🎁 回馈 = 回 return + 馈 give a gift = giving back: a reward or feedback
回 means to return or send back; 馈 means to present a gift or provide. Together they mean giving something back in return, whether a reward or feedback. The 馈 element carries a food radical 饣, tying it to the old sense of offering a meal.
回 — enclosure 囗 + smaller 囗 inside
回 is a pictograph of a swirling whirlpool or coiled spiral, shown as nested squares in modern form. The original meaning was 'to revolve' or 'turn around,' which extended to 'return' and 'a time/occurrence.' It also appears as a phonetic in characters like 茴 and 廻.
