Proto-Properties and Grammatical Encoding develops a comprehensive proto-property theory of argument encoding based on the work of David Dowty. Such a theory is intended to cover much of the empirical ground of mapping/linking theories in identifying the principles of correspondence between the lexical semantics of predicators and the relational and case encodings of their arguments. In this theory, Farrell Ackerman and John Moore identify two basic strategies for the organization of lexical information and demonstrate how these two strategies yield widespread patterns of regularity in the lexical information associated with predicators cross-linguistically. In particular, they consider the psych predicates, causatives, so-called dative subjects, and object encoding in Finnic.
