feeder

The term carries a strong sense of dependency and directional flow. It describes the point of origin in a supply chain, whether that chain is biological, mechanical, or hydrological. There is an inherent power dynamic implied, where the feeder controls the resource and the recipient relies upon it for sustenance or operation. In modern social contexts, the word can take on a darker or more specialized connotation when referring to people who encourage others to gain weight, shifting the meaning from a neutral act of providing nourishment to a specific behavioral pattern.
