Etymology

The word "mutual" traces back to Latin mutuus, originally meaning "borrowed" or "reciprocal," reflecting the idea of exchange or shared action. Over time, it evolved in Middle French as mutuel before entering English in the 15th century, retaining its core sense of reciprocity. The morpheme mut captures the concept of change or exchange, while -ual turns it into an adjective describing a shared relationship.
