Question: what is the tort law and economic? 

Answer: Tort law is a basic subject, usually taught to law students in their first semester of law school.  It is the major field of law in which a person can seek a remedy for an injury or loss of some sort that they have suffered outside the context of a contractual relationship.  (In a contract relationship, contract law provides most remedies.)  Tort law covers a huge range of cases, including defective products, slip-and-fall injuries, car accidents, slander and defamation, invasions of privacy, and so on.  Tort law is meant to put people who have suffered a loss or injury back in the position they were in before -- or as close as can be realistically managed.\n\n"Economic" is an adjective that usually modifies a noun, which you seem to have omitted.  When tort law tries to put a person back in their original position, it usually involves giving the injured person money to cover their costs and to compensate for things like pain and suffering.    Trying to make a person better with money means trying to figure out how much money is right, which means that economic analysis and the like are an important part of tort law.  Sadly, that means it is pretty hard to guess what your missing word might be.  You can email me at milehightaxguy@yahoo.com if you would like to clarify the question.
