noun
discrimination
dih-skrim-ih-NAY-shun/dɪˌskrɪmɪˈneɪʃn/
The making of distinctions between people or things.
The employer shows racial discrimination by rejecting an equally qualified applicant.

Etymology
The underlying 'distinction' first referred to observing or marking a difference. In the unfair-treatment sense, those distinctions are prejudicial: people are treated differently because they belong to a particular class or group.
In context
Discrimination law is specific. You have to show bias based on a protected category, meaning your age, your race, your sex, your gender, disability.
