The word 角落 is formed through a vivid visual and spatial metaphor. The first character, 角, literally means "corner" or "angle", picturing the sharp meeting point of two lines or walls. It is combined with 落, which means "to fall" or "to settle". Together, they create the concept of a "corner" not just as a geometric intersection, but as a specific, often overlooked place where things naturally come to rest, accumulate, or are tucked away, the image is of a space where something has settled into the angle, forming a secluded nook.
