A civil right is a right created by the government. The right to free speech is a good example of a civil right in the United States. Free speech is guaranteed by the First Amendment of the United States Constitution. Because this right is created by the federal government, it is a "civil right". If you have truly been denied free speech, you have been denied a civil right.
In the legal language today, the group of rights that are commonly referred to as "civil rights" relate to the protections against race, religion, age, gender, or national origin discrimination. If you have been discriminated against because of one of these categories, you may have a civil rights case.
Can I Sue?
To be able to sue for a violation of your civil rights, generally, you must have suffered an injury. A civil rights injury does not need to be a physical injury. Injuries that result from racial stigmatization should allow you to sue for a legal remedy. Injury that stems from your illegal arrest can be vidicated by a civil rights damages award. These are but two examples.
