percolate

To percolate means to filter through something or to spread gradually, like liquid slowly passing through coffee grounds. The word first referred to the movement of liquid in coffee making, and from there it came to describe how ideas, news, feelings, or changes move and develop over time. For example: "Rumors began to percolate among the employees after the meeting," meaning the rumors started spreading slowly from person to person.

Percolate is not about a quick or forceful spread; it is about something moving in slowly, often in a quiet way. It often suggests that something is passing through layers, groups, or stages before it is fully understood or completed. A new policy might percolate through an organization before being fully implemented, with people hearing about it bit by bit.

You can also use percolate to describe how thoughts or feelings develop within a person. "The idea began to percolate in her mind" means she started thinking about it more deeply, letting it sit until a clearer understanding emerged. It can suggest that an idea needs time before it becomes clear or fully formed.

So whether you are describing the spread of information, the growth of an idea, or the movement of liquid through coffee grounds, percolate suggests a slow, gradual process of filtering, spreading, or taking shape over time.
