Literary notes about percolate (AI summary)
The word "percolate" is used in literature to evoke both a tangible process of liquid filtering through a medium and a more abstract, gradual diffusion of ideas or emotions. In its literal sense, it describes the slow passage of substances such as water, oil, or coffee through porous materials—for instance, oil seeping through cement [1] or water moving smoothly over stone [2, 3]. Metaphorically, it captures the subtle process by which thoughts, cultural practices, or secrets steadily seep into collective consciousness or individual minds, as when knowledge slowly penetrates the public mind [4] or transformative ideas permeate personal awareness [5]. This dual usage enriches literary narratives by drawing a parallel between physical filtration and the gradual unfolding of intellectual or emotional change.
