dissipate vs intersect
Dissipate and intersect are opposites in direction and outcome. Dissipate is to scatter and gradually fade until nothing is left. Intersect is to cross at a point and continue, or to have a point in common. Dissipate thins a thing out to nothing; intersect brings two paths to a shared point.
Quick rule: scatter and fade until nothing is left → dissipate; two paths cross at a shared point and continue → intersect.
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 car comes along the flat road and another drops down the road that crosses it; for one instant they share the very same square of ground and the junction flares — then they are past it, each still on its first heading.
/ˌɪntərˈsekt//ˌɪntəˈsekt/·verbOne lets a thing fade to nothing; the other brings two paths to a shared point. Dissipate, from dis- 'apart' and supare 'to throw', thins something out until it is gone. Intersect, from inter- 'between' and secare 'to cut', means two things cross and share a point, then continue. A mist dissipates and is gone; two roads intersect at a junction. One fades away everywhere; the other meets at one point.
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.
intersect
To intersect is for two lines, roads, or paths to cross each other at a point and carry on past it — from the Latin inter- 'between' and secare 'to cut', literally to cut between. Where roads intersect there is a junction; where two sets intersect there are the members they share. The word runs figuratively too: two fields of study intersect where their concerns overlap. Unlike paths that meet and stop, intersecting lines cross and keep going, then diverge again beyond the point.

How to remember the difference
Ask whether a thing fades away or two paths meet. Dissipate thins a thing out until nothing remains — a fog lifting off the hills. Intersect brings two paths to one shared point, then each carries on — two roads at a junction. If a thing fades to nothing, that is dissipate; if two paths cross at a shared point, they intersect.
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.
intersect
- The two roads intersect at the edge of town.
- Their research interests intersect at climate policy.
- The line intersects the circle at two points.
Dissipate thins a thing out to nothing; intersect brings two paths to a single shared point. They oppose in direction and outcome — a fading-away versus a meeting at a point. Intersect leaves the two paths intact; dissipate leaves nothing.
FAQ
- What is the difference between dissipate and intersect?
- Dissipate is to scatter and gradually fade until nothing remains, while intersect is to cross at a point and continue past it, or to have a point in common. Dissipate thins a thing out to nothing; intersect brings two paths to a shared point. In the scenes above, a bank of fog thins away until nothing of it is left, whereas two roads cross at a single junction.
- Are dissipate and intersect opposites?
- In direction and outcome, yes: dissipate thins a thing out until it is gone, while intersect brings two paths to the very same point. One fades to nothing, the other meets at one spot. They are not an everyday pair, since intersect concerns two crossing paths and dissipate a thing fading, but the contrast is exact.
- What does it mean when two fields intersect?
- It means they share common ground — a point or area where they overlap — while staying separate fields, as with 'law and ethics intersect'. The image is the crossing roads in the scene above. Dissipate is the far opposite: a thing thinning away to nothing, with no shared point at all. So intersect finds a meeting point, dissipate fades a thing away.
- 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. Intersect has no such sense; it means two paths crossing at a point. So one fades energy to nothing, the other marks where two paths meet.
- What are the noun forms of dissipate and intersect?
- Dissipation and intersection. 'Dissipation' names a fading-away, with a physics sense and a moral one; 'an intersection' names a crossing point — a road intersection, or the elements two sets share. The nouns keep the contrast: a vanishing versus a shared point.
- Which word fits two roads crossing?
- Intersect. Two roads intersect where they cross and continue, sharing one point, as in the scene above. Dissipate would mean a thing fading to nothing. The tell is direction and outcome: intersect brings two paths to one point, dissipate thins a thing away.
- 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. Intersect would mean two paths meeting at a point. The tell is outcome: dissipate fades to nothing, intersect converges on a shared point.
