🌱She tells herself that the money she spends on luxuries eventually percolates down to the needy. 🌳Percolate comes from a Latin verb meaning "to put through a sieve." Something that percolates filters through something else, just as small particles pass through a sieve. Water is drawn downward through the soil, and this percolation usually cleans the water. A slow rain is ideal for percolating into the soil, since in a violent rainstorm most of it quickly runs off. For this reason, drip irrigation is the most effective and water-conserving form of irrigation. Percolation isn't always a physical process; awareness of an issue may percolate slowly into the minds of the public, just as Spanish words may gradually percolate into English, often starting in the Southwest. pervade To spread through all parts of something.
🌱We all knew that more job cuts were coming, and the entire office was pervaded with anxiety. 🌳Pervade can be used to describe something physical: a chemical odor may pervade a building, for example, and most scientists believe that outer space is pervaded by mysterious "dark matter." But the word usually doesn't refer to anything that could be detected by scientific instruments. Thus, humor may pervade a novel, gloom may pervade a gathering, and corruption may pervade a government. And something pervasive exists in every part of something: fatherlessness may be a pervasive problem in poor neighborhoods, for instance, and pervasive optimism sometimes causes the stock market to soar. permeate 1、 To spread throughout.
2、 To pass through the pores or small openings of.
🌱On Saturday mornings back in those days, the aroma of fresh pies and breads would permeate almost every house on the block. 🌳Permeate is often a synonym for pervade. We could say, for example, that at exam time the campus is either "permeated" or "pervaded" by a sense of dread. But the two words aren't identical. For one thing, permeate can mean simply "pass through," and is often used when talking about liquids; thus, a boot can be permeated by water, though certain oils make leather less permeable, and you might just want to buy boots made of impermeable material. And things may "pass through" in a nonphysical way as well; so you might say that anxiety about climate change has started to permeate into the public's consciousness—but once anxiety has become pervasive it's pretty much taken over. persevere To keep at something in spite of difficulties, opposition, or discouragement.
🌱For ten years she persevered in her effort to find out what the government knew about her husband's disappearance. 🌳The early settlers of the New World persevered in the face of constant hardship and danger. The Pilgrims of Plymouth Plantation lost half their number in the first winter to disease and hunger, but their perseverance paid off, and within five years their community was healthy and self-sufficient. Perhaps more remarkable are all the solitary inventors who have persevered in pursuing their visions for years, lacking any financial support and laughed at by the public.
