The word 途径 is formed by combining two characters, 途 (tú) and 径 (jìng), which both individually mean a "path" or "way". It is a classical example of a coordinated compound, where two synonymous elements are joined to create a single, more abstract and comprehensive concept. The fusion metaphorically broadens the idea from a simple physical road to encompass the notion of a "method", "channel", or "approach", effectively picturing multiple possible paths leading to a destination or goal.
