This paper proposes that hyperbaton in Classical Greek, Latin, and Colloquial Russian involves post-syntactic movement of prosodic constituents to prosodic edges. This conclusion is reached by way of two major observations about hyperbaton: it moves prosodic constituents (ω and φ) while ignoring syntactic constituency, and it respects prosodic constraints such as the OCP while ignoring a host of well-known syntactic constraints. This behavior is expected for PF movement, or movement in the phonological component: sensitivity to prosodic constituency and prosodic constraints and insensitivity to syntactic constituents and syntactic constraints.
