feedback (English)

Where does "feedback" come from?

The word 'feedback' is a straightforward compound of the English 'feed' and 'back.' While 'feed' traces back to Proto-Indo-European roots involving protection and grazing, 'back' finds its origins in Germanic terms for the rear of the body. Combined, they evolved from describing simple nourishment to representing a system where information or energy is looped to the start to control results.
