The word "obsolete" is mentioned in the book "The Giver" by Lois Lowry when Jonas learns that certain things in the community are considered obsolete and are therefore no longer used or remembered, such as sledding or sunshine in the climate control. This term highlights the community's effort to eliminate anything that is deemed unnecessary or outdated.

In "The Giver" by Lois Lowry, the concept of obsolete appears throughout the book rather than on a specific page. It is a theme that relates to the suppression of individuality and emotions in the community. As the protagonist, Jonas, begins to experience memories and emotions, he questions the idea of certain things, including human emotions, being considered obsolete.
Some obsolete slang words include "groovy" (meaning cool or stylish) and "far out" (meaning extraordinary or excellent). These terms were popular in the 1960s and 1970s but are not commonly used today.
