The crossword solution for the term 'seeped (through)' is 'osmosed' (7 letters). Osmosis is a process in which molecules of a solvent, such as water, pass through a semipermeable membrane from a less concentrated solution into a more concentrated one. This process can be seen in nature when water passes through a plant's cell walls and into its cells. In this way, osmosis helps plants absorb nutrients and water from the soil.
