Abstract: The relationship between the law and language has become an important subject in the studies of law currently when the rule of law in society has been gradually improved. The law and the language rely on each other，legal quality being defined and clarified by language. However，with its defects，language inevitably blurs the accuracy of the legal terms. From the perspective of frontier sciences，law and language are inseparable as language is the vehicle for law and is shaped by law to a certain extent. Such studies of law and language will contribute to the more appropriate application of law.

Key words: frontier science, law, language, application of law, legal terms
