The Judgment (Tuanzhuan) states that Gua signifies decision, specifically the strong deciding over the weak. Also, according to Jiyun (Collected Rhymes), it is pronounced jué. It refers to the object used to release a bowstring. It is interchangeably written as guài. According to the Zhengzitong (Correction of Character Meaning), in the Zihui (Collection of Characters), the character guài appears in the Zi Collection under the Again (yòu) radical; this is a duplication and should be deleted. Note: In the Shuowen Jiezi (Explanation of Graphs and Analysis of Characters), the character guài is categorized under the Again (yòu) radical. However, in modern canonical texts, the character guài is formed with the Big (dà) radical and should be categorized under the Big (dà) radical; one should only delete the gloss for the character guài under the Again (yòu) radical.
