dissipate vs scatter
Dissipate and scatter both spread things apart, with a difference in what is left. Dissipate is to scatter and gradually fade until nothing remains. Scatter is to throw or send things in different directions so they spread out irregularly, but the things themselves remain. Dissipate fades to nothing; scatter flings apart but the things stay.
Quick rule: spread out and fade until nothing is left → dissipate; throw things apart at random, the things remaining → scatter.
A low white fog lies thick over the hills, snagged and going nowhere; then the light leans in and it begins to thin and lift, tearing into pale patches that drift and stretch until there is simply nothing of it left, and the bare hills stand in clean air.
/ˈdɪsɪpeɪt//ˈdɪsɪpeɪt/·verbA tight triangle of balls sits racked in perfect order; then the cue ball cracks into the apex and in one instant the order is gone — balls bolt off in every direction, cannoning off the rails, a couple flying clean off the table, no two taking the same trip.
/ˈskætər//ˈskætə/·verbBoth spread things out, but scatter leaves them and dissipate loses them. Dissipate, from dis- 'apart' and supare 'to throw', thins something out until it is gone — fog, heat, tension. Scatter, close to 'shatter', throws things out in every direction so they land with no pattern, but each thing survives. Fog dissipates off the hills until nothing is left; a break shot scatters the balls, which all still lie on the table. One vanishes; the other merely spreads.
What each means
dissipate
To dissipate is to scatter and fade until nothing is left: fog dissipates as the sun climbs, tension dissipates after an argument, energy dissipates as heat. Unlike disperse, where a thing spreads out but still exists somewhere, what dissipates loses itself completely — it thins into the air and is gone. From the Latin dissipare, 'to scatter', it can also mean to squander: a fortune may dissipate as surely as mist. Either way, something concentrated ends as nothing.
scatter
To scatter is to send things flying apart so they land here and there with no order — a handful of gravel flung across a path, papers blown off a desk, a flock startled into the air. The word stresses suddenness and irregularity: what scatters is strewn unevenly and left wherever it falls, not neatly distributed. It works both ways, much like its cousin disperse — a crowd can scatter, or police can scatter it — but where disperse suggests an even thinning-away, scatter keeps that sense of a sudden, random fling.

How to remember the difference
Ask whether the things vanish or just spread. Dissipate thins a thing out until nothing remains — a fog lifting off the hills into clean air. Scatter flings things apart with no pattern, but they all still exist — balls flung across a table. If something spreads out and fades to nothing, that is dissipate; if things are thrown apart but remain, that is scatter.
Examples
dissipate
- The tension in the room dissipated once she laughed.
- By noon the fog had completely dissipated.
- His early energy slowly dissipated over the evening.
scatter
- A gust scattered the papers across the yard.
- The crowd scattered the moment the alarm sounded.
- She scattered the seeds by hand across the bed.
The tell is what is left: scatter spreads things out but they still exist somewhere, while what dissipates loses itself completely and is gone. Dissipate is gradual and usually of formless things (fog, heat, mood); scatter is sudden and usually of countable things (balls, seeds, people). One vanishes; the other survives, spread wide.
In TOEFL & IELTS
A close pair worth separating in exam writing. Scatter is for countable things flung apart but still there — 'scattered papers', 'scattered showers'. Dissipate is for something formless thinning to nothing — 'the heat dissipated', 'the crowd's anger dissipated'. Examiners reward the tell: scatter spreads things that remain, dissipate fades a thing to nothing. The nouns are dissipation and scattering.
FAQ
- What is the difference between dissipate and scatter?
- Dissipate is to scatter and gradually fade until nothing remains, while scatter is to throw or send things in different directions so they spread out irregularly, with the things themselves remaining. Dissipate fades to nothing; scatter flings apart but the things stay. In the scenes above, a bank of fog thins and lifts off the hills until the air is clear, whereas a racked triangle of balls bolts apart but all still lie on the table.
- Are dissipate and scatter the same?
- They overlap — both spread things out — but the ending differs. When something scatters, the things spread apart and still exist somewhere; when something dissipates, it thins out and is gone completely. You scatter seeds that then sprout; fog dissipates and leaves nothing. The tell is what is left: things remaining (scatter) versus nothing at all (dissipate).
- What does dissipate mean in physics?
- To spread energy out until it can no longer do useful work — friction dissipates a car's motion as heat, which thins into the surroundings and cannot be gathered back. Scatter is more about countable things flung apart; light can be scattered by particles yet still exist, whereas dissipated energy is degraded and gone. One spreads and survives, the other fades to nothing.
- Does scatter mean the things disappear?
- No — that is the key difference. When things scatter they spread apart but each survives, as the balls all still lie somewhere on the table in the scene above. Dissipate is the one that ends in nothing, like the fog burning off the hills. So scatter is a spreading of things that remain; dissipate a fading of something until it is gone.
- What are the noun forms of dissipate and scatter?
- Dissipation and scattering. 'Dissipation' names a fading-away, with a physics sense (energy dissipation) and a moral one (a life of dissipation); scattering names a flinging-apart, and 'a scatter' can name a loose, irregular spread. The nouns keep the tell: a vanishing versus a spread of things that remain.
- Which word fits fog clearing from hills?
- Dissipate. Fog dissipates when it thins and fades until nothing of it is left, as in the scene above. Scatter would mean the fog was flung apart but still there, which is not what happens. The tell is the ending: dissipate fades to nothing, scatter spreads things that remain.
- Which word fits papers blown across a yard?
- Scatter. Papers scatter when a gust flings them apart in every direction, but they all still lie on the ground, as the balls do in the scene above. Dissipate would mean they thinned away to nothing, which paper does not do. The tell is what is left: scatter spreads things that remain, dissipate fades a thing to nothing.
