a strategy for the expression of the semantic role of the relative clause head in the event denoted by the relative clause of an externally headed relative clause construction, in which the predicate of the relative clause uses different voice forms in order to specify the semantic role of the shared participant in the relative clause event. Example: in Luganda ekiso [John kyeyattisa enkoko] the knife with which John killed the chicken, the predicate kyeyattisa killed contains the instrumental applicative suffix -is that indicates that the relative clause head ekiso knife denotes the instrument participant in the killing event. Comrie (2003b) restricts verb-coding strategies to languages which use voice forms that are exclusively found in relative clause constructions (and thus would exclude the Luganda example); we follow the broader definition introduced in Keenan (1972).
