A model of grammar closely related to transformational grammar and originating from work described by Fillmore. Case Grammar attempts to characterise the set of semantic roles, called cases, that a noun phrase may fill. In Fillmore's paper, six cases were introduced, and each noun phrase must fill exactly one. Fillmore's cases are agentive, instrumental, dative, factive, locative and objective. The main notion that Case Grammar attempts to capture is that in comparing sentences like John read the book and This book reads easily the subject of the first sentence (John) is the agent (John is reading the book), whereas the subject of the second (This book) is the object (the book is being read).
