Abstract
W. H. Walsh argued that historians used colligatory terms to describe historical change, and defined such terms as those which relate a group of events by a common idea or value. The colligatory term identifies a general relationship among singular events. Events give concrete expression to the ideas shared by the people who initiated them. Thus, colligatory terms, such as "French Revolution," are always singular proper nouns, rather than general classifications. However, in addition to common ideas, colligatory terms are used to describe the form of the historical change. Terms like "revolution" and "renaissance" do convey meaning when applied generally. Colligatory terms, then, can relate formal structures as well as dispositional. attitudes, and can function both as general classifications and as singular entities.
