The word "放手" is formed through a direct and vivid conceptual combination. It merges the character for "to release" or "to let go" (放) with the character for "hand" (手), creating a concrete mental image of opening one's grasp and physically releasing something from the hand. This literal action is then extended metaphorically to encompass the broader, abstract idea of relinquishing control, ceasing an endeavor, or giving up a preoccupation, allowing the physical act to perfectly symbolize the intangible mental or emotional release.
