Assess graduate students' recall of key terms, core models, and seminal authors in lexical semantics: define and distinguish polysemy vs. homonymy; summarize prototype theory (e.g., Rosch, Lakoff); list principal sense relations (synonymy, antonymy, hyponymy, meronymy); and identify major approaches to semantic roles (thematic roles, case grammar, frame semantics) with associated authors (Cruse, Pustejovsky, Fillmore, Jackendoff). Focus is on accurate identification and attribution; brief recall only.
