如果按你给的这一小段来翻译“By duality is meant the property of having two levels of structures, such that units of the primary level are composed of elements of the secondary level and each of the two levels has its own principles of organization.”“二重性指拥有两层结构的这种特性，底层结构是上层结构的组成成分，每层都有自身的组合规则。”（莱昂斯Lyons, 1982: 20） 实际二重性在中文来说就是指事物本身所固有的互相矛盾的两种属性，即一种事物同时具有两种互相对立的性质。英语解释应该是说：Duality:Language is a system, which consists of two sets of structures, or two levels at the lower or the basic level there is a structure of sounds, which are meaningless. But the sounds of language can be grouped and regrouped into a large number of units of meaning such as morphemes and words.
