The word 'feedback' refers to information or reactions provided about a person's performance or a completed task, which can be used to improve or enhance future outcomes. It serves as a critical component in communication, allowing for adjustments based on responses from others. Feedback can be positive, highlighting strengths and successes, or constructive, pointing out areas that need improvement.
The term 'feedback' is derived from the combination of 'feed', meaning to supply or provide, and 'back', indicating a return to the source. It originated in the early 20th century and became more widely used in the realms of electronics and psychology before entering common usage in various fields.
