The language of the law has been the object of research by many scholars for nearly century. The first publications devoted to this issue were published after the WWI, but the 21st century is a period of intense exploration of the domain from a number of angles that deserve attention. Scholars and lawyers are investigating legal language as a tool of normative communication, a method of enforcing legal order and the rule of law, and a means of observing human rights. The authors of this editorial chapter briefly scrutinize (i) the Doctrine of Flex Law within the field of Jurilinguistics, (ii) the Cross-Cultural Context of Legal Translation, (iii) the Construction of the Comparable in Jurilinguistics, and finally (iv) the Vulnerability in Legal Communication. These four axes constitute the pillars of the Edward Elgar Research Handbook on Jurilinguistics.
