overflow, inundate, spill
溢 centers on liquid exceeding its bounds: overflowing, spilling over, or flooding an area. The idea extends naturally to being filled to the brim or inundated.
溢 combines 氵 (water) with 益, which likely contributes both sound and the idea of increase or fullness, together suggesting water rising and overflowing.
Water 氵 plus 益 (increase/benefit) creates a vivid image: water increasing until it spills over the edge of a container. 溢 is overflow.
For イツ, imagine water overflowing from a pot and someone shouting 'It's overflowing!' — the 'It's' sound cues イツ while the water spills everywhere.
