Usage
What is ageism? Ageism is treating people of a certain age group negatively solely because of their age, as in Thinking that all teenagers are irresponsible is ageism. Ageism is any form of discrimination against people because of their age. Most often, ageism is targeted toward older people, such as thinking that elderly people are helpless because of their advanced age. However, any age group can be discriminated against. For example, thinking that someone in their 20s is too young to be a manager is ageism. So is thinking that teenagers are irresponsible. Example: When you don’t get hired for a position you’re qualified for just because you’re older, that sounds like ageism.

Etymology
Origin of ageism
First recorded in 1965–70; age + -ism, on the model of sexism, racism, etc.
Explanation
Ageism is discriminating against someone because of how old they are. Forcing a worker to retire because they've just turned 65 is an example of ageism. Ageism, like other forms of discrimination, can take many forms. Some of these are illegal, like denying someone an apartment or a job because of their age. A boss who chooses a younger worker for a project instead of an older, more experienced employee may be guilty of ageism. Other forms of this prejudice are more subtle, like patronizing elderly people by treating them like children, or calling them "sweetheart." Ageism was coined in 1969, modeled on racism.
