语言符号的任意性和偶然性有一些共同之处,如它们都体现了社会规约的力量、都造成语言的可变性和多样性。然而,它们更有着明显的区别,如它们与象似性的关系不同、它们的反面概念不同、它们的地位不同。所以,不能把它们当成同一概念。 The arbitrariness and contingency of linguistic signs have something in common, as they both embody the power of social norms and cause the variability and diversity of languages. However, there are even more obvious differences between them. For example, they differ from iconicity in that their opposite concepts are different and their status is different. Therefore, you can not treat them as one and the same concept.
