The Chinese word 反馈 (fǎnkuì), meaning "feedback", is a compound formed by combining two meaningful characters: 反 (fǎn), which carries the core idea of "to return", "to reverse", or "back", and 馈 (kuì), which means "to give" or "to offer". When combined, they create the literal concept of "returning a giving" or "giving back", which perfectly encapsulates the process of providing a responsive return of information, results, or a signal to its origin, hence the modern translation as "feedback". This formation is typical of modern Chinese terminology, where existing characters are logically paired to describe new or technical concepts.
