The word 频道 is formed by combining two meaningful characters: 频 (pín), which conveys the idea of "frequency" or "repetition", and 道 (dào), which means a "path", "way", or "channel". They are joined not by grammar but by semantic compounding, where the concept of a "frequency path" directly and logically creates the modern meaning for a transmission channel, such as a television or radio channel. It is a direct conceptual fusion where the first character specifies the type (frequency-based) and the second character specifies the category (a conduit or pathway).
