Reciprocal constructions involve a complex mapping of semantics onto morphosyntax, requiring multiple propositions to be overlaid onto a single clause and the permutation of semantic roles within the set of participants involved. This complexity challenges the standard processes relating predicates to situations, and thus languages arrive at a great diversity of solutions for how reciprocal situations are encoded within a single clausal structure. Recent typological work has showcased this diversity from different perspectives, but further work is needed to determine how different morphosyntactic and semantic properties interact and what implicational connections and correlations exist with other parts of the linguistic system. Theoretical typologies highlight the importance of reciprocal constructions for our understanding of grammatical structure crosslinguistically.
