A civil wrong, other than breach of contract, for which a remedy may be obtained, usually in the form of damages; a breach of a duty that the law imposes on persons who stand in a particular relation to one another.

In Plain English:

A tort has happened when one person has harmed another person but is not a crime. The person who was injured then has the ability to seek compensation for the injuries they suffered by filing a law suit against the person who caused the damages and injuries.
