effect LSOR-marking.
Additionally, this analysis derives the range of possibilities for morphosyntactic exponents of LSOR: including a unique anaphor, verbal affix, and/or special word-order. Specifically, REFL Voice0 can be realized (or not), it induces a (covert) movement that can result in a special word-order (or not), and anything it selects (including an anaphor) can be featurally-distinct and can thus have a unique form (or not). These are all purely instances of surface variation with the same formal underpinnings.
As such, the subject-orientation puzzles presented by LSOR, as well as its possible morphosyntactic instantiations, are reduced to issues of locality and surface variation.
