Definition - What does Tortious mean?
Tortious means anything that relates to a tort. A tort is a civil wrong, as opposed to a criminal wrong. If a person believes that a tortious act was committed against them, then they can file a lawsuit. If they win, then they can collect damages or financial compensation from the tortfeasor (the one who committed the tort).
Justipedia explains Tortious
There are many different types of civil wrongs that could constitute a tortious action. For example, a person who leaves a bunch of marbles on their sidewalk and then accidentally causes a bicycle accident could have committed a tort. In such a circumstance, the bicycle rider may sue the person for damages. In order to get the damages, the bicycle rider must prove that the person caused the accident, which resulted in financial losses. If he or she can do this, then he or she may receive financial compensation.
