法律语言是法学和语言学交叉的一门边缘学科。法律，作为法律语言所要表述的内容，无论是立法还是司法都要求准确；语言，作为法律赖以进行表述的形式，无论是口头还是书面，都同样要求准确。所以，法律语言，准确为要，准确是法律语言的生命。本文从立法、司法两方面论述了这一问题。 Legal language is an interdisciplinary branch of law and linguistics. Law, the content to be expressed as a legal language, requires accuracy both in legislation and in the judiciary. Language, as a form of expression by law, both verbally and in writing, also requires accuracy. Therefore, the legal language, accurate to be accurate is the life of the legal language. This article discusses this issue from the aspects of legislation and judicature.
