Reciprocal predicates: a prototype model

Many languages have verbal stems like hug and marry whose intransitive realization is interpreted as reciprocal. Previous semantic analyses of such reciprocal intransitives rely on the assumption symmetric participation. Thus, 'Sam Julia hugged' assumed to entail both hugged Julia' 'Julia Sam'. In this paper we report experimental results that go against assumption. It shown although participation likely be preferred by speakers, it not a necessary condition for accepting sentences with verbs. To analyze alternation, propose typical feature connecting meanings binary forms. This accounts optionality well preference feature. Further, our show agent intentionality often boosts acceptability Accordingly, another verbs, separate from
