Origin

The character combines water (the three-stroke element on the left) with an element meaning "increase" or "layering" (on the right). Water that goes deep requires many layers of depth beneath the surface, so the combination came to represent the idea of something being deep or profound. The character captures how water extends downward into greater and greater depths, which then naturally extended to mean deepening in general—making something more intense or stronger.
