Penology (from "penal", Latin poena, "punishment" and the Greek suffix -logia, "study of") , the term has probably been coined by Francis Lieber, is a section of criminology that deals with the philosophy and practice of various societies in their attempts to repress criminal activities, and satisfy public opinion via an appropriate treatment regime for persons convicted of criminal offences. The Oxford English Dictionary defines penology as "the study of the punishment of crime and prison management," and in this sense it is equivalent with corrections.
