Semantic Roles
As noted before semantie roles were introduced as a way of classifying the arguments of pred- d icators (mostly verbs and adjectives) into a closed set of participant types. Even though we cannot make any absolute generalizations about the relationship between grammatical func- tions and semantic roles, the properties of semantic roles do interact regular ways with cer- in tain grammatical constructions. A list of the most relevant thematic roles and their associated properties is given below.
