About
The character 筌, constructed from the bamboo radical 竹 positioned above the phonetic component 全, originally designated a specific type of bamboo fish trap used in historical fishing practices. Its structural composition directly reflects this function, with the radical denoting the material and the phonetic component suggesting its pronunciation. Over time, while the primary literal meaning of the physical trap persisted, the character gained a metaphorical dimension in classical literature, notably within the idiom 得鱼忘筌, where it represents a means or method that becomes overlooked once an end is achieved. The form of the character has remained stable, with its traditional writing identical to its contemporary representation, maintaining the semantic and phonetic relationship inherent in its components.
