The book includes eighteen major category headings, under which the topics for each category appear in boldface type. The specific expression groups for each topic are then presented in the order in which they are found in the list of expressions. A topic number, rather than a page number, is provided at the end of each topic description, indicating where to find that topic in the list of expressions.
For instance, if you wanted to find an expression having to do with a pain in the head, you would look under the category HEALTH for a group of expressions labeled Sickness. Under sickness you would find the expression group “Describing a pain in the head 488.” Look for “Describing a pain in the head” at number 488 in the list of expressions.
