The book LIVING LANGUAGES edited by Nancy Buffington et al.contains an essay entitled "The Invisible Discourse of the Law." A good way to introduce grammar to lawyers, I would think, would be to have them read such essays which show how sneaky and bad lawyerly language is. And to study the grammar of bad legal language. Another thought: Look at the redundancies in language ( a noun occupies a position, it has determiners in front of it, it has noun suffixes, it has plural inflections, etc.), and compare those redundancies with legal talk (assault and battery, etc.) --Bill Murdick
