Changes in attitude also affect language. As people become more sensitive to the rights and needs of individuals, it becomes necessary to change the words we use to describe them. The elderly are now called senior citizens. The handicapped are described as physically challenged. Many of the words show an awareness in today’s society that differences are good and that everyone deserves respect. Even the names of certain jobs have changed so that workers can be proud of what they do. The trashman is now called a sanitation worker, a doorman is an attendant, and a janitor is a custodian.
