the relationship between the form of a sign, such as a word or symbol, and its meaning

Iconicity is central to the study of literary uses of language, such as prose and poetry. 象似性对研究语言的文学用途（如散文和诗歌中的语言）至关重要。

The opposite of iconicity is arbitrariness; in an arbitrary sign, there is nothing in the form of the sign that resembles aspects of its meaning. 象似性的反面是任意性;在任意性符号中，符号的形式与其意义没有任何相似之处。
